====================
nfp: cleanups and improvements

Main purpose of this set is to get rid of doing potentially long
mdelay()s but it also contains some trivial changes I've accumulated.
First two patches fix harmless copy-paste errors, next two clean up
the documentation and remove unused defines.  Patch 5 clarifies the
interpretation of RX descriptor fields.  Patch 6, by far the biggest,
adds ability to perform FW reconfig asynchronously thanks to which
we can stop using mdelay().
