From 0f2ed58e6e185bb7f22a534d12b755b7459177ef Mon Sep 17 00:00:00 2001 From: Alexander Bondar Date: Tue, 2 Jul 2013 19:51:09 +0300 Subject: [PATCH] iwlwifi: mvm: Change AM->PSM timeout for EAPOL frames Currently after sending EAPOL frame FW transition to power saving mode within 10 or 100 msec (as specified by power table command). According to new requirement this timeout for a specific EAPOL frame must be controlled by the driver by setting tx_pm_timeout field of TX_CMD to 2 (PM_FRAME_ENUM_MGMT). This value corresponds to 32 msec timeout.
