[dpdk-dev] [PATCH] net/mlx5: fix legacy non inline multi packet session

[Viacheslav Ovsiienko]

The commit being fixed introduced the different format
for the transmitting descriptor multi-packet session for
ConnectX-4LX. The session was assumed always opened if
not-inlinable packet was encountered. The patch checks
whether the inline multi-packet is opened and it allows
to proceed with normal packets (non inlined) successfully.

Fixes: 82a506b404b0 ("net/mlx5: fix the legacy multi packet write session")
