Before this patch we had cases that either sent notifications when there were in fact no changes (e.g. non-existent vlan delete) or didn't send notifications when there were changes (e.g. vlan add range with an error in the middle, port flags change + vlan update error). This patch sends down a boolean to the functions setlink/dellink use and if there is even a single configuration change (port flag, vlan add/del, port state) then we always send a notification. This is all done to keep backwards compatibility with the opportunistic vlan delete, where one could specify a vlan range that has missing vlans inside and still everything in that range will be cleared, this is mostly used to clear the whole vlan config with a single call, i.e. range 1-4094.
