Subject: Android: Implement SETBAND for scan requests
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=acb97b360033dba1cb26b17aeb8d204fca254b05;p=thirdparty%2Fhostap.git

Android: Implement SETBAND for scan requests

This provides partial SETBAND driver command implementation by
converting the request into a filter for which channels are scanned
by wpa_supplicant.
