====================
net: ipa: a mix of patches

This series includes a mix of things things that are generally
minor.  The first four are sort of unrelated fixes, and summarizing
them here wouldn't be that helpful.

The last three together make it so only the "configuration data" we
need after initialization is saved for later use.  Most such data is
used only during driver initialization.  But endpoint configuration
is needed later, so the last patch saves a copy of that.  Eventually
we'll want to support reconfiguring endpoints at runtime as well,
and this will facilitate that.
