Patchwork won't care. It only makes problems if you send the exact same title without version bump. But for people looking at it version might help, unless you really do something completely different in the new patch.

Since it has a different title, I presumed patchwork site will not understand is the 2nd version of previous patch.

[OpenWrt-Devel] [netifd][PATCH] interface-ip: transfer prefix route ownership to kernel when IPv6 address becomes deprecated
From: Alin Nastac When netifd manages the prefix route directly, it will remove it the moment prefix gets deprecated. This will make it impossible for the target to send ICMPv6 errors back to LAN devices still using the deprecated prefix, thus breaking the L-14 requirement of RFC 7084.
