wifi: cfg80211: add attribute for TX/RX denoting there is no station
For MLD stations, userspace may need to explicitly transmit a frame to
a specific link address. In that case, it needs to ensure that no
address translation happens.
In the reverse case of an RX, userspace may need to know the link
address for a frame. By passing the information whether a STA is known
for the frame, userspace knows whether link translation happened and
can do the reverse lookup when needed.
This is important for flows where a STA is still registered but the
connection has been lost and it is returning again.
