Alb Bonding error i have never seen before

i have been searching google for a solution to this issue

dev_set_mac_address of dev enp2s0 failed! ALB mode requires that the base driver support setting the hw address also when the network device's interface is open

this comes up on my Ubuntu server.

i have 2 interfaces setup in bond mode 6 ALB and i get this error for one of the interfaces not sure what it is. looked though google for a soloution to no avail.

Check the following:


"The balance-alb mode depends on swift ARP trickery to fool the kernel into thinking the two physical interfaces are one by rewriting the MAC address on the fly. So the driver for the interface must support this, and many of them don't. "

The article explains how you can check the driver to see if you are using one that supports the set_mac_address function. I have not found any other references to checking the driver/interface for this support

Worse case, you can use other bonding modes.
