Cleanup and harden the routines accessing the EEPROM.
  1. Prevent spin forever waiting for the TWSI bus
  2. Fix write eeprom to write full words rather than only 16 bits
    Luckly the vendor doesn't provide EEPROM in Linux format so it must never
    have been used.
  3. Don't allow partial eeprom writes, not needed, not safe.

These are non-urgent bug fixes.

This change makes it so only one srrctl register is programmed per VMDq id, and if VMDq is not enabled it is one register per RSS queue.  Currently this function is working correctly for the multiqueue RSS and single queue cases, but if any advances features such as VMDq or DCB would have been enabled this function would have caused issues as it was not correct.

the driver was misinterpreting rx_csum return value in the descriptor
so occassionally we would indicate an rx_csum error in our stats
when there was none.  This would have no effect on traffic because
we would just hand the packet to the stack anyway without the offload
flag set, but would increase CPU for those packets that needed a recompute.
