Instead of using flow stats per NUMA node, use it per CPU. When using
megaflows, the stats lock can be a bottleneck in scalability.

This patch adds hardware offload capability to cls_bpf classifier,
similar to what have been done with U32 and flower.

Hi!
Dave, this set depends on bitfield.h which is sitting in the
pull request from Kalle. I'm expecting buildbot to complain
about patch 8, please pull wireless-drivers-next before applying.
v4:
- rename parser -> analyzer;
- reorganize the analyzer patches a bit;
- use bitfield.h directly.
Implement .stats_update() callback. The implementation
is generic and can be reused by other simple actions if
needed.

Add translator for JITing eBPF to operations which
can be executed on NFP's programmable engines.
Signed-off-by: Jakub Kicinski

v4:
- use bitfield.h directly.
v3:
- don't clone the program for the verifier (no longer needed);
- temporarily add a local copy of macros from bitfield.h.
NOTE:
Advanced JIT compilers and translators may want to use
eBPF verifier as a base for parsers or to perform custom
checks and validations.
Add ability for external users to invoke the verifier
and provide callbacks to be invoked for every intruction
checked. For now only add most basic callback for
Periodically poll stats and call into offloaded actions
to update them.

Add hardware bpf offload on our smart NICs. Detect if
capable firmware is loaded and use it to load the code JITed
with just added translator onto programmable engines.
This commit only supports offloading cls_bpf in legacy mode
(non-direct action).

Add missing ABI defines and eBPF instructions to allow

Move verifier's internal structures to a header file and
prefix their names with bpf_ to avoid potential namespace
conflicts. Those structures will soon be used by external
analyzers.
Signed-off-by: Jakub Kicinski

v4:
- separate from adding the analyzer;
- squash with the prefixing patch.
Storing state in reserved fields of instructions makes
it impossible to run verifier on programs already
marked as read-only. Allocate and use an array of
per-instruction state instead.
While touching the error path rename and move existing
jump target.

When running as parser interpret BPF_LD | BPF_IMM | BPF_DW

Add cls_bpf support for the TCA_CLS_FLAGS_SKIP_HW flag.
Unlike U32 and flower cls_bpf already has some netlink

the same flag values as the above.
Unlike U32 and flower reject unknown flags.

Hi,
While adding MDB support to the qca8k dsa driver I found that ipv4 mcast
groups don't always get propagated to the dsa driver. In my setup there
are 2 clients connected to the switch, both running a mdns client. The
.port_mdb_add() callback is properly called for 33:33:00:00:00:FB but

Hi Brenden,
I don't quite understand the semantics of the XDP userspace interface.
We allow XDP programs to be (unconditionally) exchanged by another
program, this avoids taking the link down+up and avoids reallocating
RX ring resources (which is great).
We have two XDP samples programs in sampl
Hi Brenden,

No functional change. Just to avoid the usage of '&~3'.
Also break the line to make it easier to read.
