Subject: [PATCH] 8139cp: properly config rx mode after resuming
|
|
|
|
Rx mode should be reset after resming, so unconditionally updating rx
|
|
mode rather than conditionally updating based on the value we
|
|
remembered, otherwise unexpected value may be used by the nic after
|
|
resuming.
|
|
|
|
btw. I find and test this when debugging guest hibernation in qemu, as
|
|
I did not have a 8139cp card in hand, this patch is untested in a
|
|
physical 8139cp card, plase review it carefully.
