igb cards not be used for production flows, because there is little hope

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

Karim.

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;
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,
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.

Yes:
* you need to add it to conf/options - see if there's an opt_igb.h to
add it to, otherwise you'll need to add one;
* Make sure the driver code includes opt_igb.h;
* Then make sure you make kernel modules using either make buildkernel
KERNCONF=X, or you set the environment appropriately so

Hi Jack,
I think this would help M. Rogers case as we have done something similar
here to circumvent the issue and it seems to work well. I would also add
that when using ALTQ we found it much more stable to set the number of
queues to 1:
static int igb_num_queues = 1;

The if_transmit versus multiqueue thing is orthogonal.
I'm planning to make net80211 and ath(4) use if_transmit instead of
if_start. It won't be a multi-queue driver; I'm actually going down
the path of if_transmit specifically so I can control the TX queue
serialisation and actively _serialise_

Indeed, although ALTQ isn't using if_transmit and doing a simple drop in
