[PATCH v5 07/12] net/i40e: fix IPv6 GTPU handling

[Anatoly Burakov]

GTP tunnel code declares support for IPv6 GTPU flows but does not actually
handle IPv6 flow pattern item, resulting in incorrect parsing for IPv6
GTPU flows. Add IPv6 flow item handling.

Fixes: 47ba0398da3f ("net/i40e: add cloud filter parsing function for GTP")
