The quote was: > I would prefer if this was *dBm*, rather than mBm, and be allowed to > take float values, i.e. this would become "limit 20". I read that as "iw should convert fractional dBm to mBm" not "kernel should only support dBm". ath10k might only support dBm, fine -- but even ath5k could support per-packet transmit power in 0.5 dB steps, so this is already limiting applicability to existing hardware. -- Bob Copeland %% https://bobcopeland.com/ _______________________________________________ ath10k mailing list ath10k@lists.infradead.org http://lists.infradead.org/mailman/listinfo/ath10k
