batman-adv: ELP - use wifi tx bitrate as fallback throughput (2b1aa5a4) · Commits · 戴 / test

Some wifi drivers (e.g. ath10k) provide per-station rx/tx values but no estimated throughput. Setting a better estimate than the default 1 MBit makes these devices work well with B.A.T.M.A.N. V. Signed-off-by:
