Subject: [PATCH] mwl8k: inject DS Params IE into beacons if missing
Some Marvell AP firmware used with mwl8k misbehaves when beacon frames
do not contain a WLAN_EID_DS_PARAMS information element with the current
channel. It was reported on OpenWrt Github issues [0].
When hostapd/mac80211 omits DS Params from the beacon (which is valid on
some bands), the firmware stops transmitting sane frames and RX status
starts reporting bogus channel information. This makes AP mode unusable.
Newer Marvell drivers (mwlwifi [1]) hard-code DS Params IE into AP beacons
for all chips, which suggests this is a firmware requirement rather than
a mwl8k-specific quirk.
Mirror that behaviour in mwl8k: when setting the beacon, check if
WLAN_EID_DS_PARAMS is present, and if not, extend the beacon and inject
a DS Params IE at the beginning of the IE list, using the current
channel from hw->conf.chandef.chan.
Tested on Linksys EA4500 (88W8366).
