[dpdk-stable] [PATCH] doc: fix API index

[Thomas Monjalon]

With Doxygen 1.8.18, a warning appears when tagging
the main markdown header with {#index}.
That's why the tag has been removed from the API index in DPDK 20.05.
Unfortunately it makes the index page classified as a standard
"related page" instead of being the "main page".

The tag {#mainpage} could be used instead of {#index}.
Another solution, chosen here, is to specify the main page file
in the Doxygen configuration with the variable USE_MDFILE_AS_MAINPAGE.

Fixes: 76fb8fc486f9 ("doc: fix build with doxygen 1.8.18")

I don't have a system with 1.8.18.
With 1.8.15 (fc31), api/index.html is again populated with this page
and links to this page are restored.

Applied, thanks.

Luca, I saw you marked 76fb8fc486f9 ("doc: fix build with doxygen
1.8.18") for 19.11.3.
So this current patch is a candidate for 19.11.3 too.
