[net-next,00/11] octeontx2: Rework MCAM flows management for VFs

Message

Subbaraya Sundeep Aug. 17, 2021, 4:44 a.m. UTC

From Octeontx2 hardware point of view there is no
difference between PFs and VFs. Hence with refactoring
in driver the packet classification features or offloads
can be supported by VFs also. This patchset unifies the
mcam flows management so that VFs can also support
ntuple filters. Since there are MCAM allocations by
all PFs and VFs in the system it is required to have
the ability to modify number of mcam rules count
for a PF/VF in runtime. This is achieved by using devlink.
Below is the summary of patches:

Patch 1,2,3 are trivial patches which helps in debugging
in case of errors by using custom error codes and
displaying proper error messages.

Patches 4,5 brings rx-all and ntuple support
for CGX mapped VFs and LBK VFs.

Patches 6,7,8 brings devlink support to
PF netdev driver so that mcam entries count
can be changed at runtime.
To change mcam rule count at runtime where multiple rule
allocations are done sorting is required.
Also both ntuple and TC rules needs to be unified.

Patch 9 is related to AF NPC where a PF
allocated entries are allocated at bottom(low priority).

On CN10K there is slight change in reading
NPC counters which is handled by patch 10.

Patch 11 is to allow packets from CPT for
NPC parsing on CN10K.


Thanks,
Sundeep
