21 * Support 512 entries RSS redirection table.
22 * Support per VF RSS redirection table.
24 * **Flow director enhancement on Intel x550 NIC**
26 * Add 2 new flow director modes on x550.
27 * One is MAC VLAN mode, the other is tunnel mode.
29 * **Added i40e vector RX/TX.**

47 * Added support for Jumbo Frames.
48 * Optimize forwarding performance for Chelsio T5 40GbE cards.
50 * **Added support for Mellanox ConnectX-4 adapters (mlx5).**
52 The mlx5 poll-mode driver implements support for Mellanox ConnectX-4 EN
53 and Mellanox ConnectX-4 Lx EN families of 10/25/40/50/100 Gb/s adapters.
55 Like mlx4, this PMD is only available for Linux and is disabled by default
56 due to external dependencies (libibverbs and libmlx5).
58 * **Enhanced support for virtio driver.**
60 * Virtio ring layout optimization (fixed avail ring)
62 * **Added vhost-user multiple queue support.**
64 * **Added port hotplug support to xenvirt.**
73 * **eal/linux: Fixed epoll timeout.**
75 Fixed issue where the ``rte_epoll_wait()`` function didn't return when the
76 underlying call to ``epoll_wait()`` timed out.
82 * **igb: Fixed IEEE1588 frame identification in I210.**
84 Fixed issue where the flag PKT_RX_IEEE1588_PTP was not being set
85 in Intel I210 NIC, as EtherType in RX descriptor is in bits 8:10 of
86 Packet Type and not in the default bits 0:2.
88 * **ixgbe: Fixed issue with X550 DCB.**
90 Fixed a DCB issue with x550 where for 8 TCs (Traffic Classes), if a packet
91 with user priority 6 or 7 was injected to the NIC, then the NIC would only
92 put 3 packets into the queue. There was also a similar issue for 4 TCs.
94 * **ixgbe: Removed burst size restriction of vector RX.**
96 Fixed issue where a burst size less than 32 didn't receive anything.
98 * **i40e: Fixed base driver allocation when not using first numa node.**
100 Fixed i40e issue that occurred when a DPDK application didn't initialize
101 ports if memory wasn't available on socket 0.
103 * **vhost: Fixed Qemu shutdown.**
105 Fixed issue with libvirt ``virsh destroy`` not killing the VM.
107 * **virtio: Fixed crash after changing link state.**
109 Fixed io permission in the interrupt handler.
111 * **virtio: Fixed crash when releasing queue.**
113 Fixed issue when releasing null control queue.
119 * **hash: Fixed memory allocation of Cuckoo Hash key table.**
121 Fixed issue where an incorrect Cuckoo Hash key table size could be
122 calculated limiting the size to 4GB.
140 * The deprecated flow director API is removed.
141 It was replaced by rte_eth_dev_filter_ctrl().
143 * The dcb_queue is renamed to dcb_tc in following dcb configuration
144 structures: rte_eth_dcb_rx_conf, rte_eth_dcb_tx_conf,
145 rte_eth_vmdq_dcb_conf, rte_eth_vmdq_dcb_tx_conf.
147 * The function rte_eal_pci_close_one() is removed.
148 It was replaced by rte_eal_pci_detach().
150 * The deprecated ACL API ipv4vlan is removed.
152 * The deprecated hash function rte_jhash2() is removed.
153 It was replaced by rte_jhash_32b().
155 * The deprecated KNI functions are removed:
156 rte_kni_create(), rte_kni_get_port_id() and rte_kni_info_get().
158 * The deprecated ring PMD functions are removed:
159 rte_eth_ring_pair_create() and rte_eth_ring_pair_attach().
161 * The devargs union field virtual is renamed to virt for C++ compatibility.
167 * The EAL and ethdev structures rte_intr_handle and rte_eth_conf were changed
168 to support Rx interrupt. It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
170 * The ethdev flow director entries for SCTP were changed.
171 It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
173 * The new fields rx_desc_lim and tx_desc_lim are added into rte_eth_dev_info
176 * The mbuf structure was changed to support unified packet type.
177 It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
179 * The dummy malloc library is removed. The content was moved into EAL in 2.1.
181 * The LPM structure is changed. The deprecated field mem_location is removed.
183 * librte_table LPM: A new parameter to hold the table name will be added to
184 the LPM table parameter structure.
186 * librte_port: Macros to access the packet meta-data stored within the packet
187 buffer has been adjusted to cover the packet mbuf structure.
189 * librte_cfgfile: Allow longer names and values by increasing the constants
190 CFG_NAME_LEN and CFG_VALUE_LEN to 64 and 256 respectively.
