Hi all,
FreeBSD 11.2-STABLE (FreeNAS):
bnxt0: flags=3D8842<BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu =
1500 =

vlan: 1 vlanpcp: 0 parent interface: bnxt0
groups: vlan
No traffic shows when I use tcpdump - either on vlan1 or bnxt0 - simply =
zero.
There must be some broadcast frames flying past even if the switch on =
the
other end should be misconfigured which I doubt ;-)
Same configuration on dozens of servers running fine - this is our first =
system
with bnxt(4).
