[PATCH] S2io: Hardware fixes for Xframe II adapter 

Hi,

Patch Description:
This patch incorporates the following hardware fixes required
for Xframe II adapter.
1. New values to program the dtx_control register.
2. Disable memory controller interrupts(MC_INTR) since these
   are now monitored thru' a poll routine.
3. Don't reset an XframeII card on an ECC double-bit error(It
   can recover).
4. Save/restore PCI config space before/after a reset irrespective
   of Xframe I or II card.
5. Bumped up the driver version no. to 2.0.3.1

Please review the patch and apply the same if it looks ok.
