The firmware can have the capability to manage the channel context scheduling on multiple roles running on the device including Station, AP and P2P GC/GO mode (will be extended based on the future patchset) to help users sharing the network with others on a single device. The firmware is able to support the channel chanctx up to 2 interface simultaneously running on the different channels. Another thing to be noted is that before the driver is going sent out the management frames, the driver has to get the privilege from the firmware to occupy the current channel context until the frame handshake is completed and then get the privilege back to the firmware.

Introduce remain_on_channel support. Additionally, we add mt7921_check_offload_capability to disable .remain_on_channel and .cancel_remain_on_channel and related configuration because those operations would rely on the fundamental MCU commands that will be only supported with newer firmware.

mt7915 does not have a per-band number of chains unlike the other chips, it only has a total number of chains. Yet the current code would consider the total number as a per-band number. For example, it would report that a 2x2 + 2x2 DBDC card have 4 chains on each band and set chainmask to 0b1111 for the first interface and 0b11110000 for the second.

The MIB INFO command is fetching MIB_BUSY_TIME, MIB_TX_TIME, MIB_RX_TIME and MIB_OBSS_AIRTIME from the radio and filling out cc_busy, cc_tx, cc_bss_rx and cc_rx respectively. busy should be >= tx + rx >= tx + bss_rx but we don’t always quite see this. Sometimes tx + rx is a bit higher than busy due to inaccurate accounting, so this patch recalculates numbers to make them more reasonable. Reported-By:

In previous, we only allow user to configure tx antenna mask contiguously (e.g. 0x3, 0xf). This patch allows user to configure tx antenna mask interleavingly (e.g. 0x5, 0x8). By setting proper antenna mask and nss, user can prioritized the signal of different antennas, which helps to test their performance in normal mode. Signed-off-by:

A variant of mt7916 supports up to 3 tx/rx paths but with only 2 spatial streams. An example usage of the 3rd path is to server as an auxiliary for beamforming. In order to deal with this case, this patch reworks some parts to correctly use paths or streams. Signed-off-by:
