    ieee802154: hwsim: add replacement for fakelb · f25da51f
    Alexander Aring authored
    This patch adds a new virtual driver mac802154_hwsim which is based on
    the fakelb driver.
    The fakelb driver will get deprecated and hopefully removed someday.
    The main reason for doing this step is to rename the driver to
    mac802154_hwsim to have a similar naming scheme as mac80211_hwsim,
    which is more popular in the 802.11 wireless word and the idea is the
    same behind this driver.
    
    The new features of this driver are to have knowledge about connected
    edges, which can be changed during runtime. This offers a testing
    environment for routing protocols e.g. RPL.
    The default behaviour is still as fakelb: two radios connected to each
    other. New added radios during runtime will not be connected to other
    wpan_hwsim instances.
    
    The netlink api is not namespace aware on purpose, only the registered
    wpan_phy's can be moved to namespaces. The physical layer according to
    wiresless "air" communication can be handled across namespaces.
    
    Furthermore the edges can be weighted with the LQI value according IEEE
    802.15.4 which offers additional handling to mark bad or good connection
    indicators to other connected virtual phys.
