Same problem here on Dell PowerEdge R740xd running 11.2-RELEASE-p4, sources
modified to include latest mrsas drviers (DELL PERC H740P).

I can attach ix1 to lagg0 later, after system boot... doing this within rc.conf
(in pair with ix0) does not work, ix1 shows 'no carrier' and it doesn't change
it's state after removing from lagg0, interface down/up.

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:  port 0xecc0-0xecdf mem
0xd9d0-0xd9df,0xd9ff8000-0xd9ffbfff irq 40 at device 0.0 numa-domain 0
on pci2

having lagg1

lagg1: flags=8843 metric 0 mtu 1500
   
options=e407b9
ether a0:36:9f:3e:57:18
inet 61.0.0.24 netmask 0xff00 broadcast 61.255.255.255
nd6 options=29
media: Ethernet autoselect
status: active
groups: lagg
laggproto failover lagghash l2,l3,l4
laggport: ix0 flags=5
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 metric 0 mtu 1500
   
options=9400b8
ether a0:36:9f:3e:57:18
hwaddr a0:36:9f:3e:57:18
nd6 options=29
media: Ethernet autoselect
status: no carrier
plugged: SFP/SFP+/SFP28 10G Base-SR (LC)
vendor: OEM PN: SFP-10G-SR SN: IN140317016 DATE: 2014-03-20
module temperature: 30.60 C Voltage: 3.29 Volts
RX: 0.38 mW (-4.10 dBm) TX: 0.41 mW (-3.85 dBm)

SFF8472 DUMP (0xA0 0..127 range):
03 04 07 10 00 00 50 FF 00 00 00 06 67 02 00 00
08 03 00 1E 4F 45 4D 20 20 20 20 20 20 20 20 20

53 52 20 20 20 20 20 20 41 20 20 20 03 52 00 BA
00 3A 00 00 49 4E 31 34 30 33 31 37 30 31 36 20
20 20 20 20 31 34 30 33 32 30 20 20 68 FA 03 07
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

==

Same result is done also when netmap is not involved; script will take ix0 down
too

# ifconfig  ix0
ix0: flags=8843 metric 0 mtu 1500
   
options=e407b9
ether a0:36:9f:3e:57:18
hwaddr a0:36:9f:3e:57:18
nd6 options=29
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

Until I get confirmation from a failure case, I'm not going to do anything with
this at this time.

(In reply to Sean Bruno from comment #19)
I'm not saying it won't help, but it also opens the door for the reasons we
moved it to the beginning of attach() in the first place.  The firmware tends
to not honor the synchronization bits until the driver has taken over (via the
DRV_LOAD bit).
