A new function ``rte_pktmbuf_alloc_bulk()`` has been added to allow the user
to allocate a bulk of mbufs.
+* **Restored vmxnet3 Tx data ring.**
+
+ Tx data ring has been shown to improve small pkt forwarding performance
+ on vSphere environment.
+
+* **Added vmxnet3 Tx L4 checksum offload.**
+
+ Support TCP/UDP checksum offload.
+
+* **Added vmxnet3 TSO support.**
+
+* **Added vmxnet3 support for jumbo frames.**
+
+ Added support for linking multi-segment buffers together to
+ handle Jumbo packets.
+
* **Virtio 1.0.**
Enabled virtio 1.0 support for virtio pmd driver.
* **Added vhost-user live migration support.**
+* **Added multicast promiscuous mode support on VF for ixgbe.**
+
+ Added multicast promiscuous mode support on ixgbe VF driver. So all the VFs
+ can receive the multicast packets.
+
+ Please note if we want to use this promiscuous mode, we need both PF and VF
+ driver to support it. The reason is this VF feature is configured on PF.
+ If use kernel PF driver + dpdk VF driver, make sure kernel PF driver support
+ VF multicast promiscuous mode. If use dpdk PF + dpdk VF, better make sure PF
+ driver is the same version as VF.
+
* **Added support for E-tag on X550.**
E-tag is defined in 802.1br. Please reference
Only x550em_x V1 was supported before. Now V2 is supported.
A mask for V1 and V2 is defined and used to support both.
+* **Supported link speed auto-negotiation on X550EM_X**
+
+ Normally the auto-negotiation is supported by FW. SW need not care about
+ that. But on x550em_x, FW doesn't support auto-neg. As the ports of x550em_x
+ are 10G, if we connect the port with a peer which is 1G, the link will always
+ be down.
+ We added the support of auto-neg by SW to avoid this link down issue.
+
* **Added sw-firmware sync on X550EM_a.**
Added support for sw-firmware sync for resource sharing.
Use the PHY token, shared between sw-fw for PHY access on X550EM_a.
+* **Updated the i40e base driver.**
+
+ The i40e base driver was updated with changes including the
+ following:
+
+ * Use Rx control AQ commands to read/write Rx control registers.
+ * Add new X722 device IDs, and removed X710 one was never used.
+ * Expose registers for HASH/FD input set configuring.
+
* **Enabled PCI extended tag for i40e.**
It enabled extended tag by checking and writing corresponding PCI config
space bytes, to boost the performance. In the meanwhile, it deprecated the
legacy way via reading/writing sysfile supported by kernel module igb_uio.
+* **Added i40e support for setting mac addresses.**
+
+* **Added dump of i40e registers and EEPROM.**
+
* **Supported ether type setting of single and double VLAN for i40e**
+* **Added VMDQ DCB mode in i40e.**
+
+ Added support for DCB in VMDQ mode to i40e driver.
+
+* **Added i40e VEB switching support.**
+
+* **Added fm10k Rx interrupt support.**
+
+* **Optimized fm10k Tx.**
+
+ * Free multiple mbufs at a time to reduce freeing mbuf cycles.
+
+* **Handled error flags in fm10k vector Rx.**
+
+ Parse err flags in Rx desc and set error bits in mbuf with vector instructions.
+
+* **Added fm10k FTAG based forwarding support.**
+
+* **Added mlx5 flow director support.**
+
+ Added flow director support (RTE_FDIR_MODE_PERFECT and
+ RTE_FDIR_MODE_PERFECT_MAC_VLAN).
+
+ Only available with Mellanox OFED >= 3.2.
+
+* **Added mlx5 RX VLAN stripping support.**
+
+ Added support for RX VLAN stripping.
+
+ Only available with Mellanox OFED >= 3.2.
+
+* **Changed szedata2 type of driver from vdev to pdev.**
+
+ Previously szedata2 device had to be added by ``--vdev`` option.
+ Now szedata2 PMD recognises the device automatically during EAL
+ initialization.
+
+* **Added szedata2 functions for setting link up/down.**
+
+* **Added szedata2 promiscuous and allmulticast modes.**
+
+* **Added af_packet dynamic removal function.**
+
+ Af_packet device can now be detached using API, like other PMD devices.
+
* **Increased number of next hops for LPM IPv4 to 2^24.**
The next_hop field is extended from 8 bits to 24 bits for IPv4.
Added new Crypto PMD to support null crypto operations in SW.
+* **Improved IP Pipeline Application.**
+
+ The following features have been added to ip_pipeline application;
+
+ * Added CPU utilization measurement and idle cycle rate computation.
+ * Added link idenfication support through existing port-mask option or by
+ specifying PCI device in every LINK section in the configuration file.
+ * Added load balancing support in passthrough pipeline.
+
* **Added IPsec security gateway example.**
New application implementing an IPsec Security Gateway.
The driver now set the MDIO clock speed prior to initializing PHY ops and
again after the MAC reset.
+* **i40e: Generated MAC address for each VFs.**
+
+ It generates a MAC address for each VFs during PF host initialization,
+ and keeps the VF MAC address the same among different VF launch.
+
+* **i40e: Fixed failure of reading/writing Rx control registers.**
+
+ Fixed i40e issue of failing to read/write rx control registers when
+ under stress with traffic, which might result in application launch
+ failure.
+
+* **mlx5: Fixed possible crash during initialization.**
+
+ A crash could occur when failing to allocate private device context.
+
+* **mlx5: Added port type check.**
+
+ Done to prevent port initialization on non-Ethernet link layers and
+ to report an error.
+
+* **mlx5: Applied VLAN filtering to broadcast and IPv6 multicast flows.**
+
+ Prevented reception of multicast frames outside of configured VLANs.
+
+* **mlx5: Fixed RX checksum offload in non L3/L4 packets.**
+
+ Fixed report of bad checksum for packets of unknown type.
+
* **aesni_mb: Fixed wrong return value when creating a device.**
cryptodev_aesni_mb_init() was returning the device id of the device created,
Fix crc32c hash functions to return a valid crc32c value for data lengths
not multiple of 4 bytes.
+* **librte_port: Fixed segmentation fault for ring and ethdev writer nodrop.**
+
+ Fixed core dump issue on txq and swq when dropless is set to yes.
+
Examples
~~~~~~~~
+* **l3fwd-power: Fixed memory leak for non-IP packet.**
+
+ Fixed issue in l3fwd-power where, on receiving packets of types
+ other than IPv4 or IPv6, the mbuf was not released, and caused
+ a memory leak.
+
* **examples/vhost: Fixed frequent mbuf allocation failure.**
vhost-switch often fails to allocate mbuf when dequeue from vring because it
* A parameter ``vlan_type`` has been added to the function
``rte_eth_dev_set_vlan_ether_type``.
+* AF_packet device init function is no longer public. Device should be attached
+ with API.
+
* The LPM ``next_hop`` field is extended from 8 bits to 24 bits for IPv4
while keeping ABI compatibility.
