   4 Subject: [PATCH] LF-697 net: ethernet: freescale: sdk_fman: fix the build
   5  warnings
   6 MIME-Version: 1.0
   7 Content-Type: text/plain; charset=UTF-8
   8 Content-Transfer-Encoding: 8bit
   9
  10 The patch fixes the build warnings by adding the comments 'fall through' to avoid the build warnings
  11 The patch also initializes the value pgid_val to avoid the warning: ‘pgid_val’ may be used uninitialized
  12 The patch should not and will not have any function impact.
