X-Git-Tag: v3.5~9
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9560e43d6db295215cebb563d467d30218fa29c1;p=thirdparty%2Fiw.git

iw: allow user to enable vendor synchronization when joining mesh

Currently this option just disables the default neighbor offset
synchronization method. It is useful for testing.
