Hi,

You should not use polling for RTL8188EE - it was mainly used for
RTL8192C* (since there is no documented way to get events from it)
and can be enabled on RTL881(1,2)A (but just is not needed here).

Look into rtwn/rtl8188e/r88e_rx.c - I think you can call
r88e_ratectl_tx_complete() and/or r88e_handle_c2h_report() indirectly
 from rtwn_pci_intr() when C2H event arrives.
