Subject: [PATCH 05/19] net/txgbe: reconfigure more MAC Rx registers
Date: Tue, 18 Jun 2024 15:11:36 +0800	[thread overview]
Message-ID: <20240618071150.21564-6-jiawenwu@trustnetic.com> (raw)
In-Reply-To: <20240618071150.21564-1-jiawenwu@trustnetic.com>

When link status changes, there is a probability that no more packets can
be received on the port, due to hardware defects. These MAC Rx registers
should be reconfigured to fix this problem.

Fixes: 950a6954df13 ("net/txgbe: reconfigure MAC Rx when link update")
Cc: stable@dpdk.org
