This seems fine.

I don't think this has anything to do with struct local_info change.

This sounds odd.. Are you sure that the modules were from the same build
in both of these tests? Please add the last_data_rx line and make sure

'make modules'). After this, make sure that none of the Host AP modules
are loaded (lsmod | grep hostap) and if any are, unload them with rmmod.
Finally, load the newly built modules manually with insmod from the
build tree just to make sure you are loading the correct version (insmod
