Re: [PATCH 19.07] ipq40xx: Revert "ipq40xx: fix ethernet vlan double tagging"
I added a kernel flag to differentiate between both driver versions. https://github.com/openwrt/openwrt/pull/3596 I would backport this to 19.07 if it gets accepted.

[PATCH 19.07] ipq40xx: Revert "ipq40xx: fix ethernet vlan double tagging"
From: Baptiste Jonglez This change has been causing several issues on ipq40xx devices, including: - VLAN tagging no longer works correctly: https://bugs.openwrt.org/index.php?do=details_id=3239 - poor performance with tagged VLANs: https://bugs.openwrt.org/index.php?do=details_id=3457 See also https://forum.openwrt.org/t/vlan-tagging-on-ipq40xx-gl-b1300-no-longer-works/69569 There are have been discussions on ways to fix the issue in the links above (including switching to DSA), but nothing that can realistically be introduced in the 19.07 branch. This reverts commit 8c191712558ce94 ("ipq40xx: fix ethernet vlan double tagging") Note that it's not a clean revert because this patch was touched in 148d59c67edd5 ("kernel: update kernel 4.14 to version 4.14.193") even though the semantic of the patch was left unchanged.
