This is the fourth version of the high latency patches (stuff common for usb and sdio). Most of Kalles comments have been addressed, except the start_once patch which is identical to the previous version. I need to investigate more how this feature affects the case where the interface is brought up and down several times. The first two patches adds inline wrappers to the newly introduced htt ops. I think these patches could have been submitted separately (as PATCH and not RFC) but I decided to include them in this RFC series instead. Adding them separately would have reduced the size of the patchset somewhat, but since the rest of the patches are depending on the first two, I decided not to submit them separately. I have tested USB support and the performance is similar to previous versions. Below are the results from iperf with a WUSB6100M: 192.168.1.190: WUSB6100M 192.168.1.244: other computer Uplink test results (WUSB6100M -> other computer): # iperf-client.sh 192.168.1.244 /usr/bin/iperf ------------------------------------------------------------ Client connecting to 192.168.1.244, TCP port 1234 TCP window size: 85.0 KByte (default) ------------------------------------------------------------ [ 3] local 192.168.1.190 port 50524 connected with 192.168.1.244 port 1234 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.1 sec 10.8 MBytes 8.95 Mbits/sec The result is not so good (I expect more from an 11ac device), but hopefully it is configuration related.

I think they could be related to patch 16 (that removes the pending TX counter), but since I don't know how to configure the device to generate HTT_T2H_MSG_TYPE_TX_COMPL_IND's the sw flow control had to be disabled. Since I no longer have access to any SDIO hardware I have not been able to try the SDIO stuff, so it might be broken.
