The problem here is that some devices (notably iwlwifi) will not allow

So I prevented it generally, but we can make it device dependent. I
don't like it much, but I suppose we can do it. Try this patch:
http://p.sipsolutions.net/0129f39c7d882289.txt
It will still prohibit this configuration when the driver said it's not
allowed, but will allow it when there were other reasons to not allow
it.
Just to report, with the patch under discussion re-applied
(3a40414f826a8f1096d9b94c4a53ef91b25ba28d), plus the patch at your link
above, my throughput is back to normal again.
Ok, thanks.
So I guess the above patch resolves the issue (on the face of it) for
me, but whether it is a suitable solution I've no idea.
Right, we're still looking at that. It seems that it's not an ideal
solution, the regulatory change I proposed is probably better. Could you
check if it helps as well? That is, remove this patch, and apply this
one: http://p.sipsolutions.net/8877cbe3440d94b1.txt
OK, so I've removed 0129f39c7d882289.txt, applied 8877cbe3440d94b1.txt,
and I've kept 3a40414f826a8f1096d9b94c4a53ef91b25ba28d applied.
Rebooted, and happy to report throughput is still good, so
8877cbe3440d94b1.txt also "fixes" it for me.
