The "net-next" tag goes into the subject-prefix, i.e.
"[PATCH net-next v3 0/4]" (this is the result of git format-patch
--subject-prefix="PATCH net-next" -v3 --cover-letter.)

The commit title prefix represents the most impacted subsystem, here
"net: dsa: xxx" would map the net/dsa/ or drivers/net/dsa directories.

Other than that, the whole patchset LGTM:
