Add struct to store outer part for tunnel rule.
Add vxlan ptype in ipv4 mac bitmap. So when create a vxlan rule, the
ptype group will be valid.

Distinguish inner/outer fields for parse pattern. So FDIR for tunnel
can be more flexible. Enable VXLAN inner/outer L3/L4 different fields
for FDIR.

[Cao, Yahui] 
It seems below code has quite some duplication with code within the else condition
 Can you use a pointer *input_set and *ip to point to the different input_set bits and input_set value,
So that existing code can be reused.

[Cao, Yahui] 
Why use input_set instead of filter->outer_input_set in the VXLAN outer section ?

Yes, you are right. And I will refactor this part in V2. Thanks.
