[PATCH v4 04/20] nl80211: Route MLME TX via PD wdev based on source address

[Kavita Kavita]

From: Veerendranath Jakkam <vjakkam at qti.qualcomm.com>

When sending MLME frames, check if the source address matches the active
PD wdev MAC address and if so, route the transmission via the PD BSS
with its associated link reference. This ensures management frames are
sent on the correct wdev when a PD interface is active.
