ethtool_features?

[Jeff Garzik <jgarzik@xxxxxxxxx>]

Hum.  Instead of adding all these _get_foo ops to test dev->features 
bits, would anyone mind if I created a single _get_features() ethtool 
sub-ioctl?
Given the current ethtool_ops code, its implementation would in fact be 
completely transparent to low-level drivers.  It need only be 
implemented in net/core/ethtool.c, without even adding a new hook.
