  To: yahui.cao, beilei.xing; +Cc: chenmin.sun, dev, Qi Zhang, stable

The patch distinguish fdir rules for GTPU with or without
extend header, so flow to match below patterns can be created
correctly.

1. eth / ipv4 / udp / gtpu teid is 10 / ...
2. eth / ipv4 / udp / gtpu teid is 10 / gtp_psc / ...
3. eth / ipv4 / udp / gtpu / gtp_psc qfi is 10 / ...
4. eth / ipv4 / udp / gtpu teid is 10 / gtp_psc is 10 / ...

Fixes: efc16c621415 ("net/ice: support flow director GTPU tunnel")
Cc: stable@dev.org
