Yup, just to be sure you understand the process please take a look at

 - How do the changes posted to netdev make their way into Linux?
 - How often do changes from these trees make it to the mainline Linus
   tree?

here:

https://www.kernel.org/doc/html/latest/networking/netdev-FAQ.html#how-do-the-changes-posted-to-netdev-make-their-way-into-linux

But yeah, I think we can go back to posting all 15 patches as one
series. Let's see if Andrew has any feedback on the v2.

Sorry for the confusion!
