  2. Add RawHardwareAddress, use it in wire ndisc. 

    This avoids wire needing to know what medium we're on.

  6. ieee80154: process packets without the FCS. 

    We assume the FCS is checked by lower layers or by hardware.

- Makes it consistent with Ethernet mediums, where we don't handle the FCS either.
- Linux ieee802154 raw sockets send/receive packets without the FCS.

  8. example/6lowpan: expand readme, do not use monitor interface. 

    Using a raw socket on `monitor0` causes weird results: packets we receive
include FCS, packets we send are parsed as if they didn't have FCS, except
by wireshark which always expects a FCS??

Turns out the sane way is to use raw sockets on normal `wpanX` interfaces,
in which case all packets we send/receive are without FCS.

  9. Use one PAN ID for source and destination 

    Also check for the correct destination PAN id when receiving a frame (as
discussed). Linux does this as well.
However, hardware implementations also can drop those packets.

    When there is no medium in the feature flags, then there is no
HardwareAddress.
