Merge branch 'virtio_net_ethtool_settings'
Nikolay Aleksandrov says:
====================
virtio_net: add ethtool get/set settings support
Patch 1 adds ethtool speed/duplex validation functions which check if the
value is defined. Patch 2 adds support for ethtool (get|set)_settings and
uses the validation functions to check the user-supplied values.
v2: split in 2 patches to allow everyone to make use of the validation
functions and allow virtio_net devices to be half duplex
v3: added a check to return error if the user tries to change anything else
besides duplex/speed as per Michael's comment
v4: Set port type to PORT_OTHER
v5: clear diff1.port (ignore port) when checking for changes since we set
it now and ethtool uses it in the set request
Sorry about the pointless iterations, should've all covered now.
