The previous Kconfig patch led to some other build errors as

Thank you for looking at that!
I had the same issue and I was going to propose a similar fix with one
small difference, please see below.

Should we have here CONFIG_SKB_EXTENSIONS instead of CONFIG_NET?
It is valid to use NET thanks to your commit 85ce50d337d1 ("net: kcov:
don't select SKB_EXTENSIONS when there is no NET") that links
SKB_EXTENSIONS with NET for KCOV but it looks strange to me to use a
"non direct" dependence :)
I mean: here below, skb_ext_add() and skb_ext_find() are called but they
are defined only if SKB_EXTENSIONS is enabled, not only NET.
But as I said, this patch fixes the issue. It's fine for me if we prefer
to use CONFIG_NET.

(Small detail if you post a v2: there is an extra space between "&&" and
