The trace is obtained using the P2P implementation in wpa_supplicant when the P2P Client is trying to obtain the network credentials from the P2P GO. The chipset being used is AR5412 with ath5k. These are the steps that look strange to me in the trace:

It would be much easier to figure out what is going on based on a debug
log from wpa_supplicant. Sniffer trace like this (especially with all
the details removed) does not really provide any good explanation for
the issues you mention.
