to serve such events pseudorecursively, when link state
change of interface causes subsequent change on other
interfaces.

clock time to uptime because wall clock time may go backwards.
This is a change in the API which will impact SNMP agents who are using
ifi_epoch to set RFC2233's ifCounterDiscontinuityTime. None are know to
exist today. This will not impact applications that are using the
<index, epoch> tuple to verify interface uniqueness except that it
eliminates a race which could lead to a false assumption of uniqueness.
Because this is a behavior change, bump __FreeBSD_version.

Obtained from: OpenBSD (mickey, mcbride)
a packet has VLAN mbuf tag attached. This is faster to check than
m_tag_locate(), and allows us to use the tags in non-vlan(4) VLAN
producers.
The first argument to VLAN_OUTPUT_TAG() is now unused but retained
for backward compatibility.
While here, embellish a fix in rev. 1.174 of if_ethersubr.c -- it
now checks for packets with VLAN (mbuf) tags, and it should now
be possible to bridge(4) on vlan(4)'s whose parent interfaces
support VLAN decapsulation in hardware.

driver did VLAN decapsulation in hardware, we were passing a frame
as if it came for the parent (non-VLAN) interface. Stop this from
happening.

- ip_fw_chk() returns action as function return value. Field retval is
removed from args structure. Action is not flag any more. It is one
of integer constants.
- Any action-specific cookies are returned either in new "cookie" field
in args structure (dummynet, future netgraph glue), or in mbuf tag
attached to packet (divert, tee, some future action).
o Convert parsing of return value from ip_fw_chk() in ipfw_check_{in,out}()
to a switch structure, so that the functions are more readable, and a future
actions can be added with less modifications.
