Add a devlink parameter to control the number of large groups in a
autogrouped flow table. The default value is 15, and the range is between 1
and 1024.
The size of each large group can be calculated according to the following
formula: size = 4M / (fdb_large_groups + 1).
Examples:
- Set the number of large groups to 20.
$ devlink dev param set pci/0000:82:00.0 name fdb_large_groups \
cmode driverinit value 20
Then run devlink reload command to apply the new value.
$ devlink dev reload pci/0000:82:00.0
- Read the number of large groups in flow table.
$ devlink dev param show pci/0000:82:00.0 name fdb_large_groups
pci/0000:82:00.0:
name fdb_large_groups type driver-specific
values:
cmode driverinit value 20
