Hmm, just went back and looked again, I'm not sure of the precise
behavior you are going for - I am assuming it is to copy everything
from the vif to the tap.  One other issue you could run into here if
some value is set on the tap but not the vif:

Before:
vxid: {}
txid: {'attached-mac': 'aa:bb:cc:dd:ee:ff'}

set_external_id('Interface', 'tap_name', 'attached-mac', None)

After:
vxid: {}
txid: {'attached-mac': None}

Which would cause an error with set_external_id, based upon
what you said earlier.

You could fix this by doing something like

  if k in vxid and vxid[k] != txid.get(k):
    set_external_id("Interface", tap_name, k, vxid[k])
