Subject: Configure new GTK/IGTK to driver in case of TKIP countermeasures
X-Git-Tag: hostap-1-bp~1
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9354e59480fbdffa4e773728909d1e0d4a2be68a;p=thirdparty%2Fhostap.git

Configure new GTK/IGTK to driver in case of TKIP countermeasures

The GTK is renewed in the hostapd after a MIC attack dissassociation
without informing the driver, causing decryption failures. This patch
sends the new GTK/IGTK to the driver after it is updated by the hostapd.
