sock_open return vlan name, but other functions get ifname and vlan id both.
Example, sock_open return enp1s0np2.10. And other functions get parameter that ifname is enp1s0np2.10, vlan_id is 10.
When other functions call get_vlan_name(), get enp1s0np2..10 to vlan name.
So, functions parameter need to change vlan_name instead of ifname and vlan_id.
But little complicated, so changed simplify for now.
