[PATCH 4.19 131/243] can: xilinx: fix return type of ndo_start_xmit function

[Greg Kroah-Hartman]

From: YueHaibing <yuehaibing@xxxxxxxxxx>

[ Upstream commit 81de0cd60fd492575b24d97667f38b8b833fb058 ]

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.
