Also, you can certainly remove the 'ret' variable. johannes -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Adding this opcode, allows the TI wireless driver, to report throughput directly from FW to mac80211. This is used mainly for mesh metric calculation. Signed-off-by: Maxim Altshul <maxim.altshul@ti.com> --- Changed the units of returned value. drv_get_expected_throughput returns units of Kbps by definition, and thus we must comply as well. Mbps * 1000 = Kbps. drivers/net/wireless/ti/wlcore/main.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+)
