mac80211: ath9k: Increase allowed antenna gain to 6 dBi
FCC allows maximum antenna gain of 6 dBi. 15.247(b)(4): > (4) The conducted output power limit > specified in paragraph (b) of this section > is based on the use of antennas > with directional gains that do not exceed > 6 dBi. Except as shown in paragraph > (c) of this section, if transmitting > antennas of directional gain greater > than 6 dBi are used, the conducted > output power from the intentional radiator > shall be reduced below the stated > values in paragraphs (b)(1), (b)(2), > and (b)(3) of this section, as appropriate, > by the amount in dB that the > directional gain of the antenna exceeds > 6 dBi.

Subject: [PATCH] ath9k: adjust tx power reduction for US regulatory
domain
-FCC regulatory rules allow for up to 3 dBi antenna gain. Account for
+FCC regulatory rules allow for up to 6 dBi antenna gain. Account for
this in the EEPROM based tx power reduction code.
