[PATCH AUTOSEL 5.19 27/73] net: sunplus: Fix return type for implementation of ndo_start_xmit

From: GUO Zihua <redacted>

[ Upstream commit 7b620e156097028e4c9b6481a84ec1e1e72877ca ]

Since Linux now supports CFI, it will be a good idea to fix mismatched
return type for implementation of hooks. Otherwise this might get
cought out by CFI and cause a panic.

spl2sw_ethernet_start_xmit() would return either NETDEV_TX_BUSY or
NETDEV_TX_OK, so change the return type to netdev_tx_t directly.
