I've been trying to migrate off sk98lin to skge since earlier this year,
without success, starting with 2.6.18 or .19.

I have several of these cards in production using the sk98lin driver:

fresno:~# lspci -vv -s 02:01
02:01.0 Ethernet controller: SysKonnect SK-9872 Gigabit Ethernet Server Adapter (SK-NET GE-ZX dual link) (rev 11)
Subsystem: SysKonnect SK-9844 Gigabit Ethernet Server Adapter (SK-NET GE-SX dual link)
Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV+ VGASnoop- ParErr- Stepping- SERR+ FastB2B-
Status: Cap+ 66MHz+ UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR-
Latency: 64 (5750ns min, 7750ns max), Cache Line Size: 32 bytes
Interrupt: pin A routed to IRQ 22
Region 0: Memory at febfc000 (32-bit, non-prefetchable) [size=16K]
Region 1: I/O ports at e800 [size=256]
Expansion ROM at febc0000 [disabled] [size=128K]
Capabilities: [48] Power Management version 1
Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-)
Status: D0 PME-Enable- DSel=0 DScale=1 PME-
Capabilities: [50] Vital Product Data

They are dual port SX fiber. Both ports are connected. If I do this:

fresno:~# modprobe skge
fresno:~# ip li set eth2 up
fresno:~# ip li set eth2 down
fresno:~# ip li set eth3 up

the system locks up and I have to power cycle it. The order doesn't
matter (if I do eth3 up/down, then eth2 up kills it).

I don't have any problems with sk98lin. This works fine:

fresno:~# modprobe sk98lin RlmtMode=DualNet
fresno:~# ip li set eth2 up
fresno:~# ip li set eth2 down
fresno:~# ip li set eth3 up
fresno:~# ip li set eth3 down

I am more than happy to test various driver changes, and have tried a few
suggested patches but nothing has worked so far. I would like to be using
skge instead of sk98lin, but so far haven't had any success.
