I'm wanting to build a new 21.02 firmware image for my Linksys WRT1900ACSv2 wireless router. I would like to clarify if I can skip the following packages from being included in the final firmware image as I believe DSA is part of the kernel and the old packages are no longer needed:
kmod-swconfig
swconfig
As a side note, how do I find out if a device supports DSA? Is there a list of devices that fully support DSA on the OpenWrt Wiki? It'll be handy to know when looking for second hand wireless routers as I try to recommend OpenWrt to friends and family, and I often use pre-owned wireless routers in which I compile the firmware for them with the settings baked in.
I did come across this link below but it has been updated since March.
Maybe I’m missing something super-obvious, but when 21.02 was released I flashed my Linksys WRT1900ACS with a standard OpenWRT factory image (not sysupgrade) and DSA worked fine OOB (getting WAN, LANx interfaces).
My WRT1900ACSv2 is still on v19.07.4. I haven't tried the v21.02 yet as I will need some time to test setting up the VLANs with the UCI commands as I make good use of UCI-default scripts to configure the entire router from a default state.
