With the ethtool_virtdev_set_link_ksettings function in core/ethtool.c,
ibmveth, netvsc, and virtio now use the core's helper function.
Funtionality changes that pertain to ibmveth driver include:
1. Changed the initial hardcoded link speed to 1GB.
2. Added support for allowing a user to change the reported link
speed via ethtool.
Functionality changes to the netvsc driver include:
1. When netvsc_get_link_ksettings is called, it will defer to the VF
device if it exists to pull accelerated networking values, otherwise
pull default or user-defined values.
2. Similarly, if netvsc_set_link_ksettings called and a VF device
exists, the real values of speed and duplex are changed.
