[PATCH v3 02/25] P2P: Allow P2P IE to be added into NAN SDFs
Shivani Baranwal
quic_shivbara at quicinc.com
Mon Aug 5 02:33:00 PDT 2024
Extend the NAN Subscribe and Publish methods to allow p2p=1 to be
specified to include P2P attributes in a P2P IE to be added into the NAN
Element Container attribute.
