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.

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

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.

ieee80211_drop_unencrypted is called from ieee80211_rx_h_mesh_fwding and
ieee80211_frame_allowed.
Since ieee80211_rx_h_mesh_fwding can forward packets for other mesh nodes
and is called earlier, it needs to check the decryptions status and if the
packet is using the control protocol on its own, instead of deferring to
the later call from ieee80211_frame_allowed.
Because of that, ieee80211_drop_unencrypted has a mesh specific check
that skips over the mesh header in order to check the payload protocol.
This code is invalid when called from ieee80211_frame_allowed, since that
happens after the 802.11->802.3 conversion.
Fix this by moving the mesh specific check directly into
ieee80211_rx_h_mesh_fwding.

This can be used to selectively disable feature flags for checksum offload,
scatter/gather or GSO by changing vif->netdev_features.
Removing features from vif->netdev_features does not affect the netdev
features themselves, but instead fixes up skbs in the tx path so that the
offloads are not needed in the driver.
Aside from making it easier to deal with vif type based hardware limitations,
this also makes it possible to optimize performance on hardware without native
GSO support by declaring GSO support in hw->netdev_features and removing it
from vif->netdev_features. This allows mac80211 to handle GSO segmentation
after the sta lookup, but before itxq enqueue, thus reducing the number of
unnecessary sta lookups, as well as some other per-packet processing.
