[PATCH] S2io: Software fixes

Hi,
Below patch includes fixes for few purely software bugs identified
since last release.
1. Keep track and display(as part of ethtool command output) the no.
   of single-bit and double-bit ECC errors.
2. Handle race condition between intr handler and "interface down"
   routine.
3. Initial link state setting modified so that the link state displayed
   after "interface Up" is correct.
4. Fix for "Incorrect Tx packet count when TSO is enabled".
5. Disable periodic DMA of statistics and schedule one-shot DMA
   only when required.
