Possible sge(4)/atphy(4) regression on RELENG_9?

[Nikolay Denev]

Hello,

I've recently upgraded a box running RELENG_8 to RELENG_9 and immediately I noticed much slower network connection.
Running iperf shows about 20-30Mbits which was almost full GigE (~900Mbits) speed before.

I'm noticing interface errors :

[16:37]ndenev at nas:~% netstat -I sge0
Name    Mtu Network       Address              Ipkts Ierrs Idrop    Opkts Oerrs  Coll
sge0   1500 <Link#4>      00:0a:e4:86:62:fa 76114295 42197     0 103559806 10324     0
sge0   1500 10.0.0.0      nas               76109575     -     - 119109557     -     -

Both the switch and the card show 1000 full-duplex.
I've tried playing with rxcsum,txcsum,vlanhwtag,tso but disabling even all of them do not change anything.
I've tried different switch port and changed the cable.

Here is devinfo for my hardware :

sge0 pnpinfo vendor=0x1039 device=0x0191 subvendor=0x103c subdevice=0x2a70 class=0x020000
atphy0 pnpinfo oui=0xc82e model=0x1 rev=0x6 at phyno=0

Of course all of this can mean hardware problem, I just want to ask if somebody is seeing something similar, since
there are quite a lot minibus related changes as far as I can see.

I'll boot RELENG_8 again tomorrow and do a quick test again to verify that this is not a hardware issue.
