Subject: [Enable Designware XGMAC VLAN Stripping Feature 1/2] dt-bindings: net: snps,dwmac: Add description for rx-vlan-offload

From: Boon Khai Ng <boon.khai.ng@...el.com>

This patch is to add the dts setting for the MAC controller on
synopsys 10G Ethernet MAC which allow the 10G MAC to turn on
hardware accelerated VLAN stripping. Once the hardware accelerated
VLAN stripping is turn on, the VLAN tag will be stripped by the
10G Ethernet MAC.
