Changes since yesterday's patch:

 - Make all methods take the struct net_device as suggested by Ben Greear.
 - Rename self_test_len() and get_stats_len() to *_count() to reflect
   that they return a count of elements, not a byte length.
 - Related bugfixes.
 - Remove the get_strings_len() method; we now infer the length from
   either self_test_count() or get_stats_count().
 - memset() the drvinfo struct so it doesn't leak information from the
   kernel stack (existing bug in tg3).
 - Clamp regs.len in ethtool.c rather than in the driver.
 - Pass the stringset value to get_strings() rather than a pointer to
   the whole ethtool_gstrings struct.

I have a question about the error return values in ethtool_get_strings().
Are -EOPNOTSUPP and -EINVAL the right ones to use in the case statement?
Or should I perhaps be using -ENOSYS instead of EINVAL?  I've noticed
drepper tends to prefer this for unimplemented subops.  Since this is
an ioctl(), perhaps I should be using -ENOTTY instead ;-)

Anyway, further comments welcomed.
