OK. Thanks Christopher. Regarding a potential backport, it certainly does not come from an updated firmware : the firmware files /lib/firmware/brcm/bcm43xx-0.fw and /lib/firmware/brcm/bcm43xx_hdr-0.fw are the same when used with both kernels on my machine.
So it comes from an update in the driver itself.
