[PATCH] S2io: Hardware fixes

Browse Source 
Hi,
Below patch addresses few h/w specific issues.
1. Check for additional ownership bit on Rx path before
   starting Rx processing.
2. Enable only 4 PCCs(Per Context Controller) for Xframe I
   revisions less than 4.
3. Program Rx and Tx round robin registers depending on
   no. of rings/FIFOs.
4. Tx continous interrupts is now a loadable parameter.
5. Reset the card if we get double-bit ECC errors.
6. A soft reset of XGXS being done to force a link state change has been
   eliminated.
7. After a reset, clear "parity error detected" bit,
   PCI-X ECC status register, and PCI_STATUS bit in
   tx_pic_int register.
8. The error in the disabling allmulticast implementation has been
   rectified.
9. Leave the PCI-X parameters MMRBC, OST etc. at their
   BIOS/system defaults.
