From: Harshal Gohel Date: Wed, 3 Jan 2024 14:53:47 +0000 (+0100) Subject: rtl93xx: dsa: Fix 802.1QinQ for trunk ports X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=da495c477d9018d59b1f6deb128cc8372d16df16;p=openwrt%2Fstaging%2Fnbd.git rtl93xx: dsa: Fix 802.1QinQ for trunk ports Fix incorrect register value being set for VLAN_PORT_FWD Before, the 0b1111 would be set for the register which means outgoing packets would receive an extra tag, corresponding to the PVID of the port. On untagged ports, this meant outgoing packets with a single tag. On tagged ports, this meant outgoing QinQ packets, where the inner tag was either the PVID of the untagged ingress port, or the already assigned original (single) tag.
