Subject: NAN: Check SYNC_CONFIG support
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d7f20d42817a3ea9f2eaf6be12c8fe0be1c04586;p=thirdparty%2Fhostap.git

NAN: Check SYNC_CONFIG support

Currently, NAN support is assumed if NAN device interface is supported.
Since wpa_supplicant NAN implementation is intended to work with new
drivers and kernel only, make sure
WPA_DRIVER_FLAGS_NAN_SUPPORT_SYNC_CONFIG flag is set.
