The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, so make sure the implementation in
this driver has returns 'netdev_tx_t' value, and change the function
return type to netdev_tx_t.

I would advise you not to send so many of these changes as a group.

If one of the patches needs feedback addressed, which is already the
case, you will have to resubmit the entire series all over again with
the fixes.
