Please send the patch directly to the mailing list, not as an attachment.
Otherwise there is no way to review the patch on the mailing list.

`git send-email` should do that for you.

About the commit message:

The section "Notes on the encoding chosen below" is really not needed,
unless something is not a direct translation from text to the standard
rules for wireless-regdb, or if other materials were referenced.

So talking about "Indoor" encoded as "NO-OUTDOOR" is redundant. Mentioning
DFS is also not needed, since it is obvious from the table you provided.
AUTO-BW for 5150-5350 MHz is also quite standard.

Things that are worth mentioning:

1. TPC requirements in the regulation and what was done to make the rule
   compliant (as we don't support TPC)
2. Choice between indoor-only and indoor+outdoor rules when both exist
   but with different requirements (database and Linux support only one
   rule per band)
3. unique 5.8 GHz figure as you gave

Also:

* 5725-5875 MHz uses the higher of the two stated EIRP figures
  (4000 mW for 20 MHz channels) since wireless-regdb expresses a
  per-band ceiling, not a per-channel-width ceiling.

This is slightly wrong. wireless-regdb expresses a ceiling that makes
devices compliant with all regulations in all configurations. So if
there is a power spectral density that allows the maximum EIRP at
a wider channel, but a reduced EIRP at 20 MHz, we will use the reduced
number.

As for 10 MHz, I don't think it is supported, so we don't really consider
that case. I could be wrong though.

Johannes, could you shed some light on 10 MHz channel width support?

Thanks
