  This series fixes a couple places where expressions that could not
be evaluated as constant early in compiler passes were used. And 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.

Stephen Hemminger (5):
  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
