[PATCH bpf-next v2] bpf, docs: Use internal linking for link to netdev subsystem doc

[Bagas Sanjaya]

Commit d56b0c461d19da ("bpf, docs: Fix link to netdev-FAQ target")
attempts to fix linking problem to undefined "netdev-FAQ" label
introduced in 287f4fa99a5281 ("docs: Update references to netdev-FAQ")
by changing internal cross reference to netdev subsystem documentation
(Documentation/process/maintainer-netdev.rst) to external one at
docs.kernel.org. However, the linking problem is still not
resolved, as the generated link points to non-existent netdev-FAQ
section of the external doc, which when clicked, will instead going to
the top of the doc.

Revert back to internal linking by simply mention the doc path while
massaging the leading text to the link, since the netdev subsystem doc
contains no FAQs but rather general information about the subsystem.

Fixes: d56b0c461d19da ("bpf, docs: Fix link to netdev-FAQ target")
Fixes: 287f4fa99a5281 ("docs: Update references to netdev-FAQ")

 Changes since v1 [1]:

   * Use plain doc path for internal linking
   * Edit the surrounding text to mention what the target is about

 There is an unresolved question: Is this cross-ref fixup should be made
 against bpf tree instead, because the original problem is also seen there?
 If so, I will do the fix against that tree instead.
