Subject: nfp: flower: fix implicit fallthrough warning
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9bad65e51549d89b388f9c677d7527eede419e18;p=openwrt%2Fstaging%2Fblogic.git

nfp: flower: fix implicit fallthrough warning

The nfp_flower_copy_pre_actions function introduces a case statement with
an intentional fallthrough. However, this generates a warning if built
with the -Wimplicit-fallthrough flag.

Remove the warning by adding a fall through comment.
