ALTQ on EPAIR interface?

[Mark Martinec]

The ALTQ(4) man page (FreeBSD 9.1-STABLE) claims that
altq is supported on the epair(4) interface, yet when such
interface is specified in the 'altq on' directive in pf.conf,
the pf complains:

# service pf start
Enabling pfpfctl: epair0a: driver does not support altq

So, does it, or does it not support the altq?


Background: the intention is to provide some QoS on
the inner side of a tunnel carrying both IPv4 and IPv6
traffic to a remote site. Apparently the GIF interface
also does not support altq, so the idea was to put epair
in the mix. Applying altq to an outer ethernet interface
does not allow classifying on the inner contents of
the tunnel afict, so it doesn't look line an option.
