* Explain the bug(s)

tc hardware stats are not offloaded from some offloaded actions (pedit, sample, skbedit)

* brief explanation of fixes

Implement the necessary callbacks to report back stats for these actions.

* How to test

Configure two mlx5 rep devices and VFs.
Add tc offloaded tc rules with pedit action, and hit that rule with traffic

Bartlomiej,
Do you have some sort of CI that can catch these issues?

I've dropped the "[SRU][F:linux-bluefield][PATCH v1 0/3] Support
hardware stats for tc actions" patchset for now from the master-next
branch (by rebasing the branch).

> Bartlomiej,

We currently don't have CI for automatically build-testing all
submitted patches during review and I've been assuming that the
changes being submitted are actually tested but it doesn't seem to be
always the case (as some submissions don't apply or build). I'll from
now on apply+build test all submissions (I've used to skip it for
smaller, "obviously looking" ones) before acking and applying them.
