share/man/man4 : ifmedia.4
Log message:
Expand the 802.11 section in the ifmedia(4) man page.
It has become increasingly difficult to make sense of wireless man pages
without resorting to Wikipedia for help. My goal is to provide background
information about technical terms used across wireless man pages, such as
"MIMO" and "MCS". jmc@ suggested that ifmedia(4) would be a suitable place.
This new ifmedia(4) section provides context and equips curious readers
with additional technical terms to research if they wish.
Information about how 802.11 transmission rates work (roughly) and how they
evolved with each standard revision we support has been added.
Obsolete information about 2GHz restrictions in France has been removed.
Information about 5GHz channels has been added.
High-level information (11a/b/g/n/ac mode, hostap/ibss/monitor mode,
information about channels) is discussed before going into detailed
discussion about 802.11 data rates.
