From: Benjamin Beichler Date: Mon, 22 Jan 2018 17:04:36 +0000 (+0100) Subject: mac80211_hwsim: add nl_err_msg in hwsim_new_radio in netlink case X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=301b04040c3ea2512b8936f419efbbaef2645ccb;p=openwrt%2Fstaging%2Fblogic.git mac80211_hwsim: add nl_err_msg in hwsim_new_radio in netlink case Add a NL_ERR_MSG in case of creating a radio by a netlink message to give clear output to the creating process instead of creating only a debug message in kernel log. The same function is used for the creation while module load, so keep the old message, although it should never be thrown while load, because the module controls all mac addresses.
