Hi,

It's quite possibly a bug. Please file a PR.

The values should all be stored internally in net80211 in 1/2 dBm
increments. I think the ioctl API should also store all values in 1/2
dBm increments.

I'd check two things:

* that the net80211 maxtxpow values are always correct, assuming 1/2
dBm increments;
* then I'd check ifconfig to ensure maxtxpow is always being printed correctly.



Adrian
