you should get the ret value of vpls_rcv() and increment stats if error
occurs.

An error in vpls_rcv() is not a receive error on the outer device's MPLS
layer;  the packet was received correctly (and counted for that at the
beginning of mpls_forward()) and dispatched onto an appropriately
configured VPLS device.  vpls_rcv() counts its own stats on the inner
device.

Right.
