Subject: [PATCH v4 0/7] via-velocity performance fixes

Hi again!

This is version four of the series posted here:

   http://marc.info/?l=linux-netdev&m=125873023117769&w=2

The new version integrates Davids comments. There are 7 patches:

1. See to it that data is 64-byte aligned (same as before)

2. Add ethtool interrupt coalescing support. (same as before)

3. NAPI support for via-velocity (same as before)

4. Change DMA length default (same as before)

5. Re-enable scatter-gather support. (removed the double-check of
   nr_frags according to Davids comment)

6. Set tx checksum from ethtool instead of a module parameter (rebased)

7. Bump the version.

To get the same performance results (or better!) as with the VIA
driver, you now need to setup interrupt supression with

   ethtool -C ethX rx-usecs 20 tx-usecs 100 tx-frames 31 rx-frames 31

(which are the defaults from the VIA driver). Scatter-gather support is
enabled with

   ethtool -K ethX sg on
