v2:
sent mistakely as RFC - remove RFC tag, no functional changes

v1:
This patch series adds port affinity matching for bonded ports and
refactors queue management to support the new port affinity snippets.
This refactoring also enables other snippets that require access to
the queue number to utilize it more easily.

It also introduces support for jumping to specific flow groups,
with three new snippets demonstrating this feature.
