From de8af45520f47d14397b603beefae3d2983ce787 Mon Sep 17 00:00:00 2001 From: Bruno Randolf Date: Fri, 17 Sep 2010 11:37:12 +0900 Subject: ath5k: Simplify cw_min/max and AIFS configuration Get rid of overly complicated cw_min/max and AIFS configuration: * Validate values in ath5k_hw_set_tx_queueprops(), so we can use them directly without further checks or computation in ath5k_hw_reset_tx_queue(). * Simplifiy by using AR5K_TUNE_AIFS|CWMIN|CWMAX variables directly since we don't support XR or B channels. That way we can also remove AR5K_TXQ_USEDEFAULT and the confusing logic around it. * Update data types: AIFS is u8, CW's are u16. * Remove now unneeded variables in ath5k_hw.
