Hello,
I would like to add little piece to this as well.
We can reproduce same issue with driver 3.2.12-k
Jan 30 12:59:18 localhost ix0: <Intel(R) PRO/10GbE PCI-Express Network
Driver,
Version - 3.2.12-k> port 0xecc0-0xecdf mem
0xd9d00000-0xd9dfffff,0xd9ff8000-0xd9ffbfff irq 40 at device 0.0 numa-domain 0
on pci2
having lagg1
lagg1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu
1500
options=e407b9<RXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,VLAN_HWTSO,RXCSUM_IPV6,TXCSUM_IPV6>
ether a0:36:9f:3e:57:18
inet 61.0.0.24 netmask 0xff000000 broadcast 61.255.255.255
nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
media: Ethernet autoselect
status: active
groups: lagg
laggproto failover lagghash l2,l3,l4
laggport: ix0 flags=5<MASTER,ACTIVE>
laggport: ix1 flags=0<>
we use simple script to reproduce this:
# more a.sh
#!/bin/sh
while true; do
ifconfig $1 down
echo next $1
ifconfig $1 up
#sleep 1
done
# sh a.sh ix0
After about 30-50 loops, we can find ix0 interface with flag UP, but with
'no
carrier' status
ix0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=9400b8<VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,VLAN_HWTSO,NETMAP>

=============
Same result is done also when netmap is not involved; script will take ix0 down
too
# ifconfig ix0
ix0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=e407b9<RXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,VLAN_HWTSO,RXCSUM_IPV6,TXCSUM_IPV6>
ether a0:36:9f:3e:57:18
hwaddr a0:36:9f:3e:57:18
nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
media: Ethernet autoselect
status: no carrier
FYI, we do temporary downgrade of driver to 3.1.13-k where issue is not
present.
If I can help with any additional testing, let me know.
Best Regards,
Peter
