Match VLAN_VID in TMAC table for mcast flows

Browse Source 
Matching VLAN_VID in TMAC table is mandatory on QMX switches
XGS switches support optional VLAN_VID matching so this patch is effective for both platforms

In addition,
- Take native vlan into account when assigning VLAN for untagged multicast traffic
- Fix a bug that puts wrong eth_type in TMAC table
