Jiri says:
Currently, an ERP set is created for each region according to rules
inserted and order of their insertion. However that might lead to
suboptimal ERP sets and possible unnecessary spillage into C-TCAM.
This patchset aims to fix this problem and introduces periodical checking
of used ERP sets and in case a better ERP set is possible for the given
set of rules, it rehashes the region to use the better ERP set.
Patch 1 prepares devlink params infra in order to fix the
init/fini sequences.
Patch 2 implements hints infra in objagg library.
Patch 3 fixes a typo
Patch 4 adds number of root objects directly into objagg stats.
Patches 5-7 do split of multiple structs in Spectrum TCAM code.
Patch 8 introduces initial implementation of ERP rehash logic,
according to objagg hints.
Patch 9 adds hints priv passing trought the layers.
Patch 10 adds multi field into PAGT reg. (new patch)
Patch 11 implements actual region rules migration in TCAM code.
Patch 12 adds a devlink param so user is able to control
rehash interval.
Patch 13 adds couple of tracepoints in order to track
rehash procedures.
Patch 14 adds a simple selftest to test region rehash.
