Update of /a/cvsroot/src/sys/net
In directory pain.lcs.mit.edu:/a/tmp/cvs-serv15076

Modified Files:
	if_strip.c 
Log Message:
* Put in fix to in bytestuffing/RLL code from Stuart Cheshire, that
  somehow got lost between NetBSD and Linux.    Output side mbuf-walking
  code now correctly bytestuffs mbuf chains, as well as single mbufs
  and clusters.

* Update radio error-parsing code to Stuart's latest stable code.
  We now parse error messages the older code didn't.

* Note where radio-crash watchdogs should be added (the linux code
  is there, #ifdef'ed out). This still just  doesn't work.
  The radio reset doesn't always work even when slattatch is first started,
  but I have a radio with old firmware, which may be a contributing factor.

* Correct the checks for the tty output queue being overfull;  estimate
  the stuffed pkt size as  (original * 65/64) + STRIP_HDRLEN + 2,
  instead of SLIP's (2*SLMTU).  Re-enable the disabled  check now the
  size estimate isn't excessively large.

* Fix BPF tapping of strip interfaces,  STRIP packets are wrapped
  in a SLIP bpf  header.   This implies no BPF support for arp or atalk,
  even though Linux boxes are sending arp requests and  gratuitous arps.
  There may be no good  fix short  of adding explicit  STRIP encapsulation
  support to bpf/tcpdump.

* Still need a solid walkthrough, and  rewrite to eliminate redundant
  receive-side mbuf copying.
