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.
+
* **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.
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.
+
* **aesni_mb: Fixed wrong return value when creating a device.**
cryptodev_aesni_mb_init() was returning the device id of the device created,
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
