[PATCH iproute2-next v2 0/3] tc: add the psp action and flower psp matches

[Todd Freed <toddfreed@meta.com>]

This adds tc support for socket-less PSP associations, from the net-next
series:

  https://lore.kernel.org/netdev/20261111005533.6436-1-toddfreed@meta.com

 - The psp action: attach a PSP Tx association to a packet, for the PSP
   device to encrypt on transmit (encap), or remove the PSP Rx state of a
   packet the device decrypted (decap).
 - Flower matches on that Rx state: psp_spi, psp_ver and psp_dev.

The selftests in the kernel series, drivers/net psp.py and tc-testing
psp.json, use them.

The kernel series isn't merged yet. Patch 1 copies its uapi headers, so
that this builds and can be tested with it; it can be replaced by the
regular header sync once the kernel series is merged. Please apply this
series only after the kernel series is merged into net-next. The tc uapi
is unchanged in the kernel series' v2.

Testing: with the kernel series on netdevsim, drivers/net psp.py (57
tests) and tc-testing psp.json (17 tests) pass with this tc.

Changes in v2 (Stephen):
 - psp action: match keywords with strcmp() instead of matches().
 - psp action: reject "decap assoc", and a repeated "assoc".
 - psp action: print psp_action as a string in JSON for any value, and
   only when the kernel reports it.
 - psp action: list "jump" in CONTROL, in the usage and the man page.
 - psp action: check "encap" and "assoc" also with "index", and list the
   bare "index INDEX" form, which references an existing action.
 - flower: parse psp_ver and psp_dev as decimal.

v1: https://lore.kernel.org/netdev/20261112001512.3598626-1-toddfreed@meta.com
