mlxsw: spectrum_fid: Allow setting and clearing NVE properties on FID
In the device, the VNI and the list of remote VTEPs a packet should be flooded to is a property of the filtering identifier (FID). During encapsulation, the VNI is taken from the FID the packet was classified to. During decapsulation, the overlay packet is injected into a bridge and classified to a FID based on the VNI it came with. Allow NVE configuration for a FID. Currently, this is only supported with 802.1D FIDs which are used for VLAN-unaware bridges. However, NVE configuration is going to be supported with 802.1Q FIDs which is why the related fields are placed in the common FID struct. Since the device requires a 1:1 mapping between FID and VNI, the driver maintains a hashtable keyed by VNI and checks if the VNI is already associated with an existing FID.
