Kevin,
as the commit title says, the patch is mostly about using the advertized maximum
number of entries in the I/O queues rather than using a fixed number (256). In
addition, the patch caps the number of entries in the I/O queues to 256 since
from my testing, SeaBIOS was oom-ing when attempting to allocate more.
I'm going to repost with a more verbose commit message.
