[LEDE-DEV] ath10k ct ack timeout/coverage class

[Ben Greear]

There are some un-documented hacks using the ct_special debugfs file.

Very unlikely they are hooked into LEDE.

See this code in wmi.h:

/* CT firmware only, and only builds after June 26, 2015 */
struct wmi_pdev_set_special_cmd {
#define SET_SPECIAL_ID_ACK_CTS 0 /* set ack-cts-timeout register */
#define SET_SPECIAL_ID_SLOT    1 /* set slot-duration register */
#define SET_SPECIAL_ID_SIFS    2 /* set sifs-duration register */

and the set_special logic in debugfs.

Thanks,
Ben

I recently tried a link at 1.2 Kilometers, but only got <1Mbps throughput. Does anyone know if coverage class/ack timeout is implemented in the ath10k-ct driver+firmware? Thanks
