I can't tell you what performance hit, that depends upon your
application, it will hit TCP apps harder than UDP because UDP can't take
advantage of it at all. The performance hit will be highest in net
centric apps like routers.
apt install ethtool
ethtool --offload eth0 rx off tx off

Title:
Intel Ethernet I218-V [8086:15a1] Subsystem [1043:85c4] detected
Hardware Unit Hang
Status in linux package in Ubuntu:
Expired
Status in linux source package in Bionic:

Bug description:
With Bionic kernel 4.15.0-15 and 4.15.0-17 I am experiencing periodic
hanging of the LAN connection. This is happening on an Asus X99-DELUX
motherboard, controller specifications:
Intel® I218V, 1 x Gigabit LAN Controller(s)
Intel® I211-AT, 1 x Gigabit LAN
Dual Gigabit LAN controllers- 802.3az Energy Efficient Ethernet (EEE)
appliance
Support Teaming Technology
ASUS Turbo LAN Utility
The CPU is an i7-6850 and it is configured with 128GB of DDR4 RAM.
This machine has a number of Qemu/KVM virtual guests and is using a software
bridge to share the interface.
This did not happen with 17.10 and 4.13.0 kernel. It is happening on
multiple machines here.
Here are the messages from dmesg:
