Support rte flow priority attribute for DCF switch filter.
The rules with same patterns couldn't be created at the same
time since they were related to the same recipe. This patch
supports flow priority to create different recipes for this
situation. Only priority 0 and 1 are supported and higher value
denotes higher priority.

for example:
1. flow create 0 priority 0 ingress pattern eth / ipv4 dst is
192.168.0.1 / end actions vf id 1 / end
2. flow create 0 priority 1 ingress pattern eth / ipv4 dst is
192.168.0.2 / end actions vf id 2 / end

These two rules can be created at the same time in DCF switch filter.
And priority of rule 2 is higher.

Support rte flow priority attribute for DCF switch filter.
The rules with same patterns couldn't be created at the same
time since they were related to the same recipe. This patch
supports flow priority to create different recipes for this
situation. Only priority 0 and 1 are supported and higher value
denotes higher priority.

for example:
1. flow create 0 priority 0 ingress pattern eth / ipv4 dst is
192.168.0.1 / end actions vf id 1 / end
2. flow create 0 priority 1 ingress pattern eth / ipv4 dst is
192.168.0.2 / end actions vf id 2 / end

These two rules can be created at the same time in DCF switch filter.
And priority of rule 2 is higher.

Support rte flow priority attribute for DCF switch filter.
The rules with same patterns couldn't be created at the same
time since they were related to the same recipe. This patch
supports flow priority to create different recipes for this
situation. Only priority 0 and 1 are supported and higher value
denotes higher priority.

for example:
1. flow create 0 priority 0 ingress pattern eth / ipv4 dst is
192.168.0.1 / end actions vf id 1 / end
2. flow create 0 priority 1 ingress pattern eth / ipv4 dst is
192.168.0.2 / end actions vf id 2 / end

These two rules can be created at the same time in DCF switch filter.
And priority of rule 2 is higher.

Support rte flow priority attribute for DCF switch filter.
When a packet is matched by two rules, the behavior of it
is not defined. This patch supports flow priority to create
different recipes for this situation. Only priority 0 and 1
are supported and higher value denotes higher priority.

for example:
1. flow create 0 priority 0 ingress pattern eth / vlan tci
is 2 / vlan tci is 2 / end actions vf id 2 / end
2. flow create 0 priority 1 ingress pattern eth / vlan /
vlan / ipv4 dst is 192.168.0.1 / end actions vf id 1 / end

These two rules can be created at the same time in DCF switch
filter and priority of rule 2 is higher. Packet hits rule 2
when two conditions of rules are satisfied.
