hello,

I have issues transfering big or many files over ethernet on 1000H, also.
Using yongari's ale(4) driver
http://people.freebsd.org/~yongari/ale/ale.20081114.tar.gz I did not
have any problems while I surf or download 37MB sourcecode from inet.
Then scp(1)'ing source from 1000H to desktop PC showed a transfer rate
with maximum 86kB/s regardless to which direction is copied. The
ethernet NIC, while copying, is switched off regularily then. No
copies possible after three megabytes.

Try turning off TSO and let me know how it goes.
("#ifconfig ale0 -tso" will do the job.)

Next try was a big file. A packed tarball from the source-tree was
copied via nc(1) using TCP-protocol. After 7 until 17MB no transfer
possible and same symptoms like above.

One way I can reproduce this is the following:
on desktop PC: $> nc -4nl 1234 > bigfile.tar.gz
on 1000H: $> nc -4n 192.x.x.x 1234 < bigfile.tar.gz
It makes no difference wether I am a user or root. Tested over a
switch and a crossover cable.
Does anybody has a hint?

best regards.

As this is my first post, I try to attach my kernelconfig and two
sysctl dev.ale.0 (before and after error).

- dmesg shows:

This would be major reason why you're getting poor performance.

10 ale0: could not disable Tx/Rx MAC(0x00000008)!
11 ale0: link state changed to DOWN
12 ale0: link state changed to UP
13 ale0: link state changed to DOWN
14 ale0: link state changed to UP

17 ale0: could not disable Tx/Rx MAC(0x00000008)!
18 ale0: link state changed to DOWN
19 ale0: link state changed to UP

- ifconfig shows:
1 ale0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
2 options=319b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4>

It seems that your hardware doesn't have WOL capability. But I
guess EeePC 1000H does support WOL. You've disabled some
functionality of ethernet controller in BIOS?
