commit 8b3823ce30a3e57249fe7f329896f146e6eb920d
Author: Patrick McHardy <kaber@trash.net>

net: convert remaining non-symbolic return values in ndo_start_xmit() functions
This patch converts the remaining occurences of raw return values to their
symbolic counterparts in ndo_start_xmit() functions that were missed by the
previous automatic conversion.
Additionally code that assumed the symbolic value of NETDEV_TX_OK to be zero
is changed to explicitly use NETDEV_TX_OK.
