The reason sky2 driver was locking up on transmit on the Yukon-FE chipset
is that it was misconfiguring the internal RAM buffer so the transmitter
and receiver were sharing the same space.
The code assumed there was 16K of RAM on Yukon-FE (taken from vendor driver
sk98lin which is even more f*cked up on this). Then it assigned based on that.
The giveaway was that the registers would only hold 9bits so both RX/TX
had 0..1ff for space. It is a wonder it worked at all!
This patch addresses this, and fixes an easily reproducible hang on Transmit.
Only the Yukon-FE chip is Marvell 88E803X (10/100 only) are affected.

This patch works great - without it, I get only a few minutes of use
from my home dir over NFS4 before the NIC stops transmitting. This is
on a recent Yonah Sony VGN-SZ notebook w/ 88E8036 Marvel Sk-Y2.
Thanks again Stephen!
