>Environment:

	System      : OpenBSD 3.3-current
	Architecture: OpenBSD.i386
	Machine     : i386

>Description:

	On a running system (with an existing 'set loginterface' setting) if
	you adjust to a new/diff interface pfctl will not reset the
	stats that have accumulated for the previous interface.

>How-To-Repeat:

	Set loginterface to an existing interface, create some traffic
	and observe the counters change.

	Change the loginterface setting and reload the options from the
	file. Observe that the stats remain from the previous interface.

>Fix:

	(yes, I know about pfctl -F i , but it would be nice to see
	it auto-detect and reset the stats).

	1)
	Perhaps DIOCSETSTATUSIF should detect if the desired interface
	changed and make a call to DIOCCLRSTATUS ?

	2)
	Or to keep it out of the kernel , pfctl can detect the
	desired change in interface monitoring and do a DIOCCLRSTATUS
	after the DIOCSETSTATUSIF ?
