Resolved Issues
---------------
Drivers
~~~~~~~
+* **e1000/base: Synchronize PHY interface on non-ME systems.**
+
+ On power up, the MAC - PHY interface needs to be set to PCIe, even if
+ cable is disconnected. In ME systems, the ME handles this on exit from
+ Sx(Sticky mode) state. In non-ME, the driver handles it. Add a check
+ for non-ME system to the driver code that handles that.
+
+* **e1000/base: Increase timeout of reset check.**
+
+ Previously, in check_reset_block RSPCIPHY was polled for 100 ms before
+ determining that the ME veto is set. It's not enough. It need to be increased
+ to 300 ms.
+
+* **e1000/base: Disable IPv6 extension header parsing on 82575.**
+
+ Disable IPv6 options as per hardware limitation.
+
+* **e1000/base: Prevent ULP flow if cable connected.**
+
+ Enabling ulp on link down when cable is connect caused an infinite
+ loop of linkup/down indications in the NDIS driver.
+ After discussed, correct flow is to enable ULP only when cable is
+ disconnected.
+
+* **e1000/base: Support different EEARBC for i210.**
+
+ EEARBC has changed on i210. It means EEARBC has a different address on
+ i210 than on other NICs. So, add a new entity named EEARBC_I210 to the
+ register list and make sure the right one is being used on i210.
+
+* **e1000/base: Fix K1 configuration**
+
+ This patch is for the following updates to the K1 configurations:
+ Tx idle period for entering K1 should be 128 ns.
+ Minimum Tx idle period in K1 should be 256 ns.
+
+* **e1000/base: Fix link detect flow**
+
+ In case that auto-negotiate is not enabled, call
+ e1000_setup_copper_link_generic instead of e1000_phy_setup_autoneg.
+
+* **e1000/base: Fix link check for i354 M88E1112 PHY**
+
+ e1000_check_for_link_media_swap() is supposed to check PHY page 0 for
+ copper and PHY page 1 for "other" (fiber) link. We switched back from
+ page 1 to page 0 too soon, before e1000_check_for_link_82575() is
+ executed and we were never finding link on fiber (other).
+
+ If the link is copper, as the M88E1112 page address is set to 1, it should be
+ set back to 0 before checking this link.
+
+* **e1000/base: Fix beacon duration for i217**
+
+ Fix for I217 Packet Loss issue - The Management Engine sets the FEXTNVM4
+ Beacon Duration incorrectly. This fix ensures that the correct value will
+ always be set. Correct value for this field is 8 usec.
+
+* **e1000/base: Fix TIPG for non 10 half duplex mode**
+
+ TIPG value is increased when setting speed to 10 half to prevent
+ packet loss. However, it was never decreased again when speed
+ changes. This caused performance issues in the NDIS driver.
+ Fix this to restore TIPG to default value on non 10 half.
+
+* **e1000/base: Fix reset of DH89XXCC SGMII**
+
+ For DH89XXCC_SGMII, write flush leaves registers of this device trashed
+ (0xFFFFFFFF). Add check for this device.
+ Also, after both for Port SW Reset and Device Reset case, platform should
+ wait at least 3ms before reading any registers. Since waiting is
+ conditionally executed only for Device Reset - remove the condition.
+
+* **e1000/base: Fix redundant PHY power down for i210**
+
+ Bit 11 of PHYREG 0 is used to power down PHY. The use of PHYREG 16 is
+ unnecessary any more.
+
+* **e1000/base: fix jumbo frame CRC failures**
+
+ Change the value of register 776.20[11:2] for jumbo mode from 0x1A to 0x1F.
+ This is to enlarge the gap between read and write pointers in the TX Fifo.
+ And replace the magic number with a macro by the way.
+
+* **e1000/base: Fix link flap on 82579**
+
+ Several customers have reported a link flap issue on 82579. The symptoms
+ are random and intermittent link losses when 82579 is connected to specific
+ switches. Issue has been root caused as interoperability problem between
+ the NIC and at least some Broadcom PHYs in the Energy Efficient Ethernet
+ wake mechanism.
+ To fix the issue, we are disabling the Phase Locked Loop shutdown in 100M
+ Low Power Idle. This solution will cause an increase of power in 100M EEE
+ link. It may cost additional 28mW in this specific mode.
+
* **igb: Fixed IEEE1588 frame identification in I210.**
Fixed issue where the flag PKT_RX_IEEE1588_PTP was not being set
VF needs the PF interrupt support initialized even if not started.
+* **igb: Fixed VF MAC address when using with DPDK PF.**
+
+ Assign a random MAC address in VF when not assigned by PF.
+
* **ixgbe: Fixed issue with X550 DCB.**
Fixed a DCB issue with x550 where for 8 TCs (Traffic Classes), if a packet
Fixed the issue of not freeing memzone in the call to free the memory for
adminq DMA.
+* **mlx: Fixed driver loading.**
+
+ The mlx drivers were unable to load when built as a shared library,
+ due to a missing symbol in mempool library.
+
+* **mlx4: Performance improvements.**
+
+ Fixed bugs in TX and RX flows that improves mlx4 performance.
+
+* **mlx4: Fixed Tx loss after initialization.**
+
+* **mlx4: Fixed scattered Tx with too many segments.**
+
+* **mlx4: Fixed memory registration for indirect mbuf data.**
+
* **vhost: Fixed Qemu shutdown.**
Fixed issue with libvirt ``virsh destroy`` not killing the VM.
Examples
~~~~~~~~
+* **l3fwd: Fixed crash with IPv6.**
+
+* **vhost_xen: Fixed compile error.**
+
Other
~~~~~
+* This release drops compatibility with Linux kernel 2.6.33. The minimum
+ kernel requirement is now 2.6.34.
+
Known Issues
------------
+* Some drivers do not fill the packet type when receiving.
+ As the l3fwd example application requires this info, the i40e vector
+ driver must be disabled to benefit of the packet type with i40e.
+
+* **Mellanox PMDs (mlx4 & mlx5):**
+
+ * PMDs do not support DPDK integrated shared library.
+
+ * There is performance degradation for small packets when PMD
+ is compiled with SGE_WR_N = 4 compared to the performance when SGE_WR_N = 1.
+ If scattered packets are not used it is recomended
+ to compile PMD with SGE_WR_N = 1.
+
+ * When a Multicast or Broadcast packet is sent to the SR-IOV mlx4 VF,
+ it is returned back to the port.
+
API Changes
-----------
structures: rte_eth_dcb_rx_conf, rte_eth_dcb_tx_conf,
rte_eth_vmdq_dcb_conf, rte_eth_vmdq_dcb_tx_conf.
+* The rte_eth_rx_queue_count() function now returns "int" instead of "uint32_t"
+ to allow the use of negative values as error codes on return.
+
* The function rte_eal_pci_close_one() is removed.
It was replaced by rte_eal_pci_detach().
* The devargs union field virtual is renamed to virt for C++ compatibility.
-
ABI Changes
-----------
* The new fields rx_desc_lim and tx_desc_lim are added into rte_eth_dev_info
structure.
+* For debug builds, the functions rte_eth_rx_burst(), rte_eth_tx_burst()
+ rte_eth_rx_descriptor_done() and rte_eth_rx_queue_count() will
+ no longer be separate functions in the DPDK libraries. Instead, they will
+ only be present in the rte_ethdev.h header file.
+
* The maximum number of queues per port CONFIG_RTE_MAX_QUEUES_PER_PORT is
increased to 1024.
* librte_table LPM: A new parameter to hold the table name will be added to
the LPM table parameter structure.
+* librte_table hash: The key mask parameter is added to the hash table
+ parameter structure for 8-byte key and 16-byte key extendible bucket
+ and LRU tables.
+
* librte_port: Macros to access the packet meta-data stored within the packet
buffer has been adjusted to cover the packet mbuf structure.
* librte_cfgfile: Allow longer names and values by increasing the constants
CFG_NAME_LEN and CFG_VALUE_LEN to 64 and 256 respectively.
+* vhost: a new field enabled is added to the vhost_virtqueue structure.
+
+* vhost: a new field virt_qp_nb is added to virtio_net structure, and the
+ virtqueue field is moved to the end of virtio_net structure.
+
+* vhost: a new operation vring_state_changed is added to virtio_net_device_ops
+ structure.
+
+* vhost: a few spaces are reserved both at vhost_virtqueue and virtio_net
+ structure for future extension.
