@qosmio - TL;DR: is there any chance that any of your NSS-related commits from the past few weeks would cause WAN to break if your ISP doesnt provide ip6 and only uses ip4?
so, Im now on rebuild number 6 or 7 and all of them have had no WAN connectivity, no matter what I try. Even setting it to use the same static address that it was previously assigned via DHCP from my ISP doesnt work. Everything else works perfectly, but nothing on WAN. ifconfig can bring wan UP and DOWN, but it never reports it as "RUNNING".
Now, being that there is no mention of this issue on the mainline build thread for the wrx36, its probably a fair guess that its something NSS related. when I reflash the image I built a month or so ago everything works so its not hardware. and the fact that @larrynz also has this issue on his wrx36 NSS build
would seem to indicate it isnt due to my rather extensively customized configuration. Furthermore, the fact that he is seemingly the only other wrx36 owner with this suggests that something beyond just using an NSS build is triggering this issue.
Looking through the commits made in the 1st 2 weeks of May. Out of the ones that apply at all to the WRX36, I only saw 3 or 4 that looked like they might be relevant:
- bumping qca-nss-dp to 12.5.r2 for kernel 6.6
- bumping the kernel to 6.6.30
- some GRO/GSO-related patches
The GRO/GSO-related ones caught my attention since I seem to remember some discussion about GRO/GSO being problematic a couple hundred messages previously in this thread. These patches seemed largely related to ip6, and it occurred to me that if your fix for those GRO/GSO problems was causing stuff to break without ip6 connectivity it would explain why Im having this problem while almost no one else is, why it worked with the same config a month ago, why it is only WAN thats broken while everything else works, and why trying damn near literally everything else I can think of to fix it hasnt worked.
So, @qosmio -- any chance Im on to something here? If not, any ideas for what might be causing this issue? THanks in advance for the help.
