yongari nfe problems

[Rainer Hurling]

Thank you Pyun YongHyeon for the newest patch. I am running it with 
if_nfe.c and if_nfereg.h from 03/21/2007 and if_nfevar.h from 03/19/2007 
on FreeBSD 7.0-CURRENT (i386) from today.

boot -v gives me:
nfe0: <NVIDIA nForce MCP55 Networking Adapter> port 0xb000-0xb007 mem 
xfbef3000-0xfbef3fff,0xfbefa800-0xfbefa8ff,0
xfbefa400-0xfbefa40f irq 22 at device 8.0 on pci0
nfe0: Reserved 0x1000 bytes for rid 0x10 type 3 at 0xfbef3000
miibus0: <MII bus> on nfe0
ciphy0: <VSC8601 10/100/1000TX PHY> PHY 1 on miibus0
ciphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, 
1000baseT-FDX, auto
nfe0: bpf attached
nfe0: Ethernet address: 00:16:17:95:d9:7c
nfe0: [MPSAFE]
nfe0: [FILTER]


Now there are no more warning from miibus0 :-)

Unfortunately at bigger network transfers I still observe the previously 
described watchdog timeouts:

nfe0: watchdog timeout (missed Tx interrupts) -- recovering
nfe0: watchdog timeout (missed Tx interrupts) -- recovering
nfe0: watchdog timeout (missed Tx interrupts) -- recovering
nfe0: watchdog timeout (missed Tx interrupts) -- recovering
nfe0: watchdog timeout (missed Tx interrupts) -- recovering
nfe0: watchdog timeout (missed Tx interrupts) -- recovering
...

During these timeouts I am not able to use my network ;-(

I would be happy if I could help solving this problem. Let me know if I 
can test anything.

Thank you so long,
Rainer
