The resulting priorities are as follows:
IPv6 IPv4
routed normal routed normal
max 4096(+3) 2048(+3) 4096(+3) 2048(+3)
min 3072 1024 3840 1792
Where min is for a policy between two single hosts and max is
for /0 on both ends (lower priorities are preferred by the kernel).
(+3) applies for cases where no protocol and no ports are defined.
