Subject: [PATCH wpan-next v3 0/4] ieee802154: Improve durations handling

These patches try to enhance the support of the various delays by adding
into the core the necessary logic to derive the actual symbol duration
(and then the lifs/sifs durations) depending on the protocol used. The
symbol duration type is also updated to fit smaller numbers.

Having the symbol durations properly set is a mandatory step in order to
use the scanning feature that will soon be introduced.

Changes since v2:
* Added the ca8210 driver fix.
* Fully dropped my rework of the way channels are advertised by device
  drivers. Adapted instead the main existing helper to derive durations
  based on the page/channel couple.

Miquel Raynal (4):
  net: ieee802154: ca8210: Fix lifs/sifs periods
  net: mac802154: Convert the symbol duration into nanoseconds
  net: mac802154: Set durations automatically
  net: ieee802154: Drop duration settings when the core does it already
