Subject: [PATCH 2/2] mwl8k: setting IEEE80211_HW_CRYPTO_ENABLED for AP mode
Date: Fri, 15 Apr 2011 10:24:38 +0530	[thread overview]
Message-ID: <20110415045430.GA11530@hertz.marvell.com> (raw)

For AP mode, driver sets IEEE80211_HW_CRYPTO_ENABLED hardware flag to avoid
mac80211 reserving tail room space for crypto suite.
