This set of patches came from security review of bnxt driver.
It introduces a set of overflow macros that could be more widely
used in other places in DPDK to check for math overflows.

Stephen Hemminger (6):
  eal: add portable way to check for math overflow
  net/bnxt: fix potential data race
  net/bnxt: avoid potential out of bounds read
  net/bnxt: check for integer overflow in buffer sizing
  net/bnxt: add integer underflow check
  net/bnxt: sanitize max_l2_ctx
