Flexible VLAN tagging and native VLAN ID support for link aggregation

We support flexible VLAN tagging and native VLAN ID for link aggregation. Flexible VLAN tagging supports transmission of 802.1Q VLAN single-tag and dual-tag frames on logical interfaces on the same Ethernet port. We've also enhanced the Link Aggregation page for better experience: 

• Renamed the VLAN Tagging column as VLAN Tagging Type. 
• On the Add AE Interface page: 
• Renamed General Settings as General. 
• Renamed Advanced Settings as Link Aggregation Control Protocol (LACP). 
• Added VLAN tagging types.
