The patchset is tested on my own DLink DSL 3580L router and generated by
claude from our shared notes, i then reviewed it for sanity and
verified it by navigating from the router with modified b43 driver with
my phone.
The shared notes were: logs and dumps taken from the proprietary binary
driver while running the stock firmware in the router, files from
brcmsmac that had some details for rev 22, GPL released broadcom code
in the GPL dump of the vendor, .rodata pieces from the binary driver and
finally logs and dumps from the live b43 running in the router flashed
with openwrt. Gathering all of this was a week long task, and writing
code was only a small part of it, like in the 5% range.
