Hello,
I sent this email also to freebsd-pf list. But I think that the main
problem is belongs to sys/net/if_epair.c.
I'm using FreeBSD 10.3-p17 amd64. epair pseudo device is listed as
supperted deviced at the Man page of altq(4).
>From man page of altq :
*SUPPORTED DEVICES <https://www.freebsd.org/cgi/man.cgi?query=3Daltq#end>*
The driver modifications described in altq(9)
<https://www.freebsd.org/cgi/man.cgi?query=3Daltq&sektion=3D9&apropos=3D0&m=
anpath=3DFreeBSD+11.0-RELEASE+and+Ports>
are required to use a cer-
tain network card with *ALTQ*. They have been applied to the followin=

....
But while trying to use it the system says that it's not suppoerted. I
tried on FreeBSD 11 also. The output is below:
pf.conf :
altq on epair0b hfsc bandwidth 1Mb queue { ftp, ssh, icmp, other }
queue ftp bandwidth 30% priority 0 hfsc (upperlimit 99%)
queue ssh bandwidth 30% priority 2 hfsc (upperlimit 99%)
queue icmp bandwidth 10% priority 2 hfsc (upperlimit 99%)
queue other bandwidth 30% priority 1 hfsc (default upperlimit 99%)
# ifconfig epair0 create
# ifconfig epair0a up
# ifconfig epair0b up
# pfctl -f pf.conf
pfctl: epair0b: driver does not support altq
# sysctl -a | grep ALTQ
options ALTQ_NOPCC
options ALTQ_PRIQ
options ALTQ_CDNR
options ALTQ_HFSC
options ALTQ_RIO
options ALTQ_RED
options ALTQ_CBQ
options ALTQ
I have a look on /usr/src/sys/net/if_epair.c, and found the ALTQ section:
514 #ifdef ALTQ
515 /* Support ALTQ via the clasic if_start() path. */
516 IF_LOCK(&ifp->if_snd);
517 if (ALTQ_IS_ENABLED(&ifp->if_snd)) {
518 ALTQ_ENQUEUE(&ifp->if_snd, m, NULL, error);
519 if (error)
520 ifp->if_snd.ifq_drops++;
521 IF_UNLOCK(&ifp->if_snd);
522 if (!error) {
523 ifp->if_obytes +=3D len;
524 if (mflags & (M_BCAST|M_MCAST))
525 ifp->if_omcasts++;
526
527 if ((ifp->if_drv_flags & IFF_DRV_OACTIVE) =3D=
=3D 0)
528 epair_start_locked(ifp);
529 else
530 (void)epair_add_ifp_for_draining(ifp);
531 }
532 return (error);
533 }
534 IF_UNLOCK(&ifp->if_snd);
535 #endif
I have no idea that why it says that it doesn't support altq altough the
source code contains ALTQ section.
