Subject: [PATCH v2] net/ice: fix DCF state checking mechanism
Date: Wed, 11 May 2022 15:49:30 +0000
Message-ID: <20220511154930.509436-1-peng1x.zhang@intel.com> (raw)

From: Peng Zhang <peng1x.zhang@intel.com>

DCF state previous checking mechanism can not fully detect DCF state
whether is on or not,so PMD will report uncorrect error code in some
cases and mislead user.Fix DCF state checking mechanism which will
mention user resource temporarily unavailable when DCF state is not on.

Fixes: 285f63fc6bb7 ("net/ice: track DCF state of PF")
Cc: stable@dpdk.org
