docs: aoe: convert docs to ReST and rename to *.rst
There are only two files within Documentation/aoe dir that are
documentation. The remaining ones are examples and shell
scripts.
Convert the two AoE files to ReST format, and add the others
as literal, as they're part of the documentation.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

If the data is -being written from a dirty page in order to free that page, and if -there are no other pages available, then deadlock may occur when a -free page is needed for the sk_buff allocation. This situation has -not been observed, but it would be nice to eliminate any potential for -deadlock under memory pressure. - -Because ATA over Ethernet is not fragmented by the kernel's IP code, -the destructor member of the struct sk_buff is available to the aoe -driver.
