Ticket: CM-8866 Reviewed By: Roopa Testing Done: added support for: * bond-lacp-bypass-allow (0|1) * bond-use-carrier (0|1) * bridge-mcqifaddr (0|1) * bridge-mcquerier (0|1) * bridge-mcrouter (0|1) * bridge-mcsnoop (0|1) * bridge-portmcrouter (0|1) * link-autoneg (off|on) * vxlan-learning (off|on) these 2 are not yet supported by ifupdown2: * bond-lacp-bypass-all-active (0|1) * bond-lacp-fallback-allow (0|1) This one is left untouched. yes/no doesn't make sense for this attribute. * bond-lacp-rate (0|1) Signed-off-by: Julien Fortin <julien@cumulusnetworks.com>
