So, RX-ALL can be one flag, another for RX-FCS, and the TX-CUSTOM-FCS
can be a separate patch altogether?

It would also be possible to add individual 'rx-foo', ie long, bad-crc, bad-frame, etc.
But, I think that would probably be over-kill at this point.

Any problem with using the netdev->priv_flags to hold the RX-ALL and RX-FCS flags?

Btw, it's impossible (afaik) to see the CRC errors generically w/out accessing netlink
(which I assume works, but have never actually tried), ie
there is no column in /proc/net/dev for rx-crc-errors.  It would be an excellent
time to allow me to add the ethtool hook to read the net_device_stats struct via
a single ioctl call! :)


Thanks,
Ben
