r8169 not advertising 1000mbit after suspend anymore

[Benjamin S.]

Hello,

I have a Gigabyte GA-MA78G-DS3H mainboard with a RTL8111/8168B Realtek 
Gigabit Ethernet Controller. Until first suspend everything works as 
expected, but after suspend only 100mbit are used instead of 1000.

I did not knew if the Switch could be the problem and thus I connected the 
card to my laptop which also has a gigabit controller, but the result was 
the same as above.

Benjamin

Which kernel do you use ?

At which point it works correctly again, right ?

At least some 8168 appear to lose the link settings :o/

Please send the XID line of the offender taken from dmesg.

Yes. After resetting speed with ethtool file transfers with 25MB/s
between my router and my computer are possible again.
