Detailed Description

struct il_ac_qos – QOS timing params for C_QOS_PARAM One for each of 4 EDCA access categories in struct il_qosparam_cmd

: Contention win, start value in numbers of slots. Should be a power-of-2, minus 1. Device's default is 0x0f. : Contention win, max value in numbers of slots. Should be a power-of-2, minus 1. Device's default is 0x3f. : Number of slots in Arbitration Interframe Space (before performing random backoff timing prior to Tx). Device default 1. : Length of Tx opportunity, in uSecs. Device default is 0.

Device will automatically increase contention win by (2*CW) + 1 for each transmission retry. Device uses cw_max as a bit mask, ANDed with new CW value, to cap the CW value.
