14 Added functions to read, write and adjust system time in the NIC.

19 string name of each statistic, refer to the Extended Statistics section
20 of the programmers guide. Implemented the extended stats API for these
30 * **Added API in ethdev to retrieve RX/TX queue information.**
32 * Add the ability for the upper layer to query RX/TX queue information.

85 * **Added support for Mellanox ConnectX-4 adapters (mlx5).**
87 The mlx5 poll-mode driver implements support for Mellanox ConnectX-4 EN
88 and Mellanox ConnectX-4 Lx EN families of 10/25/40/50/100 Gb/s adapters.
90 Like mlx4, this PMD is only available for Linux and is disabled by default
91 due to external dependencies (libibverbs and libmlx5).
93 * **Enhanced support for virtio driver.**
95 * Virtio ring layout optimization (fixed avail ring)
99 * **Added vhost-user multiple queue support.**
101 * **Added port hotplug support to vmxnet3.**

112 * **eal/linux: Fixed epoll timeout.**
114 Fixed issue where the ``rte_epoll_wait()`` function didn't return when the
115 underlying call to ``epoll_wait()`` timed out.
121 * **igb: Fixed IEEE1588 frame identification in I210.**
123 Fixed issue where the flag PKT_RX_IEEE1588_PTP was not being set
124 in Intel I210 NIC, as EtherType in RX descriptor is in bits 8:10 of
125 Packet Type and not in the default bits 0:2.
127 * **igb: Fixed VF start with PF stopped.**
129 VF needs the PF interrupt support initialized even if not started.
131 * **ixgbe: Fixed issue with X550 DCB.**
133 Fixed a DCB issue with x550 where for 8 TCs (Traffic Classes), if a packet
134 with user priority 6 or 7 was injected to the NIC, then the NIC would only
135 put 3 packets into the queue. There was also a similar issue for 4 TCs.
137 * **ixgbe: Removed burst size restriction of vector RX.**
139 Fixed issue where a burst size less than 32 didn't receive anything.
141 * **ixgbe: Fixed VF start with PF stopped.**
143 VF needs the PF interrupt support initialized even if not started.
145 * **ixgbe: Fixed TX hang when RS distance exceeds HW limit.**
147 Fixed an issue when TX queue can hang when a lot of highly fragmented
148 packets have to be sent.
149 As part of that fix, tx_rs_thresh for ixgbe PMD is not allowed to be greater
150 then to 32 to comply with HW restrictions.
152 * **i40e: Fixed base driver allocation when not using first numa node.**
154 Fixed i40e issue that occurred when a DPDK application didn't initialize
155 ports if memory wasn't available on socket 0.
157 * **i40e: Fixed maximum of 64 queues per port.**
159 Fixed the issue in i40e of cannot supporting more than 64 queues per port,
160 though hardware actually supports that. The real number of queues may vary,
161 as long as the total number of queues used in PF, VFs, VMDq and FD does not
162 exceeds the hardware maximum.
164 * **i40e: Fixed statistics of packets.**
166 Added discarding packets on VSI to the stats and rectify the old statistics.
168 * **i40e: Fixed issue of not freeing memzone.**
170 Fixed the issue of not freeing memzone in the call to free the memory for
173 * **vhost: Fixed Qemu shutdown.**
175 Fixed issue with libvirt ``virsh destroy`` not killing the VM.
177 * **virtio: Fixed crash after changing link state.**
179 Fixed io permission in the interrupt handler.
181 * **virtio: Fixed crash when releasing queue.**
183 Fixed issue when releasing null control queue.
189 * **hash: Fixed memory allocation of Cuckoo Hash key table.**
191 Fixed issue where an incorrect Cuckoo Hash key table size could be
192 calculated limiting the size to 4GB.
194 * **hash: Fixed incorrect lookup if key is all zero.**
196 Fixed issue in hash library that occurred if an all zero
197 key was not added in the table and the key was looked up,
198 resulting in an incorrect hit.
200 * **hash: Fixed thread scaling by reducing contention.**
202 Fixed issue in hash library where, using multiple cores with
203 hardware transactional memory support, thread scaling did not work,
204 due to the global ring that is shared by all cores.
222 * The deprecated flow director API is removed.
223 It was replaced by rte_eth_dev_filter_ctrl().
225 * The dcb_queue is renamed to dcb_tc in following dcb configuration
226 structures: rte_eth_dcb_rx_conf, rte_eth_dcb_tx_conf,
227 rte_eth_vmdq_dcb_conf, rte_eth_vmdq_dcb_tx_conf.

253 It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
255 * The ethdev flow director structure rte_eth_fdir_flow_ext structure is changed.
256 New fields are added to support flow director filtering in VF.
258 * The size of the ethdev structure rte_eth_hash_filter_info is changed
259 by adding a new element rte_eth_input_set_conf in an union.
261 * The new fields rx_desc_lim and tx_desc_lim are added into rte_eth_dev_info
264 * The maximum number of queues per port CONFIG_RTE_MAX_QUEUES_PER_PORT is
267 * The mbuf structure was changed to support unified packet type.
268 It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
270 * The dummy malloc library is removed. The content was moved into EAL in 2.1.

275 the LPM table parameter structure.
277 * librte_port: Macros to access the packet meta-data stored within the packet
278 buffer has been adjusted to cover the packet mbuf structure.
280 * librte_cfgfile: Allow longer names and values by increasing the constants
281 CFG_NAME_LEN and CFG_VALUE_LEN to 64 and 256 respectively.
