Replace fragile SSH+jq approach for reading the chassis MAC with a NETCONF query to ietf-hardware:hardware/component[name='mainboard'], reading phys-address directly from the YANG model. Also add until() polling to the chassis MAC and chassis+offset MAC verification steps, consistent with the reset-to-default steps. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
