Subject: [dpdk-dev] [PATCH] net/mlx5: fix legacy non inline multi packet session
Date: Wed, 12 Feb 2020 17:49:08 +0000 [thread overview]
Message-ID: <1581529748-21677-1-git-send-email-viacheslavo@mellanox.com> (raw)
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")
