Config Methods in WSC IE on P2P GO
Tue Sep 11 05:51:13 PDT 2012
Currently the GO sends Probe Response frame which contains WSC IE with Config
Methods. The Config Methods includes 0x2108 for instance.
 says "Configuration Methods corresponds to the methods the AP supports as
an Enrollee for adding external Registrars." at 8.2.5 Probe Response
(D-AP/Registrar) Table 7 . Attributes in WSC IE in the Probe Response frame.
 says "P2P Group Owner role:Provides WSC Internal Registrar functionality."
in 2.1 P2P components. And  says "P2P Group Owner shall not cross connect
between the WLAN and P2P Group using layer 2 mechanisms." in 3.2.6
Communication in a P2P Group.
So I think these imply "GO could not use external registrar". So I think the
Config Methods could be zero.
But I know there are confused devices such as using Config Methods in WSC IE
even if it is a P2P Client. So even if my consideration is acceptable, the code
should be enclosed by CONFIG_P2P_STRICT macro.
