Subject: [dpdk-dev] [PATCH] net/ixgbe: fix ixgbevf link status
Date: Tue, 17 Dec 2019 06:12:03 +0000	[thread overview]
Message-ID: <20191217061203.47833-1-lunyuanx.cui@intel.com> (raw)

The link status for ixgbevf is not correct when PF link up.
IXGBE_ESDP register is only used when media type is fiber.

Fixes: 1ca05831b9be ("net/ixgbe: fix link status")
Cc: stable@dpdk.org
