--- Comment #3 from Marek Zarychta <zarychtam@plan-b.pwste.edu.pl> ---
FYI something was broken between 11.0-STABLE r318137 and 11.1-PRERELEASE
r318590.
In our setup, TCP MD5 signed packets originate from vlan interface created =
on
lagg interface, so the issue could be VLAN or LAGG specific.=20
I don't know if freshest PRERELEASE works fine. For sure r318137 recompiled
from sources works correctly, although just after the bootup, some packets =
with
bad signatures occurred:

# netstat -sp tcp | grep signature
        8794 packets with matching signature received
        18 packets with bad signature received
        0 times failed to make signature due to no SA
        1 time unexpected signature received
        1 time no signature provided by segment

--=20
