7 * **Added igb TSO support for both PF and VF.**
9 * **RSS enhancement on Intel x550 NIC**
11 * Support 512 entries RSS redirection table.
12 * Support per VF RSS redirection table.
14 * **Flow director enhancement on Intel x550 NIC**
16 * Add 2 new flow director modes on x550.
17 * One is MAC VLAN mode, the other is tunnel mode.
19 * **Enhanced support for the Chelsio CXGBE driver.**
21 * Added support for Jumbo Frames.
22 * Optimize forwarding performance for Chelsio T5 40GbE cards.
24 * **Added vhost-user multiple queue support.**
33 * **eal/linux: Fixed epoll timeout.**
35 Fixed issue where the ``rte_epoll_wait()`` function didn't return when the
36 underlying call to ``epoll_wait()`` timed out.
42 * **igb: Fixed IEEE1588 frame identification in I210.**
44 Fixed issue where the flag PKT_RX_IEEE1588_PTP was not being set
45 in Intel I210 NIC, as EtherType in RX descriptor is in bits 8:10 of
46 Packet Type and not in the default bits 0:2.
48 * **ixgbe: Fixed issue with X550 DCB.**
50 Fixed a DCB issue with x550 where for 8 TCs (Traffic Classes), if a packet
51 with user priority 6 or 7 was injected to the NIC, then the NIC would only
52 put 3 packets into the queue. There was also a similar issue for 4 TCs.
54 * **ixgbe: Removed burst size restriction of vector RX.**
56 Fixed issue where a burst size less than 32 didn't receive anything.
58 * **i40e: Fixed base driver allocation when not using first numa node.**
60 Fixed i40e issue that occurred when a DPDK application didn't initialize
61 ports if memory wasn't available on socket 0.
63 * **vhost: Fixed Qemu shutdown.**
65 Fixed issue with libvirt ``virsh destroy`` not killing the VM.
67 * **virtio: Fixed crash after changing link state.**
69 Fixed io permission in the interrupt handler.
71 * **virtio: Fixed crash when releasing queue.**
73 Fixed issue when releasing null control queue.
79 * **hash: Fixed memory allocation of Cuckoo Hash key table.**
81 Fixed issue where an incorrect Cuckoo Hash key table size could be
82 calculated limiting the size to 4GB.
100 * The deprecated flow director API is removed.
101 It was replaced by rte_eth_dev_filter_ctrl().
103 * The function rte_eal_pci_close_one() is removed.
104 It was replaced by rte_eal_pci_detach().
106 * The deprecated ACL API ipv4vlan is removed.
108 * The deprecated hash function rte_jhash2() is removed.
109 It was replaced by rte_jhash_32b().
111 * The deprecated KNI functions are removed:
112 rte_kni_create(), rte_kni_get_port_id() and rte_kni_info_get().
114 * The deprecated ring PMD functions are removed:
115 rte_eth_ring_pair_create() and rte_eth_ring_pair_attach().
117 * The devargs union field virtual is renamed to virt for C++ compatibility.
123 * The EAL and ethdev structures rte_intr_handle and rte_eth_conf were changed
124 to support Rx interrupt. It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
126 * The ethdev flow director entries for SCTP were changed.
127 It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
129 * The mbuf structure was changed to support unified packet type.
130 It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
132 * The dummy malloc library is removed. The content was moved into EAL in 2.1.
134 * The LPM structure is changed. The deprecated field mem_location is removed.
136 * librte_table LPM: A new parameter to hold the table name will be added to
137 the LPM table parameter structure.
139 * librte_port: Macros to access the packet meta-data stored within the packet
140 buffer has been adjusted to cover the packet mbuf structure.
142 * librte_cfgfile: Allow longer names and values by increasing the constants
143 CFG_NAME_LEN and CFG_VALUE_LEN to 64 and 256 respectively.
