Subject: [PATCH wpan-next v2 2/2] net: ieee802154: Move the address structure earlier and provide a kdoc

From: David Girault <david.girault@...vo.com>

Move the address structure earlier in the cfg802154.h header in order to
use it in subsequent additions. Give this structure a header to better
explain its content.
