[dpdk-dev] [PATCH] net/ice: fix GTPU rule confliction

Wed Jan 22 06:28:24 CET 2020


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")
