I've run across a strange problem with the igb driver in 8-STABLE - when
I try to do anything with the second igb interface, I get one or more "igb1:
Could not setup receive structures" error messages.
This can be reproduced as simply as booting in single-user mode with an
empty /boot/loader.conf and doing:
ifconfig igb0 up
ifconfig igb1 up
I've tried to track this down, and as far as I can see, this is from some
change introduced between 8.1-RELEASE (igb 1.9.5) and the current 8-STABLE
(igb 2.0.1). When I try it when booting from the 8.1-RELEASE amd64 DVD, I
can bring up both interfaces. When I try it with an 8-STABLE kernel, I get
the error and igb1 is missing the "RUNNING" flag:
igb0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9000
options=1bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4>

I see 3 mbuf_jumbo_page allocation failures from:

mbuf_jumbo_page: 4096, 12800, 12307, 493, 30343, 3
which correspond to the 3 "igb1: Could not setup receive structures" mess-
ages. If I try another "ifconfig igb1 up", I get another console message and
the counter goes to 4. If I bump the kern.ipc.nmbjumbop sysctl to a larger
value, like 15000, I get the same error message when trying to work with the
igb1 device, so I don't think it is a "real" error but indicates a problem
in the driver.
This is on a Supermicro X8DTH-iF, BIOS 2.0a (latest) with a dual on-board
82576. The dev.igb sysctl's for the two ports (excluding 0 values) are at-
tached. Note that most of the igb1 values are zero:

Both ports are cabled to the same Cisco switch. If I swap the cables at
the FreeBSD end between igb0 and igb1, the problem stays with igb1 so I
don't think it is the switch.
I have 3 identical systems, all of which exhibit this same issue. Un-
fortunately, I don't have any other hardware with dual igb's.
I can give a developer root access as well as a web-based remote console
if needed to track this down.
