7 * **Enhanced support for the Chelsio CXGBE driver.**
9 * Added support for Jumbo Frames.
10 * Optimize forwarding performance for Chelsio T5 40GbE cards.
12 * **Added vhost-user multiple queue support.**
21 * **eal/linux: Fixed epoll timeout.**
23 Fixed issue where the ``rte_epoll_wait()`` function didn't return when the
24 underlying call to ``epoll_wait()`` timed out.
30 * **ixgbe: Fixed issue with X550 DCB.**
32 Fixed a DCB issue with x550 where for 8 TCs (Traffic Classes), if a packet
33 with user priority 6 or 7 was injected to the NIC, then the NIC would only
34 put 3 packets into the queue. There was also a similar issue for 4 TCs.
36 * **ixgbe: Removed burst size restriction of vector RX.**
38 Fixed issue where a burst size less than 32 didn't receive anything.
40 * **i40e: Fixed base driver allocation when not using first numa node.**
42 Fixed i40e issue that occurred when a DPDK application didn't initialize
43 ports if memory wasn't available on socket 0.
45 * **vhost: Fixed Qemu shutdown.**
47 Fixed issue with libvirt ``virsh destroy`` not killing the VM.
49 * **virtio: Fixed crash after changing link state.**
51 Fixed io permission in the interrupt handler.
53 * **virtio: Fixed crash when releasing queue.**
55 Fixed issue when releasing null control queue.
61 * **hash: Fixed memory allocation of Cuckoo Hash key table.**
63 Fixed issue where an incorrect Cuckoo Hash key table size could be
64 calculated limiting the size to 4GB.
82 * The deprecated flow director API is removed.
83 It was replaced by rte_eth_dev_filter_ctrl().
85 * The function rte_eal_pci_close_one() is removed.
86 It was replaced by rte_eal_pci_detach().
88 * The deprecated ACL API ipv4vlan is removed.
90 * The deprecated hash function rte_jhash2() is removed.
91 It was replaced by rte_jhash_32b().
93 * The deprecated KNI functions are removed:
94 rte_kni_create(), rte_kni_get_port_id() and rte_kni_info_get().
96 * The deprecated ring PMD functions are removed:
97 rte_eth_ring_pair_create() and rte_eth_ring_pair_attach().
99 * The devargs union field virtual is renamed to virt for C++ compatibility.
105 * The EAL and ethdev structures rte_intr_handle and rte_eth_conf were changed
106 to support Rx interrupt. It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
108 * The ethdev flow director entries for SCTP were changed.
109 It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
111 * The mbuf structure was changed to support unified packet type.
112 It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
114 * The dummy malloc library is removed. The content was moved into EAL in 2.1.
116 * The LPM structure is changed. The deprecated field mem_location is removed.
118 * librte_table LPM: A new parameter to hold the table name will be added to
119 the LPM table parameter structure.
121 * librte_port: Macros to access the packet meta-data stored within the packet
122 buffer has been adjusted to cover the packet mbuf structure.
124 * librte_cfgfile: Allow longer names and values by increasing the constants
125 CFG_NAME_LEN and CFG_VALUE_LEN to 64 and 256 respectively.
