Shayne ChenandFelix Fietkau 63a4edf1cb wifi: mt76: mt7996: add macros for pci decive id 
The chipset name (i.e., brand name) used by the driver may cause confusion
with the PCI device ID when adding support for new chipsets.

| Chipset name | PCI device id  |
|--------------|----------------|
| 7996         | 0x7990, 0x7991 |
| 7992         | 0x7992, 0x799a |
| 7990         | 0x7993, 0x799b |

To prevent confusion, replace the code that directly uses the device ID
with macros. This is a preliminary patch to support mt7990 chipset.

Shayne ChenandFelix Fietkau 87c437fa8b wifi: mt76: mt7996: rework mt7996_rx_get_wcid to support MLO 
The wcid idx and band idx in the TXS are sometimes mismatched since the
FW will select a transmission link according to a private algorithm.
That is, the wcid idx in the TXS would be the one registered by the
driver rather than the actual wcid idx used during transmission.
However, the band idx in the TXS is the band select for transmission.
Therefore, we should get the driver-registered wcid in order
to notify the driver the packet has been acked; otherwise,
the driver will be unable to match the transmitted packet and its TXS.
This is a preliminary patch to enable MLO for MT7996 driver.

In order to update the right link information, call the update
rate_control_rate_update() with the right link_sta, and then
pass that through to the driver's sta_rc_update() method. The
software rate control still doesn't support it, but that'll be
skipped by not having a rate control ref.

Since it now operates on a link sta, rename the driver method.

Jakub KicinskiandFelix Fietkau 0ba7a69f89 wifi: mt76: move napi_enable() from under BH 
mt76 does a lot of:

  local_bh_disable();
  napi_enable(...napi);
  napi_schedule(...napi);
  local_bh_enable();

local_bh_disable() is not a real lock, its most likely taken
because napi_schedule() requires that we invoke softirqs at
some point. napi_enable() needs to take a mutex, so move it
from under the BH protection.

mode.

Michael-CY LeeandFelix Fietkau 8c6cb2f97f wifi: mt76: mt7996: fix beacon command during disabling 
When stopping AP, mac80211 frees beacon template before it calls
driver's stop_ap operation. In other words, on the path of stopping
AP, ieee80211_beacon_get_template() must returns NULL in
mt7996_mcu_add_beacon(). In such case mt7996 immediately returns
-EINVAL without telling FW to disable the beacon.

This commit refactors mt7996_mcu_add_beacon() so that FW can be
correctly informed when disabling AP interface.

The non-AP interfaces would not use conf->vht_ldpc so they never set
STA_CAP_VHT_LDPC even if peer-station support LDPC.
Check conf->vht_ldpc only for AP interface.

Without this patch, station only uses BCC to transmit packet in VHT mode.
