Subject: [PATCH 4/6] iwlwifi: rename rxq->dma_addr
Date: Mon, 14 Jun 2010 11:24:50 -0700 [thread overview]
Message-ID: <1276539892-12471-5-git-send-email-reinette.chatre@intel.com> (raw)
In-Reply-To: <1276539892-12471-1-git-send-email-reinette.chatre@intel.com>
From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
Rename rxq->dma_addr to rxq->bd_dma to better emphasize that the
physical address stands for the receive buffer descriptor's address.
