Invalid parameter macaddress on Network::Bond::Static[bond0]

[khorsmann]

Hello,

i try to add an "fake" mac address because i see this error message in dmesg:

bond0: the permanent HWaddr of eno1 - 08:94:ef:ff:xx:yy - is still in use by bond0 - set the HWaddr of eno1 to a different address to avoid conflicts

System: CentOS7 7.4.xx

An old blog-post said that the message is harmless but can push up an issue that bond0 is prefering the (in my case) first slave mac and the first slave interface.

An nice "fake-mac" snippet could be:

echo macaddr=$(echo $(hostname -f)-bond0|md5sum|sed 's/^\(..\)\(..\)\(..\)\(..\)\(..\).*$/02:\1:\2:\3:\4:\5/')
