Subject: [PATCH 4/5] ieee802154: add support for channel pages from IEEE 802.15.4-2006
IEEE 802.15.4-2006 adds new concept: channel pages, which can contain several
channels. Add support for channel pages in the API and in the fakehard driver.
Signed-off-by: Dmitry Eremin-Solenikov <dbaryshkov@...il.com>
