I may be entirely missing what you are raising as a problem, but visiting

https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/

shows that their primary branch is called 'master'.

The verbose report left by "git fetch" tells us what branch they have is used to update what branch we have, so I think this is pretty much expected.

I am puzzled by your mention of 'net-next' (local).

You may have

    [branch "net-next"]
        remote = net-next
	merge = master

and that is where your expectation on the local may be coming from, but it wouldn't be all that relevant to "git fetch". The update of the local branch will happen long after "git fetch" is done.

Besides, you may have more than one local branch that is forked from the same remotes/net-next/master remote-tracking branch and at that point "git fetch" wouldn't be able to tell which one of these multiple local branches to show.
