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.
Found by coccinelle.

I tested this against Linux-4.19-rc4, and it seemed to work OK.
Please remove the irrelevant line 'Found by coccinelle.' from the
commit message. With that change:
