[dpdk-dev] [PATCH] net/ice: fix GTPU/PPPoE packets with no hash value

[Simei Su]

When RSS init, because of profile overlap, the GTPU_IPV4 packets
don't hit GTPU_INNER_IPV4 profile which causes no hash value. Because
of no PPPoE profile, the PPPoE packets also has no hash value. This
patch solves this issue by pulling GTPU_IPV4 profile into inner ipv4
group and creating related PPPoE profile at the same time.

Fixes: 8cadc41294c6 ("net/ice: initialize and update RSS based on user config")
