FS#3454 - Netgear WNDR3800 VLAN switch broken 19.07.4

Supply the following if possible:
- Device problem occurs on
- Software versions of OpenWrt/LEDE release, packages, etc.
- Steps to reproduce


With the latest release of OpenWrt (19.07.4) using a VLAN > 16 fails. It’s rather strange as this was a problem years ago with the RTL8366s switch on these devices. I verified the firmware is reporting itself as 19.07.4 (I wondered if the files got mixed up and I was using some 18.xx version due to issues with the download site, but that is not the case).

As long as the VLAN/VID are below 16 everything works properly, but for a VLAN > 16 (regardless of whether one keeps the VLAN ⇐ 16 and only sets the VID to the actual VLAN (e.g. to match a switch into which the WNDR3800 is plugged).
For now I’ve just been disabling the switch and configuring software VLAN and letting the other switch sort out tagging/untagging.

I did some experimenting and it looks like the switch config has had some kind of weird regression.

I don’t have a spare device (and am not set up for developing / building OpenWrt at the moment), so this is more of placeholder bug until someone with resources (device / time / etc) can work on it.

On a separate note: is GitHub login deliberately disabled, or is it only me that’s having logging in with GitHub – basically is this deliberate/known or should I file a separate bug for that?

It's still a problem on 19.07.5. I think using the now mainlained rtl8366s driver may be the issue as it probably doesn't have some of the fixes that were in OpenWrt for that switch. Not sure too many people besides me are still using ath79 devices these days though, so it'll probably die from neglect (especially since once I can, I plan on replacing it rather than fighting with it).
