Later on the same code is going to be needed for deltas as well. So push
the procedures related to increment and decrement of num_ctcam_erps
into a separate helpers.

No need to do key encoding again in
mlxsw_sp_acl_atcam_12kb_lkey_id_get(). Instead of that, introduce
a new helper that would just clear unused blocks.

Jiri says:
The Spectrum-2 hardware has limitation number of ERPs per-region. In
order to accommodate more masks than number of ERPs, the hardware
supports to insert rules with delta bits. By that, the rules with masks
that differ in up-to 8 consecutive bits can share the same ERP.

Since two remaining users of mlxsw_afk_encode() do not specify
block ranges to work on, remove the args. Also, key/mask is always
non-NULL now, so skip the checks.

Currently the ERPs are tracked internally in a hashtable. Benefit from
the newly introduced objagg library and use it to track ERPs. At this
point, there is no nesting of objects done, as the delta_create callback
always returns -EOPNOTSUPP. On the way, add "mask" into ERP mask
From: Jiri Pirko
This lib tracks objects which could be of two types:
1) root object
2) nested object - with a "delta" which differentiates it from
the associated root object
The objects are tracked by a hashtable and reference-counted. User is

The device requires that the master mask of each region will be
composed from a logical OR between all the unmasked bits in the region.
Currently, this is just a logical OR between all the eRPs used in the

Allow ERP sharing for multiple mask. Do it by properly implementing

rules in A-TCAM.

So a I mentioned during the presentation for the af_xdp zero copy I
think it's pretty important to be able to close the device and get back
the affected memory. One way would be to unmap the DMA memory from
userspace and map in some other memory. It's tricky since you need
to also replace the
