[PATCH net-next v3 0/3] Extend packet socket selftests

[Joe Damato <joe@dama.to>]

Greetings:

I was looking around the packet socket code and noticed there were a few
features that could be tested by extending the existing packet socket
tests.

I extended the test to test stats, drops, and auxdata and re-ran the tests.
The existing and new tests passed.

Thanks,
Joe

v3:
  - Patch 3 updated to prevent combining test_auxdata and test_drops.
  - Patch 3 updated to include an aligned(8) for the cmsg to ensure (1) buffer
    alignment for cmsg struct fields and (2) aligned payload access.

v2: https://lore.kernel.org/netdev/20260403233240.178948-1-joe@dama.to/
  - patch 2: remove argument from do_tx and use global instead
  - patch 3: add argument to do_rx to specify if the socket is a packet
    socket. factored out the aux data check into its own function for
    readability.
