From 9c9b1febff6863ccd3632a04d9e307909b3efe7a Mon Sep 17 00:00:00 2001 From: Christian Breunig Date: Wed, 20 Mar 2024 21:25:43 +0100 Subject: bridge: T6125: support 802.1ad (ethertype 0x88a8) VLAN filtering Linux bridge uses EtherType 0x8100 by default. In some scenarios, an EtherType value of 0x88A8 is required.
