Subject: [PATCH] net: atl*: convert to hw_features
Things left as they were:
- atl1: is RX checksum really enabled?
- atl2: copy-paste from atl1, with-errors-on-modify I presume
- atl1c: there's a bug: MTU can't be changed if device is not up
Signed-off-by: Michał Mirosław <mirq-linux@...e.qmqm.pl>
