  ixgbe: this statement may fall through warnings with gcc
  
  The recent gcc versions (7 and 8 at least) can check for switch case
  statements for fall through (implicit-fallthrough). When fall through
  is intentional, the default method for warning suppression is to place
  comment /* FALLTHROUGH */ exactly before next case statement.
