[Bug 1881549] Re: BCM43602 [14e4:43ba] Subsystem [1028:0020]: Upgraded to 20.04 and wifi broke

[Sebastien Bacher]

@François, it's uploaded now, if you have any idea on how to improve the
description for the SRU that would help getting the update accepted
(it's likely the SRU team isn't going to approve it until there is a
good testcase description and I don't understand enough the problem and
which devices it applies to to write one)
