mlxsw: spectrum_dpipe: Add adjacency group size
The adjacency group size is part of the match on the adjacency group and
should therefore be exposed using dpipe.
When non-equal-cost multi-path support will be introduced, the group's
size will help users understand the exact number of adjacency entries
each nexthop occupies, as a nexthop will no longer correspond to a
single entry.
The output for a multi-path route with two nexthops, one with weight 255
and the second 1 will be:
Example:
$ devlink dpipe table dump pci/0000:01:00.0 name mlxsw_adj
pci/0000:01:00.0:
index 0
match_value:
type field_exact header mlxsw_meta field adj_index value 65536
type field_exact header mlxsw_meta field adj_size value 512
type field_exact header mlxsw_meta field adj_hash_index value 0
action_value:
type field_modify header ethernet field destination mac value e4:1d:2d:a5:f3:64
type field_modify header mlxsw_meta field erif_port mapping ifindex mapping_value 3 value 1
index 1
match_value:
type field_exact header mlxsw_meta field adj_index value 65536
type field_exact header mlxsw_meta field adj_size value 512
type field_exact header mlxsw_meta field adj_hash_index value 510
action_value:
type field_modify header ethernet field destination mac value e4:1d:2d:a5:f3:65
type field_modify header mlxsw_meta field erif_port mapping ifindex mapping_value 4 value 2
Thus, the first nexthop occupies 510 adjacency entries and the second 2,
which leads to a ratio of 255 to 1.
