hostap_get_wireless_stats() is a static function of hostap.o module and
you cannot call it from hostap_{cs,plx,pci}.o module, hostap_hw.c is
part of that module.. You would need to change that function to be
non-static and export its symbol to allow it to be called from other
kernel modules.

Another possibility wuld be to use dev->get_wireless_stats function
pointer. hostap.o module registers that to point to
hostap_get_wireless_stats(), so you should be able to call
dev->get_wireless_stats() from hostap_hw.c. Just make sure that you will
use the default interface and not wlan#ap or any wds interface since
they set this function pointer to NULL..
