--- Comment #49 from Peter Vanek <pv@efficientip.com> ---
Hello all,

Just brief summary of our test yesterday:
Network Adapter X520

1. issue re-tested on default kernel

FreeBSD testing-host 11.2-STABLE FreeBSD 11.2-STABLE #274 r345055M: Tue Mar=
 12
18:46:49 UTC 2019

ix0 card will stay in down after few rounds of up and down.

Issue present - OK

=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D

2. Applied patch

Script executing down/up on both ix0 and ix1 for 1000 times, waiting 2 seco=
nds
sleep and displaying status of both interfaces
then continuing in next 1000 times of down/up

After few hours of stressing... result is good and we have both ix0 and ix1
full up and functional.

One more time thanks @Piotr for passing this patch to here.

Best Regards,
Peter
