Perhaps you would consider including it? My patch below. The only change I made to the OpenWRT version was to reflect the move of drv->ioctl_sock to drv->global->ioctl_sock and to refresh the line numbers.

This is already accounted for by the upstream Makefile, however wrongly depending on !CONFIG_DRIVER_BSD, while it is actually depending on the target libc rather than the kernel (Closes: #737465). Thanks to Cyril Brulebois <[email protected]> and Steven Chamberlain <[email protected]>. * import "hostapd: Fix WDS VLAN bridge handling" by Felix Fietkau <[email protected]> from upstream, thanks to Mark Hindley <[email protected]> (Closes: #737109). * drop build-conflicts with libqt3-dev as the package is no longer available >= lenny, thanks to Michael Biebl <[email protected]>. * drop pre-dependency on dpkg (>= 1.15.6~), data.tar.xz-member-without-dpkg- pre-depends is no longer a problem after Ubuntu lucid is EOL. Thanks to Michael Biebl for noticing. * drop build-dependency on libdbus-glib-1-dev, it is no longer required for dbus-binding-tool, thanks to Michael Biebl. * allow parallel building. * fix spelling s/algorith/algorithm/. * add lintian overrides for false positive spelling complaints.
