[PATCH 4.19 279/422] net: sun: fix return type of ndo_start_xmit function

[Greg Kroah-Hartman]

From: YueHaibing <yuehaibing@xxxxxxxxxx>

[ Upstream commit 0e0cc31f6999df18bb5cfd0bd83c892ed5633975 ]

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, but the implementation in this
driver returns an 'int'.

Found by coccinelle.
