As described in commit 3b81a4e ("[ena] Provide a host information
page"), we currently report an operating system type of "Linux" in
order to work around broken versions of the ENA firmware that will
fail to create a completion queue if we report the correct operating
system type.
As of September 2024, the ENA team at AWS assures us that the entire
AWS fleet has been upgraded to fix this bug, and that we are now safe
to report the correct operating system type value in the "type" field
of struct ena_host_info.
The ENA team has also clarified that at least some deployed versions
of the ENA firmware still have the defect that requires us to report
an operating system version number of 2 (regardless of operating
system type), and so we continue to report ENA_HOST_INFO_VERSION_WTF
in the "version" field of struct ena_host_info.
Add an explicit warning on the previous known failure path, in case
some deployed versions of the ENA firmware turn out to not have been
upgraded as expected.
