From d5b25c904755676d2de00cfcc24515ef554cb2bf Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Mon, 7 Jun 2010 13:21:46 -0700 Subject: [PATCH] iwlwifi: rename rxq->dma_addr Rename rxq->dma_addr to rxq->bd_dma to better emphasize that the physical address stands for the receive buffer descriptor's address.
