ethtool: provide link mode information with LINKMODES_GET request
Implement LINKMODES_GET netlink request to get link modes related information provided by ETHTOOL_GLINKSETTINGS and ETHTOOL_GSET ioctl commands. This request provides supported, advertised and peer advertised link modes, autonegotiation flag, speed and duplex. LINKMODES_GET request can be used with NLM_F_DUMP (without device identification) to request the information for all devices in current network namespace providing the data.
