[Bug 1798921] Re: sky2 ethernet card don't work after returning from suspension

Sorry, didn't realize what was meant. I don't use WoL, only suspend
(manually or by closing the lid). Resume works for me with the 4.13
kernels Mint provided so far. All of the 4.15 kernels I tried so far
didn't work.

I've also filed
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1807259 for this
issue.

Title:
sky2 ethernet card don't work after returning from suspension

Status in linux package in Ubuntu:
Confirmed

Bug description:
Bug very similar to #1752772
(https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1752772) but
affecting the sky2 driver instead of r8169.

After system suspend the ethernet connection stops working. The card
is still up and the modem can see it is connected, but the card
doesn't get an ip address. Ifconfig down/up and restarting network-
manager does not solve the issue. Similarly to the other bug, "sudo
modprobe sky2 -r" an then "sudo modprobe sky2" solves the issue.
