[PATCH 2/4] net/nfp: do not set the IPv6 flag in transport mode

[Chaoyong He]

From: Shihong Wang <shihong.w...@corigine.com>

The transport only encapsulates the security protocol header,
does not pay attention to the IP protocol type, and need not
to set the IPv6 flag.

Fixes: 3d21da66c06b ("net/nfp: create security session")
