Subject: net/mlx5: fix TSO TCP checksum flag
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=2a6c96be134178583b707e68c9297820aaee088b;p=dpdk.git

net/mlx5: fix TSO TCP checksum flag

Since PKT_TX_TCP_SEG implies PKT_TX_TCP_CKSUM, the PMD must force this
flag.
The fix applied for both tunneled and non-tunneled packets.

Fixes: 3f13f8c23a7c ("net/mlx5: support hardware TSO")
Fixes: b247f346019b ("net/mlx5: support hardware TSO for VXLAN and GRE")
