Subject: [dpdk-stable] [PATCH] net/e1000: fix link status
Date: Wed, 13 Nov 2019 12:46:59 +0000
Message-ID: <20191113124659.88561-1-lunyuanx.cui@intel.com> (raw)

The link status got from link status register was not correct,
because register has been reset when ports reset.
After port reset, set the link status down.

Fixes: c431ec66c54c ("net/igb: support setting link up or down")
Cc: stable@dpdk.org
