2014-03-17wil6210: use GROVladimir Kondratiev2-8/+8
GRO is easy to enable when already using NAPI framework, and it improves CPU utilisation. Enable it by default. Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-03-17wil6210: serialize fw_recovery and start_apVladimir Kondratiev2-4/+13

2014-03-17wil6210: fix secondary connectVladimir Kondratiev1-0/+4

2014-03-17wil6210: fw error recoveryVladimir Kondratiev4-1/+58
upon fw error interrupt - in STA mode, disconnect/cancel scan and then reset FW/HW added module param - no_fw_recovery which is false by default Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-03-17wil6210: Fix kernel oops in reset flowVladimir Kondratiev3-4/+21
wil_reset() removes vring's At the same time NAPI may be active performing Rx/Tx completion. If this happens, Rx/Tx polling functions going to access already removed vrings Make sure NAPI is idle and won't be started prior to vring removal. For this, track NAPI enabled state Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-03-17wil6210: fix memory leak in the AP flowVladimir Kondratiev2-0/+7
When switching between STA and AP modes, memory allocated for Rx vring leaks This is because start_ap() allocates Rx vring but stop_ap() do not free it. Logically, Rx vring is not valid (HW can't use it anymore), so free it in reset() Also, check double init for Rx vring and bail out with -EINVAL Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2014-03-17wil6210: reset on power goodVladimir Kondratiev2-2/+8
Configure hardware to perform full reset on "power good". This mean, reset HW on system boot. This improves card stability. By default this is off. Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2014-03-17wil6210: update target reset to support new HWVladimir Kondratiev3-1/+34

2014-03-17wil6210: generalize tx desc mappingVladimir Kondratiev2-27/+33
Introduce enum to describe mapping type; allow 'none' in addition to 'single' and 'page'; this is preparation for GSO Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-03-17wil6210: add scatter-gather supportVladimir Kondratiev4-67/+115
When setting fragmented skb for Tx, assign skb to the last descriptor and set number of fragments in the 1-st one On Tx complete, HW sets "DU" bit in Tx descriptor only for the last descriptor; so search for it using number of fragments field. Middle descriptors may have "DU" bit not set by the hardware. Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2014-03-17wil6210: Block data till "data port open" reportedVladimir Kondratiev5-6/+38
When connection established, as reported by WMI_CONNECT_EVENTID, 4-way handshaking required for the secure connection is not done yet. It is indicated by another WMI event. Wait for it and only then allow data traffic. In case of non-secure connection, FW reports "data port open" immediately after connection.

2014-03-14ath9k_hw: set ANI firstep as absolute values instead of relativeFelix Fietkau1-36/+5
On older chips, the INI value differ in similar ways as cycpwr_thr1, so convert it to absolute values as well. Since the ANI algorithm is different here compared to the old implementation (fewer steps, controlled at a different point in time), it makes sense to use values similar to what would be applied for newer chips, just without relying on INI defaults.

2014-03-14ath9k_hw: set ANI cycpwr_thr1 as absolute values instead of relativeFelix Fietkau1-38/+6
The table was copied from the ANI implementation of AR9300. It assumes that the INI values contain a baseline value that is usable as reference from which to increase/decrease based on the noise immunity value. On older chips, the differences are bigger and especially AR5008/AR9001 are configured to much more sensitive values than what is useful. Improve ANI behavior by reverting to the absolute values used in the previous implementation (expressed as a simple formula instead of the old table).

2014-03-14ath9k_hw: remove ANI function restrictions for AP modeFelix Fietkau1-11/+0
