Subject: staging: vt6656: Remove dead code hostap.
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a30d534bdab1bec46cca2a58bafdbadd7a64f081;p=openwrt%2Fstaging%2Fblogic.git

staging: vt6656: Remove dead code hostap.

It is based on viawget, proprietary version of wpa supplicant.

The code is not compatible with the current version of hostapd.

It may be possible to implement when the driver is fully converted
to mac80211.
