Hi!
I'm building new router using 8.2-PRERELEASE containing new igb(4) driver.
I use SuperMicro SuperServer 5016T-MTFB based on X8STi-F motherboard
with add-on Intel Gigabit ET Dual Port Server Adapter in PCIe slot.
pciconf -lv shows:
i...@pci0:3:0:0: class=0x020000 card=0xa03c8086 chip=0x10c98086 rev=0x01
hdr=0x00
class = network
subclass = ethernet
i...@pci0:3:0:1: class=0x020000 card=0xa03c8086 chip=0x10c98086 rev=0x01
hdr=0x00
class = network
subclass = ethernet
I connect both ports to Cisco 7606 core router and they link
after "ifconfig ibg1 up" command.
But "ifconfig igb1 down" does NOT bring link down:
- ifconfig igb still shows "status: active" (but not UP nor RUNNING);
- LEDs are on (both SuperServer's and Cisco's)
- Cisco also shows interfaces in "up" state.
That's bad as I plan to use EtherChannel/lagg configuration
and need working up/down management.
Driver igb(4) is not compiled into kernel, it's loaded using if_igb.ko.
I've rebuilt kernel module changing if_igb.h to get debugging output:
#define DEBUG_INIT 1
#define DEBUG_IOCTL 1
#define DEBUG_HW 1
Now I have in kernel log after single "ifconfig igb1 down" command:

If I do "ifconfig igb1 up" now, link is brought down for short time then up.
This SuperServer box has two built-in em(4) ports that have not this problem.
How should I fix this?
