trill.c:

General: should handle the case where native frames
sent to TRILL for forwarding do not have L3 and above
checksums computed when hardware checksum offload feature
is in use. Since they are encapsulated and sent out as 
TRILL packets the hardware cannot compute them and such
pkts are dropped by receiver.

General: Support Bridge instances <-> TRILL instances
Pass bridge instance as TRILL parameter.
Safe to assume Bridge instances are running
before IS-IS is up.

DONE

General: VALID NICK check should handle reserved nick space

General: trill nick structure assume trill socket is
always available, should track trill sockets and when socket
close occurs and the nick structures should be corrected.

311: trill_recv_local should de-capsulate packet
     and forward pkt to local link if it is the
     forwarder on the link.

331: Shouldn't send to bridging as a received frame
     but as a transmit frame.

331: Should clear mblk checksum flags after decapsulation.

361: trill_dest_fwd should check if it is the forwarder
     on the link before forwarding the packet via TRILL.

406-415: should use the RBridge address as dest.

bridge.c

730: fwd_update_local: should we set BFF_LOCALADDR here?

1225: bridge_forward shouldn't forward the frames received
      from TRILL back again.

1363: should check for BFF_LOCALADDR matches before forwarding
      via TRILL

1519: should check if we need to forward via TRILL here

1599: TRILL de-capsulated frames shouldn't be received here, they
      will be treated by bridging as packets received off the wire.
      They should be treated as forward packets and bridge_xmit path
      should be used instead to do source address learning and deliver
      locally and/or to other links.

2040: should use MAXLINKNAMELEN and not MAXNAMELEN here
