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