Hi all, I have been trying to work on rtwn(4) for a little more than a year and a half with very limited success. The device does not receive any interrupts whatsoever and thus Rx fails. (Exception: it seems to receive a null interrupt once every hour when idle). When I run "tcpdump -ni wlan0 -y IEEE802_11_RADIO", FreeBSD will execute rtwn_set_promisc(), but fail to receive anything. The device works on Linux, so this is not a hardware issue. I have exhausted my options and have literally no what what the problem is. My code is located here: https://github.com/khanzf/rtl8188ee Does anyone have any ideas what the failure may be? Specifically: A) Is my initialization code even correct? If not, where is it wrong? B) Why is the device not receiving Rx interrupts? Unless anyone can determine *exactly* where the issue lays, I will be very regrettably abandoning this project that I have spent a considerable amount of personal time one. Thanks and my apologies to send this upsetting email. -- Farhan Khan PGP Fingerprint: B28D 2726 E2BC A97E 3854 5ABE 9A9F 00BC D525 16EE
