[dpdk-dev] [PATCH] net/ice: fix RSS for GTPU

Qi Zhang qi.z.zhang at intel.com
Wed May 13 14:11:44 CEST 2020


All supported pattern for GTPU include extend header:
pattern_eth_ipv4_gtpu_eh_ipv4
pattern_eth_ipv4_gtpu_eh_ipv4_udp
pattern_eth_ipv4_gtpu_eh_ipv4_tcp

So the RSS rule should only take effect on GTPU packet that contains
extend header. The patch fix above issue and also allow inner l4 port
as input set.

Fixes: c08a72c79c7f ("net/ice: fix pattern name of GTPU with extension header")
