I've gotten kernel patches (and some other GPL bits and bobs, although with time they got rid of everything other than the kernel) on request for ROS6.
For ROS7, however, support said in June:
That is not yet readily available since v7 is not really complete yet and is during heavy development right now, everything is changing, including the kernel. I will inquire how long it will take to get the files you need and will let you know once I have some information.
This is a good reminder to ping them again about this.
Do you happen to know, if the RB2011 will be stuck on the (dead-end) ar71xx release, or whether somebody is working on porting it to the newer ath79 platform with LTS?
This is the first I've heard of this. I didn't know it could map to a new platform.
I have two and just got them working and haven't updated in maybe a year. I use them as internal switches and only really use vlans + dhcp.
It might be interesting to see if porting is a big deal. I have one annoying weirdness where ports are labeled sfp,1-5,6-10, but the logical mapping is really screwed up switch0:6, switch0:1,2,3,4,5, then switch1:5,4,3,2,1 (reversed)
