Hi, This patchset is the third iteration [1] [2] [3] to introduce a kernel intermediate (IR) to express ACL hardware offloads.
On v2 cover letter you had:
"""
However, cost of this layer is very small, adding 1 million rules via
tc -batch, perf shows:
0.06% tc [kernel.vmlinux] [k] tc_setup_flow_action
"""
The above doesn't include time spent on children calls and I'm worried
about the new allocation done by flow_rule_alloc(), as it can impact
rule insertion rate. I'll run some tests here and report back.
