interfaces: T6592: moving an interface between VRF instances failed
To reproduce: set vrf name mgmt table '150' set vrf name no-mgmt table '151' set interfaces ethernet eth2 vrf 'mgmt' commit set interfaces ethernet eth2 vrf no-mgmt commit This resulted in an error while interacting with nftables: [Errno 1] failed to run command: nft add element inet vrf_zones ct_iface_map { "eth2" : 151 } The reason is that the old mapping entry still exists and was not removed. This commit adds a new utility function get_vrf_tableid() and compares the current and new VRF table IDs assigned to an interface. If the IDs do not match, the nftables ct_iface_map entry is removed before the new entry is added. (cherry picked from commit 452068ce78581bb6fba2df4dba197e95b9aeb33d) # Conflicts: # python/vyos/ifconfig/interface.py # python/vyos/utils/network.py
