| |
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.
