Subject: [dpdk-dev] [PATCH] net/i40e: fix register setting for hash enable
Date: Tue, 26 Jan 2021 17:52:11 +0800
Message-ID: <20210126095211.628354-1-dapengx.yu@intel.com> (raw)

From: Dapeng Yu <dapengx.yu@intel.com>

The original code causes wrong value to be set into PFQF_HENA
register because unnecessary calling to get translated pctype
value for X722 NIC. The result is RSS cannot work.

So remove the unnecessary translation.

Fixes: ef4c16fd9148 ("net/i40e: refactor RSS flow")
Cc: stable@dpdk.org
