> Priority discovery installs temporary drop flows to probe supported flow
> priorities. These flows match a wildcard Ethernet pattern, so they can
> also match real traffic while discovery is running. On shared devices this
> may temporarily drop kernel traffic and cause TCP connection timeouts.
> 
> Constrain the probe flows to match both source and destination MAC
> addresses as ff:ff:ff:ff:ff:ff. This keeps the rule valid for discovery
> while avoiding matches on normal Ethernet traffic.

It does not compile in all conditions.
