Subject: [dpdk-dev] [PATCH v3] net/ixgbe: fix link status
Date: Mon, 18 Nov 2019 10:13:45 +0000	[thread overview]
Message-ID: <20191118101345.42181-1-lunyuanx.cui@intel.com> (raw)
In-Reply-To: <20191113163441.90162-1-lunyuanx.cui@intel.com>

After ports reset, tx laser register will be reset. The link
status for 82599eb got from link status register was not correct.
Set tx laser disable when port resets.

ixgbe_flap_tx_laser_multispeed_fiber() can cause link status
change from down to up. This treatment should work after
port starts.

Fixes: 0408f47ba4d6 ("net/ixgbe: fix busy polling while fiber link update")
