Merge branch 'net-ipa-small-collected-improvements'

Alex Elder says:

====================
net: ipa: small collected improvements

This series contains a somewhat unrelated set of changes, some
inspired by some recent work posted for back-port.  For the most
part they're meant to improve the code without changing it's
functionality.  Each basically stands on its own.
