Subject: Where does rtlwifi/rtl8188ee identifies interrupt type?

Hi all,

I am reading through the rtlwifi code, specifically rtl8188ee code. I
am trying to find the driver handles interrupts, reads from the card
and identifies what type of interrupt it receives.

I believe it will utilize the REG_HISR and REG_HIMR registers, but
only see writes to those register values, not reads which I was
expecting.

Any ideas? Thanks!

Keep in mind that all of the rtlwifi family of drivers actually use the routines
in rtlwifi, and either rtl_pci or rtl_usb. They employ a lot more code than is
found in their specific directory.

I will not be answering every question like this, but in this case look at
_rtl_pci_interrupt().
