Subject[PATCH AUTOSEL 4.19 042/191] net: xilinx: fix return type of ndo_start_xmit function
Date
From: YueHaibing <yuehaibing@huawei.com>

[ Upstream commit 81255af8d9d5565004792c295dde49344df450ca ]

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.
