Subject: [patch] iwlwifi: range checking issue
Date: Sun, 28 Mar 2010 11:55:00 +0000	[thread overview]
Message-ID: <20100328115500.GX5069@bicker> (raw)

IWL_RATE_COUNT is 13 and IWL_RATE_COUNT_LEGACY is 12.

IWL_RATE_COUNT_LEGACY is the right one here because iwl3945_rates
doesn't support 60M and also that's how "rates" is defined in
iwlcore_init_geos() from drivers/net/wireless/iwlwifi/iwl-core.c.

        rates = kzalloc((sizeof(struct ieee80211_rate) * IWL_RATE_COUNT_LEGACY),
                        GFP_KERNEL);
