ethtool: set netdev features with FEATURES_SET request
Implement FEATURES_SET netlink request to set network device features.
These are traditionally set using ETHTOOL_SFEATURES ioctl request.
Actual change is subject to netdev_change_features() sanity checks so that
it can differ from what was requested. Unlike with most other SET requests,
in addition to error code and optional extack, kernel provides an optional
reply message (ETHTOOL_MSG_FEATURES_SET_REPLY) in the same format but with
different semantics: information about difference between user request and
actual result and difference between old and new state of dev->features.
This reply message can be suppressed by setting ETHTOOL_FLAG_OMIT_REPLY
flag in request header.
