From ed6a3803408f18da387463d569b4edc5078fd9aa Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Mon, 2 Jan 2012 16:10:08 +0200 Subject: [PATCH] iwlwifi: add fw_alive to transport layer API, kill tx_start Define a new handler in the transport layer API: fw_alive. Move iwl_reset_ict to this new handler, and move the content of tx_start to this handler.
