I just brought two D-Link DGE-528T (uses r8159 driver) network adapters
to have nice 1 Gbps home network between two computers.

- which kernel ?
- dmesg please ?

[...]

and when I use this cable I only get 10 Mbps connection when connected
another D-Link DGE-528T.

Try a straight cable between the two D-Link adapters.

[...]

Do anyone know if there some known bug in auto-negotiation with
Realtek 8159 chip? (Or is that just wrong cable?)

Can I force 1000 Mbps link on some other way than giving option to
insmod? Using /proc or something?

mii-tool or (better) ethtool.

[...]

What kind of transfer speed you have reached with these cards ? That
15 MiB/s is not what I expected.

It smells like fast ethernet. Even my old PII does better than that with
a 8169.

Please send 'mii-tool -vv' and/or ethtool output + vmstat 1 during test.
