eepro100 timeout error, bug.

[Soohoon Lee]

> I'm having troble with eepro100 on 2.3.99-prex.
> It generates timeout error very often.
> I thought it is alpha platform problem but it's new driver's bug.
> There's a race condition problem in speedo_start_xmit().
> The driver does read-modify-write and mean while 8255x write something
> to the same address. So I change the operation automic.
> Old driver(in 2.2.14) doesn't have the problem.
> What about seperating one 4bytes field to two 2byte fields.
