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
