[PATCH] S2io: Hardware fixes
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.
