[PATCH v7 00/16] DPAA bus/net/mempool/DMA driver fixes and improvements

[Hemant Agrawal]

This series collects a set of correctness fixes, cleanups and feature
additions across the NXP DPAA bus, net, mempool and DMA drivers.

1. Bus/fman infrastructure cleanups (patches 01, 02, 12)
   - bus/dpaa: refine fman naming and fix global scope
   - bus/dpaa: scan max BPID from DTS
   - bus/dpaa: improve log macro and fix bus detection

2. Process-type guards (patch 03)
   - drivers: add process-type guards to prevent segfaults in secondary

3. FQ shutdown hardening (patches 04-08)
   - bus/dpaa: define helpers for qman channel and wq
   - bus/dpaa: shutdown DPAA FQ by fq descriptor
   - bus/dpaa: improve FQ shutdown with channel validation
   - bus/dpaa: enhance DPAA FQ shutdown
   - bus/dpaa: add DPAA cgrid cleanup support

4. net/dpaa improvements (patches 09, 11, 13)
   - net/dpaa: add ONIC port checks
   - net/dpaa: optimize FM deconfig
   - net/dpaa: optimize FMC MAC type parsing

5. Statistics (patch 10)
   - drivers: add BMI Tx statistics

6. mempool/dpaa (patches 14-15)
   - drivers: optimize DPAA multi-entry buffer pool operations
   - drivers: release DPAA bpid on driver destructor

7. dma/dpaa (patch 16)
   - dma/dpaa: add SG data validation and ERR050757 fix

v7 changes:
- Drop three net/dpaa patches from v6 that need further review:
  "net/dpaa: clean Tx confirmation FQ on device stop",
  "net/dpaa: remove redundant FQ shutdown from Rx queue setup",
  "net/dpaa: report error on using deferred start".
- Rebased onto 26.07-rc2.

v6 changes:
- Fix bman_release_fast() in patch 14: replace rte_memcpy() on the
  small bm_bufs[] stack array with memcpy(); the SIMD implementation
  of rte_memcpy reads in 32/64-byte chunks and triggers
  -Warray-bounds with GCC 15 / ASAN builds on the 64-byte array.
  memcpy() is correct here as this is a local stack buffer with no
  DMA or multi-process constraints.

v5 changes:
- Rebased onto current upstream main; resolved conflict in
  drivers/crypto/dpaa_sec/dpaa_sec.c where upstream removed the
  cryptodev_name[] local variable and snprintf() call in
  cryptodev_dpaa_sec_probe() -- patch 03 now uses dpaa_dev->name
  directly in rte_cryptodev_pmd_create().
- Resolved conflict in drivers/net/dpaa/dpaa_ethdev.c where upstream
  removed rte_dpaa_device.eth_dev -- patch 03 now uses
  rte_eth_dev_allocated() to look up the Ethernet device by name.

v4 changes:
- Fix dpaa_bus_dev_compare() to return the strncmp result (previously
  always returned 0, breaking device matching).
- Remove the dead get_tx_port_type() function that triggered a clang
  -Wunused-function CI failure.
- Guard all dpaa_fm_deconfig() call sites against NULL port_handle to
  prevent a NULL dereference on partially initialised interfaces.
- Move the penv variable declaration in dpaa_qdma_init() to the point of
  use (C99 inline), fixing a spurious -Wunused-variable warning during
  bisect of earlier patches in the series.
