7 * **Enabled freeing of ring.**
9 New function rte_ring_free() allows the user to free a ring
10 if it was created with rte_ring_create().

14 Define extended statistics naming scheme to store metadata in the name
15 string name of each statistic, refer to the Extended Statistics section
16 of the programmers guide. Implemented the extended stats API for these

40 * Support 512 entries RSS redirection table.
41 * Support per VF RSS redirection table.
43 * **Flow director enhancement on Intel x550 NIC**
45 * Add 2 new flow director modes on x550.
46 * One is MAC VLAN mode, the other is tunnel mode.
48 * **Added i40e vector RX/TX.**
50 * **Added i40e flow control support.**

62 * **Added fm10k VMDQ support.**
64 * **New NIC Boulder Rapid support.**
66 Boulder Rapid is a new NIC of Intel's fm10k family.
68 * **Enhanced support for the Chelsio CXGBE driver.**
70 * Added support for Jumbo Frames.
71 * Optimize forwarding performance for Chelsio T5 40GbE cards.
73 * **Added support for Mellanox ConnectX-4 adapters (mlx5).**
75 The mlx5 poll-mode driver implements support for Mellanox ConnectX-4 EN
76 and Mellanox ConnectX-4 Lx EN families of 10/25/40/50/100 Gb/s adapters.
78 Like mlx4, this PMD is only available for Linux and is disabled by default
79 due to external dependencies (libibverbs and libmlx5).
81 * **Enhanced support for virtio driver.**
83 * Virtio ring layout optimization (fixed avail ring)
87 * **Added vhost-user multiple queue support.**
89 * **Added port hotplug support to vmxnet3.**
91 * **Added port hotplug support to xenvirt.**
100 * **eal/linux: Fixed epoll timeout.**
102 Fixed issue where the ``rte_epoll_wait()`` function didn't return when the
103 underlying call to ``epoll_wait()`` timed out.
109 * **igb: Fixed IEEE1588 frame identification in I210.**
111 Fixed issue where the flag PKT_RX_IEEE1588_PTP was not being set
112 in Intel I210 NIC, as EtherType in RX descriptor is in bits 8:10 of
113 Packet Type and not in the default bits 0:2.
115 * **ixgbe: Fixed issue with X550 DCB.**
117 Fixed a DCB issue with x550 where for 8 TCs (Traffic Classes), if a packet
118 with user priority 6 or 7 was injected to the NIC, then the NIC would only
119 put 3 packets into the queue. There was also a similar issue for 4 TCs.
121 * **ixgbe: Removed burst size restriction of vector RX.**
123 Fixed issue where a burst size less than 32 didn't receive anything.
125 * **i40e: Fixed base driver allocation when not using first numa node.**
127 Fixed i40e issue that occurred when a DPDK application didn't initialize
128 ports if memory wasn't available on socket 0.
130 * **i40e: Fixed maximum of 64 queues per port.**
132 Fixed the issue in i40e of cannot supporting more than 64 queues per port,
133 though hardware actually supports that. The real number of queues may vary,
134 as long as the total number of queues used in PF, VFs, VMDq and FD does not
135 exceeds the hardware maximum.
137 * **vhost: Fixed Qemu shutdown.**
139 Fixed issue with libvirt ``virsh destroy`` not killing the VM.
141 * **virtio: Fixed crash after changing link state.**
143 Fixed io permission in the interrupt handler.
145 * **virtio: Fixed crash when releasing queue.**
147 Fixed issue when releasing null control queue.
149 * **hash: Fixed thread scaling by reducing contention.**
151 Fixed issue in hash library where, using multiple cores with
152 hardware transactional memory support, thread scaling did not work,
153 due to the global ring that is shared by all cores.
158 * **hash: Fixed memory allocation of Cuckoo Hash key table.**
160 Fixed issue where an incorrect Cuckoo Hash key table size could be
161 calculated limiting the size to 4GB.
179 * The deprecated flow director API is removed.
180 It was replaced by rte_eth_dev_filter_ctrl().
182 * The dcb_queue is renamed to dcb_tc in following dcb configuration
183 structures: rte_eth_dcb_rx_conf, rte_eth_dcb_tx_conf,
184 rte_eth_vmdq_dcb_conf, rte_eth_vmdq_dcb_tx_conf.
186 * The function rte_eal_pci_close_one() is removed.
187 It was replaced by rte_eal_pci_detach().

195 rte_kni_create(), rte_kni_get_port_id() and rte_kni_info_get().
197 * The deprecated ring PMD functions are removed:
198 rte_eth_ring_pair_create() and rte_eth_ring_pair_attach().
200 * The devargs union field virtual is renamed to virt for C++ compatibility.
206 * The EAL and ethdev structures rte_intr_handle and rte_eth_conf were changed
207 to support Rx interrupt. It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
209 * The ethdev flow director entries for SCTP were changed.
210 It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
212 * The size of the ethdev structure rte_eth_hash_filter_info is changed
213 by adding a new element rte_eth_input_set_conf in an union.
215 * The new fields rx_desc_lim and tx_desc_lim are added into rte_eth_dev_info
218 * The maximum number of queues per port CONFIG_RTE_MAX_QUEUES_PER_PORT is
221 * The mbuf structure was changed to support unified packet type.
222 It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
224 * The dummy malloc library is removed. The content was moved into EAL in 2.1.
226 * The LPM structure is changed. The deprecated field mem_location is removed.
228 * librte_table LPM: A new parameter to hold the table name will be added to
229 the LPM table parameter structure.
231 * librte_port: Macros to access the packet meta-data stored within the packet
232 buffer has been adjusted to cover the packet mbuf structure.
234 * librte_cfgfile: Allow longer names and values by increasing the constants
235 CFG_NAME_LEN and CFG_VALUE_LEN to 64 and 256 respectively.
