Updated information on the bug, Guo-Fu Tseng says that might not be a
bug on the driver, but i've tested other network cards and they don't
share the same issue.
Also, on interesting update that people may consider is that after
running tcpdump on the device, the network starts working again.
Information are updated in the bug.

Hi Leonardo L. P. da Mata:
The value of register which holds receive Unicast MAC Address somehow
get messed-up after resume!

Guo-Fu Tseng
Hello Guo-Fu Tseng, not good news, the patch is not working.
But i've noticed one interesting behavior.
I've done 2 tests, on the first i've suspended, resumed and after
resume done a tcpdump. Only after the tcpdump, the network starts to
work.
ethtool-before
ethtool-before-d
ethtool-after
ethtool-after-d
ethtool-after-tcpdump
ethtool-after-tcpdump-d
on the second test, i've done the tcpdump befor suspending, and after
the resume the connection works.
ethtool-before-2
ethtool-before-2-d
ethtool-before-2-tcpdump
ethtool-before-2-tcpdump-d
ethtool-after-2-tcpdump
ethtool-after-2-tcpdump-d
I've attached the ethtool logs, and they are listed in the order of the steps.
i hope we can solve this mistery.
