[PATCH v2 00/14] common/sfc_efx/base: fix code analysis issues

[Ivan Malov <ivan.malov@arknetworks.am>]

This series addresses code analysis defects in the
common/sfc_efx/base library.

The first four patches fix excessive stack consumption in
MCDI helper functions, each exceeding 1 KB on-stack, by
switching to heap-allocated payload buffers.

The remaining ten patches correct SAL annotations, add NULL
checks across netport and filter helpers, resolving
uninitialised memory, buffer overrun, and potential
dereference issues. The final patch widens loop
variable types to address a CodeQL warning.


v2:

- note for the future AI reviews: apply this on top of
  the 'next-net-main' branch

- addressed https://mails.dpdk.org/archives/dev/2026-August/343072.html
  -- fixed the MAC_STATISTICS_DESCRIPTOR_OUT_MORE_ENTRIES accessor
  -- fixed the FEC hardware enum selection from the software mask
  -- remaining notes do not seem to point at factual defects
