7 * **Added e1000 Rx interrupt support.**
9 * **Added igb TSO support for both PF and VF.**
11 * **RSS enhancement on Intel x550 NIC**
13 * Support 512 entries RSS redirection table.
14 * Support per VF RSS redirection table.
16 * **Flow director enhancement on Intel x550 NIC**
18 * Add 2 new flow director modes on x550.
19 * One is MAC VLAN mode, the other is tunnel mode.
21 * **Added i40e vector RX/TX.**
23 * **Added i40e flow control support.**
25 * **Added fm10k TSO support for both PF and VF.**
27 * **New NIC Boulder Rapid support.**
29 Boulder Rapid is a new NIC of Intel's fm10k family.
31 * **Enhanced support for the Chelsio CXGBE driver.**
33 * Added support for Jumbo Frames.
34 * Optimize forwarding performance for Chelsio T5 40GbE cards.
36 * **Added support for Mellanox ConnectX-4 adapters (mlx5).**
38 The mlx5 poll-mode driver implements support for Mellanox ConnectX-4 EN
39 and Mellanox ConnectX-4 Lx EN families of 10/25/40/50/100 Gb/s adapters.
41 Like mlx4, this PMD is only available for Linux and is disabled by default
42 due to external dependencies (libibverbs and libmlx5).
44 * **Added vhost-user multiple queue support.**
46 * **Added port hotplug support to xenvirt.**
55 * **eal/linux: Fixed epoll timeout.**
57 Fixed issue where the ``rte_epoll_wait()`` function didn't return when the
58 underlying call to ``epoll_wait()`` timed out.
64 * **igb: Fixed IEEE1588 frame identification in I210.**
66 Fixed issue where the flag PKT_RX_IEEE1588_PTP was not being set
67 in Intel I210 NIC, as EtherType in RX descriptor is in bits 8:10 of
68 Packet Type and not in the default bits 0:2.
70 * **ixgbe: Fixed issue with X550 DCB.**
72 Fixed a DCB issue with x550 where for 8 TCs (Traffic Classes), if a packet
73 with user priority 6 or 7 was injected to the NIC, then the NIC would only
74 put 3 packets into the queue. There was also a similar issue for 4 TCs.
76 * **ixgbe: Removed burst size restriction of vector RX.**
78 Fixed issue where a burst size less than 32 didn't receive anything.
80 * **i40e: Fixed base driver allocation when not using first numa node.**
82 Fixed i40e issue that occurred when a DPDK application didn't initialize
83 ports if memory wasn't available on socket 0.
85 * **vhost: Fixed Qemu shutdown.**
87 Fixed issue with libvirt ``virsh destroy`` not killing the VM.
89 * **virtio: Fixed crash after changing link state.**
91 Fixed io permission in the interrupt handler.
93 * **virtio: Fixed crash when releasing queue.**
95 Fixed issue when releasing null control queue.
101 * **hash: Fixed memory allocation of Cuckoo Hash key table.**
103 Fixed issue where an incorrect Cuckoo Hash key table size could be
104 calculated limiting the size to 4GB.
122 * The deprecated flow director API is removed.
123 It was replaced by rte_eth_dev_filter_ctrl().
125 * The dcb_queue is renamed to dcb_tc in following dcb configuration
126 structures: rte_eth_dcb_rx_conf, rte_eth_dcb_tx_conf,
127 rte_eth_vmdq_dcb_conf, rte_eth_vmdq_dcb_tx_conf.
129 * The function rte_eal_pci_close_one() is removed.
130 It was replaced by rte_eal_pci_detach().
132 * The deprecated ACL API ipv4vlan is removed.
134 * The deprecated hash function rte_jhash2() is removed.
135 It was replaced by rte_jhash_32b().
137 * The deprecated KNI functions are removed:
138 rte_kni_create(), rte_kni_get_port_id() and rte_kni_info_get().
140 * The deprecated ring PMD functions are removed:
141 rte_eth_ring_pair_create() and rte_eth_ring_pair_attach().
143 * The devargs union field virtual is renamed to virt for C++ compatibility.
149 * The EAL and ethdev structures rte_intr_handle and rte_eth_conf were changed
150 to support Rx interrupt. It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
152 * The ethdev flow director entries for SCTP were changed.
153 It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
155 * The mbuf structure was changed to support unified packet type.
156 It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
158 * The dummy malloc library is removed. The content was moved into EAL in 2.1.
160 * The LPM structure is changed. The deprecated field mem_location is removed.
162 * librte_table LPM: A new parameter to hold the table name will be added to
163 the LPM table parameter structure.
165 * librte_port: Macros to access the packet meta-data stored within the packet
166 buffer has been adjusted to cover the packet mbuf structure.
168 * librte_cfgfile: Allow longer names and values by increasing the constants
169 CFG_NAME_LEN and CFG_VALUE_LEN to 64 and 256 respectively.
