      I have frequent link down trouble in our customer factory but can't re-produce in our bench.

      The frequent link down port uses the 82579 nic and I found out the below issue.

       

      kernel/git/torvalds/linux.git - Linux kernel source tree

       

      It seems the relaxation of link down condition, but can't understand detail work around.

      The modifed registers lost in 82579's specification, So, please share the information.

       

      * MSE
