From: Tomas Winkler Date: Mon, 5 May 2008 02:22:34 +0000 (+0800) Subject: iwlwifi: generalize iwl4965_send_add_station function X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=133636deffc86809f59a0c8b768408d13237a9a2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git iwlwifi: generalize iwl4965_send_add_station function This patch moves iwl4965_send_add_station to iwlcore under new name iwl_send_add_sta. Function uses build command handler in order to support multiple HWs. Signed-off-by: Tomas Winkler Signed-off-by: John W.
