[PATCH v2 0/5] net/bnxt: interrupt handling, external mbuf and stability fixes

[Mohammad Shuab Siddique]

From: Mohammad Shuab Siddique <mohammad-shuab.siddique at broadcom.com>

This series addresses interrupt handling, external memory, and crash bugs:

 - Fix incorrect completion validation for NQEs and RX completions causing
   excess interrupts
 - Use buf_addr instead of IOVA for mbufs from external memory pools
 - Skip IOVA range check for external mbuf head nodes to avoid false failures
 - Add null checks to prevent segfaults when accessing uninitialized structures
 - Fix segfault on exit when bonded ports are present, by checking whether
   ethdev has already freed the RX/TX queue arrays

All patches carry Fixes: tags and Cc: stable at dpdk.org.

Note: this series depends on series "net/bnxt: ULP stats timer and PTP".

Changes in v2:
 - Patch 1/5: replace printf() with PMD_DRV_LOG_LINE() (DPDK logging standard)
 - Patch 2/5: replace custom bnxt_mbuf_buf_addr() with rte_pktmbuf_mtod_offset()
