Merge branch 'net-ipa-minor-bug-fixes'

Alex Elder says:

====================
net: ipa: minor bug fixes

This series fixes several bugs.  They are minor, in that the code
currently works on supported platforms even without these patches
applied, but they're bugs nevertheless and should be fixed.

Version 2 improves the commit message for the fourth patch.  It also
fixes a bug in two spots in the last patch.  Both of these changes
were suggested by Willem de Bruijn.
