11 RX/TX descriptors min/max/align numbers per queue for the device.
13 * **Added RSS dynamic configuration to bonding.**
15 * **Added e1000 Rx interrupt support.**
17 * **Added igb TSO support for both PF and VF.**
19 * **RSS enhancement on Intel x550 NIC**
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.**
31 * **Added i40e flow control support.**
33 * **Added DCB support to i40e PF driver.**
35 * **Added fm10k TSO support for both PF and VF.**
37 * **Added fm10k VMDQ support.**
39 * **New NIC Boulder Rapid support.**
41 Boulder Rapid is a new NIC of Intel's fm10k family.
43 * **Enhanced support for the Chelsio CXGBE driver.**
45 * Added support for Jumbo Frames.
46 * Optimize forwarding performance for Chelsio T5 40GbE cards.
48 * **Added support for Mellanox ConnectX-4 adapters (mlx5).**
50 The mlx5 poll-mode driver implements support for Mellanox ConnectX-4 EN
51 and Mellanox ConnectX-4 Lx EN families of 10/25/40/50/100 Gb/s adapters.
53 Like mlx4, this PMD is only available for Linux and is disabled by default
54 due to external dependencies (libibverbs and libmlx5).
56 * **Added vhost-user multiple queue support.**
58 * **Added port hotplug support to xenvirt.**
67 * **eal/linux: Fixed epoll timeout.**
69 Fixed issue where the ``rte_epoll_wait()`` function didn't return when the
70 underlying call to ``epoll_wait()`` timed out.
76 * **igb: Fixed IEEE1588 frame identification in I210.**
78 Fixed issue where the flag PKT_RX_IEEE1588_PTP was not being set
79 in Intel I210 NIC, as EtherType in RX descriptor is in bits 8:10 of
80 Packet Type and not in the default bits 0:2.
82 * **ixgbe: Fixed issue with X550 DCB.**
84 Fixed a DCB issue with x550 where for 8 TCs (Traffic Classes), if a packet
85 with user priority 6 or 7 was injected to the NIC, then the NIC would only
86 put 3 packets into the queue. There was also a similar issue for 4 TCs.
88 * **ixgbe: Removed burst size restriction of vector RX.**
90 Fixed issue where a burst size less than 32 didn't receive anything.
92 * **i40e: Fixed base driver allocation when not using first numa node.**
94 Fixed i40e issue that occurred when a DPDK application didn't initialize
95 ports if memory wasn't available on socket 0.
97 * **vhost: Fixed Qemu shutdown.**
99 Fixed issue with libvirt ``virsh destroy`` not killing the VM.
101 * **virtio: Fixed crash after changing link state.**
103 Fixed io permission in the interrupt handler.
105 * **virtio: Fixed crash when releasing queue.**
107 Fixed issue when releasing null control queue.
113 * **hash: Fixed memory allocation of Cuckoo Hash key table.**
115 Fixed issue where an incorrect Cuckoo Hash key table size could be
116 calculated limiting the size to 4GB.
134 * The deprecated flow director API is removed.
135 It was replaced by rte_eth_dev_filter_ctrl().
137 * The dcb_queue is renamed to dcb_tc in following dcb configuration
138 structures: rte_eth_dcb_rx_conf, rte_eth_dcb_tx_conf,
139 rte_eth_vmdq_dcb_conf, rte_eth_vmdq_dcb_tx_conf.
141 * The function rte_eal_pci_close_one() is removed.
142 It was replaced by rte_eal_pci_detach().
144 * The deprecated ACL API ipv4vlan is removed.
146 * The deprecated hash function rte_jhash2() is removed.
147 It was replaced by rte_jhash_32b().
149 * The deprecated KNI functions are removed:
150 rte_kni_create(), rte_kni_get_port_id() and rte_kni_info_get().
152 * The deprecated ring PMD functions are removed:
153 rte_eth_ring_pair_create() and rte_eth_ring_pair_attach().
155 * The devargs union field virtual is renamed to virt for C++ compatibility.
161 * The EAL and ethdev structures rte_intr_handle and rte_eth_conf were changed
162 to support Rx interrupt. It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
164 * The ethdev flow director entries for SCTP were changed.
165 It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
167 * The new fields rx_desc_lim and tx_desc_lim are added into rte_eth_dev_info
170 * The mbuf structure was changed to support unified packet type.
171 It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
173 * The dummy malloc library is removed. The content was moved into EAL in 2.1.
175 * The LPM structure is changed. The deprecated field mem_location is removed.
177 * librte_table LPM: A new parameter to hold the table name will be added to
178 the LPM table parameter structure.
180 * librte_port: Macros to access the packet meta-data stored within the packet
181 buffer has been adjusted to cover the packet mbuf structure.
183 * librte_cfgfile: Allow longer names and values by increasing the constants
184 CFG_NAME_LEN and CFG_VALUE_LEN to 64 and 256 respectively.
