Jakub Kicinski 1877461224 wl3501_cs: use eth_hw_addr_set()

of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all

Use dev_addr_set() to match the existing logic.
setup_card() is always passed netdev->dev_addr, so pass the netdev
pointer instead and assign the address using a helper there.

Jonas Dreßler 5943a864fe mwifiex: Deactive host sleep using HSCFG after it was activated manually
When powersaving (so either wifi powersaving or deep sleep, depending on
which state the firmware is in) is disabled, the way the firmware goes
into host sleep is different: Usually the firmware implicitely enters
host sleep on the next SLEEP event we get when we configured host sleep
via HSCFG before. When powersaving is disabled though, there are no
SLEEP events, the way we enter host sleep in that case is different: The
firmware will send us a HS_ACT_REQ event and after that we "manually"
make the firmware enter host sleep by sending it another HSCFG command
with the action HS_ACTIVATE.

Now waking up from host sleep appears to be different depending on
whether powersaving is enabled again: When powersaving is enabled, the
firmware implicitely leaves host sleep as soon as it wakes up and sends
us an AWAKE event. When powersaving is disabled though, it apparently
doesn't implicitely leave host sleep, but instead we need to send it a
HSCFG command with the HS_CONFIGURE action and the HS_CFG_CANCEL
condition. We didn't do that so far, which is why waking up from host
sleep was broken when powersaving is disabled.

So add some additional state to mwifiex_adapter where we keep track of
whether host sleep was activated manually via HS_ACTIVATE, and if that
was the case, deactivate it manually again via HS_CFG_CANCEL.

Jonas Dreßler cc8a8bc374 mwifiex: Send DELBA requests according to spec
While looking at on-air packets using Wireshark, I noticed we're never
setting the initiator bit when sending DELBA requests to the AP: While
we set the bit on our del_ba_param_set bitmask, we forget to actually
copy that bitmask over to the command struct, which means we never
actually set the initiator bit.

Fix that and copy the bitmask over to the host_cmd_ds_11n_delba command
struct.

Shayne Chen bbf77f6cce mt76: mt7915: enable HE UL MU-MIMO
Enable HE UL MU-MIMO in sta_rec_muru, which works on both ap and station
mode.

For sending trigger frames, one of the conditions fw uses is to check if
mib rx airtime meets the threshold.
There's a main control of mib rx airtime report register in fw, so we
need to enable the register by mcu cmd instead of directly writing it,
otherwise it will still be disabled by fw.
