On the STA side:

The RSN IE in the EAPOL-Key and the 3/4msg are the same, and contain
only the CCMP pairwise suite.  The RSN IE in the Beacon/ProbeResp debug
message contains both CCMP and TKIP pairwise suites.

Earlier in the run we have:

1417557228.979261: WPA: set AP RSN IE - hexdump(len=26): 30 18 01 00
00 0f ac 04 02 00 00 0f ac 04 00 0f ac 02 01 00 00 0f ac 02 00 00
1417557228.979342: WPA: Set own WPA IE default - hexdump(len=22): 30
14 01 00 00 0f ac 04 01 00 00 0f ac 04 01 00 00 0f ac 02 00 00

which is where the extra TKIP bit comes from.  I'm guessing this is from
wpa_supplicant_set_suites() because of the closely paired AP RSN IE/own
WPA IE calls.

Brent, is there any chance you can run the supplicant on the laptop with
"-dddt" to get *all* the debug messages?  It seems the logs are missing
quite a few that could tell us where wpa_supplicant_set_suites() is
getting called.
