non-zero it_interval values have no sense if it_value == 0 but
checked by itimerfix which may cause EINVAL return

6bb904da80 Add a spin lock that prevents the sequencer from attempting to add an 
entry to the QOUTFIFO when it is full.  This should eliminate the
"Timed out while idle" problems that many have reported.

In truth, this is somewhat of a hack.  Although are interrupt latency is
low enough that we should be able to always service the queue in time,
since each entry must be passed up to the higher SCSI layer for what can
be a large amount of processing (perhaps even resulting in a new command
being queued) with interrupts disabled, we need this mechanism to avoid
overflow.  In the future, these additional tasks will be offloaded to a
software interrupt handler which should make this hack unnecessary.

d0850efd52 Fixed vnode corruption by undefined case in union_lookup(). When 
uerror == 0 && lerror == EACCES, lowervp == NULLVP and union_allocvp
doesn't find existing union node and new union node is created.

Sicne it is dificult to cover all the case, union_lookup always
returns when union_lookup1() returns EACCES.

a2d21c0047 Fix a traceroute problem in the CISCO HDLC mode. (cisco routers not 
returning ICMP_TIMXCEED)

use CISCO_UNICAST instead of CISCO_MULTICAST to send normal packets.
this is needed for packets to get processed by a cisco router,
but doesn't matter if a packet is just forwarded.

running with, but the remainder (PAP & CHAP) ain't ready for prime-
