Hi Jason and Doug, This patchset adds a 'sleepable' flag to create/destroy address handle flows in order to allow drivers to wait for device completion instead of busy polling when possible. Patches #1, #2 add the flag to create/destroy AH callbacks and change all the drivers, patches #3, #4 change bnxt_re driver to make use of the flag and not poll for firmware completion. I had some issues with rdmavt callbacks, it looks like their create_ah function is not matching the callback signature. Not entirely sure if that's intended or not so I didn't change it, let me know what you think about that.
