Subject: [PATCH 5.15 33/73] net: lantiq_xrx200: fix statistics of received bytes

From: Aleksander Jan Bajkowski <olek2@...pl>

[ Upstream commit 5be60a945329d82f06fc755a43eeefbfc5f77d72 ]

Received frames have FCS truncated. There is no need
to subtract FCS length from the statistics.

Fixes: fe1a56420cf2 ("net: lantiq: Add Lantiq / Intel VRX200 Ethernet driver")
