/**
|
|
ATBridge is a limited function AppleTalk bridge that allows GSPort to connect to an
|
|
EtherTalk network. The bridge has two ports, one the emulated LocalTalk port and the
|
|
other an EtherTalk Phase II port.
|
|
|
|
Due to timing requirements of LocalTalk, it is not reasonable to transparently bridge
|
|
LLAP traffic to ELAP. For example, implementing the lapENQ/lapACK LLAP control packets
|
|
requires AARP queries on the ELAP port, which can't be reasonably done within the 200us
|
|
LLAP interframe gap. So, we must implement the local bridge functionality detailed
|
|
in "Inside AppleTalk", including AARP, RTMP, ZIP, and DDP routing.
