Description fujiwara 2000-12-07 19:50:01 UTC 
	FreeBSD's bpf doesnot distingish PPP and CISCO_HDLC.
	tcpdump on CISCO_HDLC link with some expressions,
	tcpdump don't catch any bpf data.

Fix: Support DLT_CHDLC with BPF and sr driver,
	or catch CISCO_HDLC packet when DLT_PPP.
How-To-Repeat: 
	use RISCom sr driver with CISCO_HDLC mode.

I'm trying to deal with tcpdump stuff.
Comment 2 Bill Fenner 2001-11-03 00:57:21 UTC 
Could you try this patch?  BPF knows about Cisco encapsulation; it just
needs to be told that the interface
is using it.

Thanks,
  Bill
