In the erif table, the 1000 is the max not current usage. I do not have
1000 interfaces:
$ ip -br li sh | wc -l
597
$ devlink dpipe table dump pci/0000:03:00.0 name mlxsw_erif
...
index 503
match_value:
type field_exact header mlxsw_meta field erif_port mapping ifindex
mapping_value 601 value 503
action_value:
type field_modify header mlxsw_meta field l3_forward value 1
The host4 table it is current size with no maximum.
The meaning of table size needs to be consistent across tables.
