[dpdk-dev] [PATCH RFC 2/2] net/ice: support drop any and steer all to queue

[Yuying Zhang]

This patch supports drop any and steer all to queue in switch
filter. Support new rte_flow pattern any to handle all packets.
The usage is listed below.

1. drop any:
flow create 0 ingress pattern any / end actions drop / end
All packets received in port 0 will be dropped.

2. steer all to queue:
flow create 0 ingress pattern any / end actions queue index 3 / end
All packets received in port 0 will be steered to queue 3.
