netdev-linux: Cache error code from get-features.
		
Following patch adds support for caching error code from ETHTOOL_GSET
call. Since internal device is virtual device device feature does not
make much sense, so netdev_get_features op is removed for internal
devices.

netdev-linux: Cache error code from mtu ioctl.
		
netdev linux devices uses mtu ioctl to get and set MTU for a device.
By caching error code from ioctl we can reduce number of ioctl calls
for device which is unregistered from system.
netdev notification is used to update mtu which saves get-mtu-ioctl.

netdev-linux: Cache drv-info for net device.
		
Netdev-linux calls ETHTOOL_GDRVINFO on every netdev_linux_get_status()
which is not optimal as drv-info does not change for given device.
So following patch changes netdev_linux_get_status() to read drv-info at
device initialization and cache it.
