ACK and pushed (prior to seeing Stefan's message, but as I understand
it, 802.1qbh doesn't use these callbacks at all, and this particular
patch is only *decreasing* the number of added callbacks, so if anything
it should make the situation better :-)
Note that it looks like these callbacks are being registered for any
direct interface with a non-null port profile, not just for 802.1qbg. If
others don't need it (can someone verify that? If so, I'll send the
patch), we should add a qualifying if() (possibly at this same place) to
only register if the portprofile type is 802.1qbh, i.e.
if ((virPortProfile->virtPortType ==
VIR_NETDEV_VPORT_PROFILE_8021QBG) &&
(vmOp == VIR_NETDEV_VPORT_PROFILE_OP_CREATE ||
vmOp == VIR_NETDEV_VPORT_PROFILE_OP_RESTORE)) {
