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
what of MSE? how condition leads link down?
* original valule
please share the threshold and counter's original values and meenings.
Thanks,
