Problem
For vswitch status is not displayed in the WebUI
Solution
Made changes to show the connected interface status for each vSwitch. So that we know if the vSwitch is Up/Down

Tested with the Test data :

switch name vs1:

                port3:

                    Link detected: no

                    Speed: Unknown!

            switch name vs2:

                port2:per

                    Link detected: no

                    Speed: Unknown!

                port1:

                    Link detected: yes

                    Speed: 10000Mb/s

                bond0:

                    port4:

                        Link detected: no

                        Speed: Unknown!

                    port5:

                        Link detected: no

                        Speed: Unknown!

            switch name vs3:
Example JSON response sent to UI:

  'bonds': [], 'name': 'vs1', 'mode': 'Native'}, 

  {'ports': 

  [{'port_name': 'port2', 'link_status': 'Down'}, 

  {'port_name': 'port1', 'link_status': 'Up'}], 

  'bonds': [{'bond_name': 'bond0', 

  'ports_info': [{'port_name': 'port4', 'link_status': 'Down'}, {'port_name': 'port5', 'link_status': 'Down'}]

  }], 'name': 'vs2', 'mode': 'Native'}
