vpp-swan: fix function to get sw_if_index
In the current implementation there is a bug in the function responsible for getting software interface index by the name of the interface. Incorrect function is used to send the API message, also the handler with replied message is incorrect. The fix changes function to send dump message and also adds handler with replied message in the correct way. Type: fix Signed-off-by: Gabriel Oginski <gabrielx.oginski@intel.com> Change-Id: Id1a3ba2ce7e92d216907f344431b9e2acb1d5572
