Bandwidth limiting via pf or ipfw ?
ipfw may be more forward to use since its usually easier to comprehend the
syntax and type it directly on the command line.

ipfw (pf too?) can artifically control speeds via dummynet.
There are man pages describing all of the above and should be a good
starting plac

Yes:

add it to, otherwise you'll need to add one;

Hi Nick,
Thanks for the testing, I am glad I could help. Please note that by setting:
static int igb_num_queues = 1;
You are effectively only using 1 TX queue from the hardware (instead of
4 or 8) so this might not be applicable to a generic kernel without ALTQ.
Best regards,
Karim.

Hi, this is based on the the understanding that the SS_NBIO is a
socket state, and not a state of the socket buffer.

Hi Nick,
Unfortunately I do not have a FBSD 9 box around where I can compile and
test this so bear with me as this is pretty much straight out of looking
at the source code directly (i.e it might not even compile).
But if your desperate please try the following (untested) patch (applied

Hi Nick,
You need to set the ALTQF_READY flag inside the igb driver. Make sure
you have something like this in if_igb.c:
ifp->if_start = igb_start;
IFQ_SET_MAXLEN(&ifp->if_snd, adapter->num_tx_desc - 1);
ifp->if_snd.ifq_drv_maxlen = adapter->num_tx_desc - 1;
IFQ_SET_READY(&ifp-

Hi Nick,
Can you verify that you have at least one of those options in your
kernel config file:
ALTQ_CBQ
ALTQ_PRIQ
ALTQ_HFSC
