[P4-dev] reading egress port from register

I am trying to pick the outgoing (a random fashion) from a register, 
where I have stored all the available outgoing ports in the register in 
advance. What I tried to do so far is that reading the register value 
into a metadata field and copy (modify_field) to egress_spec. I am not 
sure whether this is the right way to do.

How can I match this metadata value using a table? how can I do mod 
operation on the register value set?

any help would be great. thanks in advance,
