Hi Dan,
   Thanks for the review. Sorry I could not reply earlier since I was on 
vacation. Please find comments inline.

Thanks

Would you like me to add a sub section regarding 802.1X?

OK. Will this text work?

"A host connected to a bridge port does not receive any explicit 
indication that the bridge has started forwarding packets."

Will replace with

"Where a host receives the Systems Capabilities TLV which
  indicate that no Bridging is occurring on the LLDP
  transmitter, then no delays for STP calculation will be applied to
  packets sent through this transmitter."

Is that OK?

OK. Will do.
