Okay ... try this. Not final yet, but should be functional. With this
you should be able to:
1) Safely remove an interface with active queues
2) Re-add the interface and *magically* get the queues back
3) Write queue rules for non-existing interfaces
- Note that we will assume an MTU of 1500 and you have to specify a
fixed bandwidth as we don't know the interface's native speed
- Obviously these queues will be activated as soon as a matching
interface is created.
BUGS: Doesn't print queues on removed interfaces at all. Should be
changed to something like "queue foo on bar0 (N/A) ...", but it seems I
was too strict with the local_flags. The error handling might need some
work in order to avoid panic if something goes wrong while we de-activate
queues.
I'd like to hear back from you in order to see if I at least got the basic
workings right enough so you can survive the mpd interface destroy.
Ok, it survives 20 consecutive restarts now without problems. I didn't
test more as i'm not 100% sure what my provider will do otherwise...
N.B. This is 8-CURRENT but it had the same problem as the 7-STABLE box.
Could you - in addition to you current setup w/ if-up script - also test
the magic part? i.e. load the ruleset before loading mpd. This should
now be possible as long as you don't put "set loginterface" or fixed
interface-to-address src/dst in it \o/
Yes, the *magic* seems to work (without up-script):

Stopping mpd4.

Max, thanks a lot! Keep up the great work you are doing on pf4freebsd.
Cheers
