114 * Optimize forwarding performance for Chelsio T5 40GbE cards.
116 * **Improved enic Tx packet rate.**
118 Reduced frequency of Tx tail pointer updates to the NIC.
120 * **Added support for Mellanox ConnectX-4 adapters (mlx5).**
122 The mlx5 poll-mode driver implements support for Mellanox ConnectX-4 EN
123 and Mellanox ConnectX-4 Lx EN families of 10/25/40/50/100 Gb/s adapters.
125 Like mlx4, this PMD is only available for Linux and is disabled by default
126 due to external dependencies (libibverbs and libmlx5).

155 a simple cooperative scheduler.
157 Due to its experimental state this application may change without notice.
158 The application is supported only for Linux x86_64.
167 * **eal/linux: Fixed epoll timeout.**
169 Fixed issue where the ``rte_epoll_wait()`` function didn't return when the
170 underlying call to ``epoll_wait()`` timed out.
176 * **e1000/base: Synchronize PHY interface on non-ME systems.**
178 On power up, the MAC - PHY interface needs to be set to PCIe, even if
179 cable is disconnected. In ME systems, the ME handles this on exit from
180 Sx(Sticky mode) state. In non-ME, the driver handles it. Add a check
181 for non-ME system to the driver code that handles that.
183 * **e1000/base: Increase timeout of reset check.**
185 Previously, in check_reset_block RSPCIPHY was polled for 100 ms before
186 determining that the ME veto is set. It's not enough. It need to be increased
189 * **e1000/base: Disable IPv6 extension header parsing on 82575.**
191 Disable IPv6 options as per hardware limitation.
193 * **e1000/base: Prevent ULP flow if cable connected.**
195 Enabling ulp on link down when cable is connect caused an infinite
196 loop of linkup/down indications in the NDIS driver.
197 After discussed, correct flow is to enable ULP only when cable is
200 * **e1000/base: Support different EEARBC for i210.**
202 EEARBC has changed on i210. It means EEARBC has a different address on
203 i210 than on other NICs. So, add a new entity named EEARBC_I210 to the
204 register list and make sure the right one is being used on i210.
206 * **e1000/base: Fix K1 configuration**
208 This patch is for the following updates to the K1 configurations:
209 Tx idle period for entering K1 should be 128 ns.
210 Minimum Tx idle period in K1 should be 256 ns.
212 * **e1000/base: Fix link detect flow**
214 In case that auto-negotiate is not enabled, call
215 e1000_setup_copper_link_generic instead of e1000_phy_setup_autoneg.
217 * **e1000/base: Fix link check for i354 M88E1112 PHY**
219 e1000_check_for_link_media_swap() is supposed to check PHY page 0 for
220 copper and PHY page 1 for "other" (fiber) link. We switched back from
221 page 1 to page 0 too soon, before e1000_check_for_link_82575() is
222 executed and we were never finding link on fiber (other).
224 If the link is copper, as the M88E1112 page address is set to 1, it should be
225 set back to 0 before checking this link.
227 * **e1000/base: Fix beacon duration for i217**
229 Fix for I217 Packet Loss issue - The Management Engine sets the FEXTNVM4
230 Beacon Duration incorrectly. This fix ensures that the correct value will
231 always be set. Correct value for this field is 8 usec.
233 * **e1000/base: Fix TIPG for non 10 half duplex mode**
235 TIPG value is increased when setting speed to 10 half to prevent
236 packet loss. However, it was never decreased again when speed
237 changes. This caused performance issues in the NDIS driver.
238 Fix this to restore TIPG to default value on non 10 half.
240 * **e1000/base: Fix reset of DH89XXCC SGMII**
242 For DH89XXCC_SGMII, write flush leaves registers of this device trashed
243 (0xFFFFFFFF). Add check for this device.
244 Also, after both for Port SW Reset and Device Reset case, platform should
245 wait at least 3ms before reading any registers. Since waiting is
246 conditionally executed only for Device Reset - remove the condition.
248 * **e1000/base: Fix redundant PHY power down for i210**
250 Bit 11 of PHYREG 0 is used to power down PHY. The use of PHYREG 16 is
251 unnecessary any more.
253 * **e1000/base: fix jumbo frame CRC failures**
255 Change the value of register 776.20[11:2] for jumbo mode from 0x1A to 0x1F.
256 This is to enlarge the gap between read and write pointers in the TX Fifo.
257 And replace the magic number with a macro by the way.
259 * **e1000/base: Fix link flap on 82579**
261 Several customers have reported a link flap issue on 82579. The symptoms
262 are random and intermittent link losses when 82579 is connected to specific
263 switches. Issue has been root caused as interoperability problem between
264 the NIC and at least some Broadcom PHYs in the Energy Efficient Ethernet
266 To fix the issue, we are disabling the Phase Locked Loop shutdown in 100M
267 Low Power Idle. This solution will cause an increase of power in 100M EEE
268 link. It may cost additional 28mW in this specific mode.
270 * **igb: Fixed IEEE1588 frame identification in I210.**
272 Fixed issue where the flag PKT_RX_IEEE1588_PTP was not being set
273 in Intel I210 NIC, as EtherType in RX descriptor is in bits 8:10 of
274 Packet Type and not in the default bits 0:2.
276 * **igb: Fixed VF start with PF stopped.**
278 VF needs the PF interrupt support initialized even if not started.
280 * **igb: Fixed VF MAC address when using with DPDK PF.**
282 Assign a random MAC address in VF when not assigned by PF.
284 * **ixgbe: Fixed issue with X550 DCB.**
286 Fixed a DCB issue with x550 where for 8 TCs (Traffic Classes), if a packet
287 with user priority 6 or 7 was injected to the NIC, then the NIC would only
288 put 3 packets into the queue. There was also a similar issue for 4 TCs.
290 * **ixgbe: Removed burst size restriction of vector RX.**
292 Fixed issue where a burst size less than 32 didn't receive anything.
294 * **ixgbe: Fixed VF start with PF stopped.**
296 VF needs the PF interrupt support initialized even if not started.
298 * **ixgbe: Fixed TX hang when RS distance exceeds HW limit.**
300 Fixed an issue when TX queue can hang when a lot of highly fragmented
301 packets have to be sent.
302 As part of that fix, tx_rs_thresh for ixgbe PMD is not allowed to be greater
303 then to 32 to comply with HW restrictions.
305 * **i40e: Fixed base driver allocation when not using first numa node.**
307 Fixed i40e issue that occurred when a DPDK application didn't initialize
308 ports if memory wasn't available on socket 0.
310 * **i40e: Fixed maximum of 64 queues per port.**
312 Fixed the issue in i40e of cannot supporting more than 64 queues per port,
313 though hardware actually supports that. The real number of queues may vary,
314 as long as the total number of queues used in PF, VFs, VMDq and FD does not
315 exceeds the hardware maximum.
317 * **i40e: Fixed statistics of packets.**
319 Added discarding packets on VSI to the stats and rectify the old statistics.
321 * **i40e: Fixed issue of not freeing memzone.**
323 Fixed the issue of not freeing memzone in the call to free the memory for
326 * **mlx: Fixed driver loading.**
328 The mlx drivers were unable to load when built as a shared library,
329 due to a missing symbol in mempool library.
331 * **vhost: Fixed Qemu shutdown.**
333 Fixed issue with libvirt ``virsh destroy`` not killing the VM.
335 * **virtio: Fixed crash after changing link state.**
337 Fixed io permission in the interrupt handler.
339 * **virtio: Fixed crash when releasing queue.**
341 Fixed issue when releasing null control queue.
347 * **hash: Fixed memory allocation of Cuckoo Hash key table.**
349 Fixed issue where an incorrect Cuckoo Hash key table size could be
350 calculated limiting the size to 4GB.
352 * **hash: Fixed incorrect lookup if key is all zero.**
354 Fixed issue in hash library that occurred if an all zero
355 key was not added in the table and the key was looked up,
356 resulting in an incorrect hit.
358 * **hash: Fixed thread scaling by reducing contention.**
360 Fixed issue in hash library where, using multiple cores with
361 hardware transactional memory support, thread scaling did not work,
362 due to the global ring that is shared by all cores.
368 * **l3fwd: Fixed crash with IPv6.**
370 * **vhost_xen: Fixed compile error.**
376 * This release drops compatibility with Linux kernel 2.6.33. The minimum
377 kernel requirement is now 2.6.34.
383 * Some drivers do not fill the packet type when receiving.
384 As the l3fwd example application requires this info, the i40e vector
385 driver must be disabled to benefit of the packet type with i40e.
391 * The deprecated flow director API is removed.
392 It was replaced by rte_eth_dev_filter_ctrl().
394 * The dcb_queue is renamed to dcb_tc in following dcb configuration
395 structures: rte_eth_dcb_rx_conf, rte_eth_dcb_tx_conf,
396 rte_eth_vmdq_dcb_conf, rte_eth_vmdq_dcb_tx_conf.
398 * The rte_eth_rx_queue_count() function now returns "int" instead of "uint32_t"
399 to allow the use of negative values as error codes on return.
401 * The function rte_eal_pci_close_one() is removed.
402 It was replaced by rte_eal_pci_detach().
404 * The deprecated ACL API ipv4vlan is removed.
406 * The deprecated hash function rte_jhash2() is removed.
407 It was replaced by rte_jhash_32b().
409 * The deprecated KNI functions are removed:
410 rte_kni_create(), rte_kni_get_port_id() and rte_kni_info_get().
412 * The deprecated ring PMD functions are removed:
413 rte_eth_ring_pair_create() and rte_eth_ring_pair_attach().
415 * The devargs union field virtual is renamed to virt for C++ compatibility.
420 * The EAL and ethdev structures rte_intr_handle and rte_eth_conf were changed
421 to support Rx interrupt. It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
423 * The ethdev flow director entries for SCTP were changed.
424 It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
426 * The ethdev flow director structure rte_eth_fdir_flow_ext structure is changed.
427 New fields are added to support flow director filtering in VF.
429 * The size of the ethdev structure rte_eth_hash_filter_info is changed
430 by adding a new element rte_eth_input_set_conf in an union.
432 * The new fields rx_desc_lim and tx_desc_lim are added into rte_eth_dev_info
435 * For debug builds, the functions rte_eth_rx_burst(), rte_eth_tx_burst()
436 rte_eth_rx_descriptor_done() and rte_eth_rx_queue_count() will
437 no longer be separate functions in the DPDK libraries. Instead, they will
438 only be present in the rte_ethdev.h header file.
440 * The maximum number of queues per port CONFIG_RTE_MAX_QUEUES_PER_PORT is
443 * The mbuf structure was changed to support unified packet type.
444 It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
446 * The dummy malloc library is removed. The content was moved into EAL in 2.1.
448 * The LPM structure is changed. The deprecated field mem_location is removed.
450 * librte_table LPM: A new parameter to hold the table name will be added to
451 the LPM table parameter structure.
453 * librte_table hash: The key mask parameter is added to the hash table
454 parameter structure for 8-byte key and 16-byte key extendible bucket
457 * librte_port: Macros to access the packet meta-data stored within the packet
458 buffer has been adjusted to cover the packet mbuf structure.
460 * librte_cfgfile: Allow longer names and values by increasing the constants
461 CFG_NAME_LEN and CFG_VALUE_LEN to 64 and 256 respectively.
