This patchset adds new channel types -- 5MHz and 10MHz. Channels
with such bandwidth are used in IEEE 802.11p with frequencies
ranging from 5850 to 5925 MHz. Since OCB mode defined in 802.11p
does not use beacons, the channel frequencies including the
bandwidth should be set by all STAs before joining the network.
This patchset adds the possibility of setting the channel
bandwidth via netlink (i.e. from userspace).
Potential issues:
CRDA reports to the kernel the information about the maximum
channel bandwidth allowed for some particular range of channels/
frequencies. In case the maximum BW is usual 20 or 40 MHz, e.g.
(2400 - 2483.5 @ 40), it is possible to configure a channel with
5MHz or 10MHz in that range. Is this behavior acceptable or
should it be prevented?
