wifi: cfg80211: Add MAC address filter to remain_on_channel
Currently the remain_on_channel operation does not support
filtering incoming frames by destination MAC address. This
prevents use cases such as PASN authentication in the
responder side that need to receive frames addressed to a
specific MAC during the off-channel period.
Add an rx_addr parameter to the remain_on_channel operation
callback and propagate it through the call chain from nl80211
to driver implementations. Introduce the extended feature
NL80211_EXT_FEATURE_ROC_ADDR_FILTER as a capability gate so
that cfg80211 rejects the request if the driver does not
advertise support for address filtering. Extract the address
from the NL80211_ATTR_MAC attribute when provided in the
netlink message and update the tracing infrastructure to
include the address in remain_on_channel trace events. The
rx_addr parameter is optional and can be NULL, maintaining
backward compatibility with existing drivers.
