X-Git-Tag: hostap_2_6~1335
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1d6955e668a4f58af79727a0d774d6819c51d8c5;p=thirdparty%2Fhostap.git

nl80211: Fix SIGNAL_POLL in IBSS and mesh

NL80211_CMD_GET_STATION does not work with the IBSS/mesh BSSID, so clear
the signal strength instead of returning failure when SIGNAL_POLL is
used in an IBSS/mesh.
