In P2P GO mode, if the P2P client device is not VHT capable and only HT capable, but the DUT P2P GO is VHT capable and advertises 2x2 NSS and sends packets with 2x2 rates, it results in interop issues with HT only capable P2P client devices. When GO is operating in DBS mode, GO beacons advertise 2x2 capability but include OMN IE to indicate current operating mode of 1x1. But here peer device is only HT capable and will not understand OMN IE. Check if the P2P client device is only HT capable and has "\x00\x50\xf2\x04". Then downgrade the P2P GO operation to 1x1 nss. Modify rx mcs map value in association response to enable only mcs 0-7. Change-Id: I7177c5aee9a560a20c50a63886c0ee77f7d617ae CRs-Fixed: 2464925
