[RFC 0/7] Introduce FreeBSD macros for SAFE iteration

[Stephen Hemminger <stephen@networkplumber.org>]

This series adds common macros for safe iteration over lists.
It is a subset copy of the macros from FreeBSD that are
missing from the Linux header sys/queue.h

Chose this over several other options:
  - let each driver define their own as needed.
    One Intel driver got it wrong, others will as well.
  - rename all the queue macros to RTE_XXX variants.
    Seems like useless renaming and confusion.
  - Several distros have libbsd package with the correct macros.
    But adding yet another dependency to DPDK would be annoying
    for something this basic.

There are more macros in FreeBSD header that could be useful,
but we can add those later as needed here.

Stephen Hemminger (7):
  eal: add queue macro extensions from FreeBSD
  net/qede: fix use after free
  bus/fslmc: fix use after free
  net/bnxt: fix use after free
  net/iavf: replace local version of TAILQ_FOREACH_SAFE
  vhost: replace open coded TAILQ_FOREACH_SAFE
  raw/ifpga: use EAL version of TAILQ_FOREACH_SAFE
