Subject: [PATCH] net: hns3: fix miss L3E checking for rx packet
For device supports RXD advanced layout, the driver will
return directly if the hardware finish the checksum
calculate. It cause missing L3E checking for ip packets.
Fixes it.
Fixes: 1ddc028ac849 ("net: hns3: refactor out RX completion checksum")
