[PATCH v4 0/6] use static assert to cathc build errors

[Stephen Hemminger]

This series fixes a couple places where expressions that could not
be evaluated as constant early in compiler passes were used.
Then converts RTE_BUILD_BUG_ON() with static_assert.

static_assert() is more picky about the expression has to
be a constant, which also catches some existing undefined
behavior that pre-existed.

v4 - incorporate review feedback
     add RTE_MIN_T and RTE_MAX_T macros

Stephen Hemminger (6):
  eal: introduce RTE_MIN_T() and RTE_MAX_T() macros
  event/opdl: fix non-constant compile time assertion
  net/sfc: fix non-constant expression in RTE_BUILD_BUG_ON()
  net/i40e: avoid using const variable in assertion
  mempool: avoid floating point expression in static assertion
  eal: replace out of bounds VLA with static_assert
