[SC92031] Using padto turned driver into an IPv6-only interface
IPv4 would work with this driver only with static arp table entries,
the patch reverts a padto introduced in
commit 26a17b7bbb36a8552d531bc1ad08472fb5aa3007
sc92031: start transmit return value bugfix
The padto does not work because the driver code evaluates `len' later on and
there are cases where skb->len is not updated accordingly.
This was observed with ARP frames (skb->len = 42 bytes, !skb_cloned(),
skb_tailroom = 84 bytes). Then in skb_pad(), the first condition is true, where
skb->len is not updated. As a consequence, the driver uses 42 bytes instead of
the 60 bytes, and the ARP frame never makes it onto the wire.
