The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, but the implementation in this
driver returns an 'int'.

Fix this by returning 'netdev_tx_t' in this driver too.

It was applied already but there should be also kernel-doc update too to
use enum values instead of 0.

I can squash in that change.
