Disable TSO & LRO in /etc/rc.conf

--------------------- /etc/rc.conf ---------------------
# IPv4 Virtual Function
ifconfig_ixv0="inet your_ipv4/24 -tso4 -tso6 -lro -vlanhwtso"
defaultrouter="ipaddress_of_your_ipv4_router"

# IPv6 Virtual Function
ifconfig_ixv0_ipv6="inet6 your_ipv6/64 -tso4 -tso6 -lro -vlanhwtso"
ipv5_defaultrouter="ipaddress_of_your_ipv6_router%ixv0"
--------------------------------------------------------

so far I understand, no TSO / LRO improve network performance as well on vSphere 6.7.

Now, the Environment runs smooth and stable.

Just add

hw.pci.honor_msi_blacklist=0

to /boot/loader.conf -> reboot-> issue fixed !

So just to be clear this is in the guest VM right?
