Subject: [dpdk-dev] [PATCH] net/i40e: fix FDIR issue for ETH + VLAN pattern
Date: Fri, 23 Oct 2020 16:15:09 +0800 [thread overview]
Message-ID: <20201023081509.13087-1-beilei.xing@intel.com> (raw)
From: Beilei Xing <beilei.xing@intel.com>
Currently, can't create more than one following flow for
ETH + VLAN pattern:
> flow create 0 ingress pattern eth / vlan vid is 350 / end
actions queue index 2 / end
The root cause is the keys of all such flows are the same.
Fixes: 42044b69c67d ("net/i40e: support input set selection for FDIR")
