Subject: [dpdk-stable] [PATCH] net/ice: fix AdminQ handling on DCF passive reset
Date: Tue,  9 Nov 2021 15:49:47 +0800
Message-ID: <> (raw)

From: Dapeng Yu <>

DCF tries to handle AdminQ when DCF is reset by PF, however the invalid
data may be returned, and error log may be output in this situation.

This patch stops handling AdminQ when a passive reset is detected to
avoid this situation.

Fixes: 7564d5509611 ("net/ice: add DCF hardware initialization")
