[Linux-HA] Two questions about the heartbeat packages

[mingdao lu]

I have very special application case based on Heartbeat 2 framwork. In the
application, it grasp all packages received on the ethernet port, including
the heartbeat UDP and ARP broadcast packages. So the Heartbeat functions can
not receive any packages from kernel automatically.
I have 2 questions about this senario.

1, Besides UDP and ARP broadcast, what else TCP/IP protocols are used in
Heartbeat 2 function.

2, Where is the entrance for heartbeat to handle UDP and ARP broadcast
packages? I intend to send these grasped UDP and ARP packages to Heartbeat
process manually. So I need to know how heartbeat handles these packages.

Thanks a lot :)
