Hello, 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=altq#end>* The driver modifications described in altq(9) <https://www.freebsd.org/cgi/man.cgi?query=altq&sektion=9&apropos=0&manpath=FreeBSD+11.0-RELEASE+and+Ports>; are required to use a cer- tain network card with *ALTQ*.

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 += len; 524 if (mflags & (M_BCAST|M_MCAST)) 525 ifp->if_omcasts++; 526 527 if ((ifp->if_drv_flags & IFF_DRV_OACTIVE) == 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.
