[PATCH] S1G: Add support for freq_khz

Hi,
I’ve rebased your patch on top of latest master and went over some
of the whitespace changes. I also incorporated the very small changes made
by JUN-KYU SHIN in "[PATCH v2, 2/2] Add hw mode config for 80211ah”
which makes it a bit more complete. (But it’s definitely not yet fully complete.)
After this patch I hope that I can get hostap working with Newracom’s
NRC7292 (without the driver faking other standards/channels like it does now)
and that might result in future patches to improve 802.11ah AP(/STA) support.
Side-note, I’m not too familiar with git-email, so apologies for any mistakes.
---
This commit adds support for specifying a channel frequency in kHz
and a 802.11ah (S1G) mode
The predominate use case is S1G. Many S1G channels are centered on
frequencies which a MHz value does not support. Additional freq_khz
parameters have been added as required to the key structures that
maintain the operating parameters of a hostapd AP. These freq_khz
params have been added to key functions alongside the traditional freq
parameter as an alternative.
The extent of this commit is the support of core BSS functionality using
freq_khz. It is intended that several follow up commits will make use of
this concept to support more advanced features.
Because this commit has introduced an alternative parameter that is used
instead of the traditional freq param we needed to introduce logic that
would support this change. We opted for logic that checks if freq_khz is
set, and if so, uses that parameter going forward, otherwise if freq_khz
is not set, freq is used as per the existing use case.
This approach prevents regression for existing code.
The kernel maintains frequencies by using a combination of freq and
freq_offset parameters. This patch includes a number of changes to support
this concept.
