-Subject: [PATCH] net/mlx5: add hardware checksum offload for tunnel packets
-
-Prior to this commit Tx checksum offload was supported only for the
-inner headers.
-This commit adds support for the hardware to compute the checksum for the
-outer headers as well.
-
-The support is for tunneling protocols GRE and VXLAN.

-Subject: [PATCH] net/mlx5: add enhanced multi-packet send for ConnectX-5
-
-ConnectX-5 supports enhanced version of multi-packet send (MPS). An MPS Tx
-descriptor can carry multiple packets either by including pointers of
-packets or by inlining packets. Inlining packet data can be helpful to
-better utilize PCIe bandwidth. In addition, Enhanced MPS supports hybrid
-mode - mixing inlined packets and pointers in a descriptor. This feature is
-enabled by default if supported by HW.
