[PATCH] mac80211: Recalc min chandef when station is associated

2015-12-13 Thread Emmanuel Grumbach

From: Ilan Peer 

The minimum chandef bandwidth calculation was done only in case
a new station was inserted (or when an existing station was removed).
However, it is possible that stations are inserted before they are
associated, e.g., when FULL_AP_CLIENT_STATE is supported and user
space adds stations unassociated.

Fix this by calling ieee80211_recalc_min_chandef() whenever
a station transitions in/out the associated state, and only
consider station marked as associated.

[PATCH v2] mac80211: limit the A-MSDU Tx based on peer's capabilities

2015-12-13 Thread Emmanuel Grumbach

In VHT, the specification allows to limit the number of
MSDUs in an A-MSDU in the Extended Capabilities IE. There
is also a limitation on the byte size in the VHT IE.
In HT, the only limitation is on the byte size.
Parse the capabilities from the peer and make them
available to the driver.

In HT, there is another limitation when a BA agreement
is active: the byte size can't be greater than 4095.
This is not enforced here.

Obviously we forgot to update the other drivers. Please drop this

This is really weird. I don't see how that could be firmware related.
BTW, -10.ucode is fairly old :) we have -16.ucode out there.

[PATCH 07/12] staging: wilc1000: change join_req_drv type and it's name

2015-12-13 Thread Glen Lee

To use wilc_get_vif_idx instead of the last get_id_from_handler, join_req_drv
needs to be changed it's type with wilc_vif and name as well.
As a result, get_id_from_handler is not used anymore, so remove it.

[PATCH 06/12] staging: wilc1000: wilc_set_wfi_drv_handler: pass vif index

2015-12-13 Thread Glen Lee

Pass index of vif instead of hif_drv. wilc_get_vif_idx is used to get correct
index of vif.
In the handler function handle_set_wfi_drv_handler, use vif instead of hif_drv,
and use hif_drv_handler->handler instead of hif_drv when deinitialize wilc
device.

[PATCH 03/12] staging: wilc1000: take vif instead of drv in hostIFthread

2015-12-13 Thread Glen Lee

In the first patch, we sent vif to hostIFthread. we can use vif instead of
drv in the all functions which handle the commands from cfg operations.
Change first argument host_if_drv with wilc_vif and use hif_drv of wilc_vif.
Pass vif to the functions as well.
In case of timer callback functions, set vif to the data and use vif instead
of hif_drv.
Lastly, initialize u32RcvdAssocRespInfoLen since changing hif_drv with vif
causes one uninitialied build warning.
Now we have vif that currently being used so we can use interface index of
wilc_vif to send to wilc device.

[PATCH 02/12] staging: wilc1000: remove argument hif_drv

2015-12-13 Thread Glen Lee

In previous patch we add new argument vif which has hif_drv in it's member.
Therefore, no need to pass hif_drv in those functions. Remove argument
struct host_if_drv and use hif_drv of vif.

[PATCH 05/12] staging: wilc1000: use vif index to communicate with wilc device

2015-12-13 Thread Glen Lee

We now have vif index in all functions related with host interface thread.
wilc_get_vif_idx and wilc_get_vif_from_idx are added to get id and vif
respectively.
Relace get_id_from_handler with wilc_get_vif_idx and get_handler_from_id with
wilc_get_vif_from_idx. Remove unused function get_handler_from_id as well.
We get vif where wilc_get_vif_from_idx is called, so pass vif to msg.vif.

There are two get_id_from_handler left. They will be removed in later patch.

[PATCH 01/12] staging: wilc1000: pass vif to hostIFthread

2015-12-13 Thread Glen Lee

We will pass vif, which is currently being used as net_device, instead of
hif_dev. This is the first step to use index of vif to pass to the driver.
Add new argument vif to all the functions that send message to hostIFthread and
set vif to msg.vif. As a result, hostIfthread will get vif.
In later patch, we will remove drv of host_if_msg and use vif instead of it.

[PATCH 00/12] Use index of interface to communicate with wilc device

2015-12-13 Thread Glen Lee

Wilc device now use index of wfidrv_list which is list of host_if_drv pointers.
Each host_if_drv correspond with each wilc_vif interface, so we can use index
of vif. Therefore, so no need to make another list, wfidrv_list, to lookup
which interface the device is communicating.

Here are brief steps,
Firstly, Pass wilc_vif, currently being used, as msg argument to host interface
thread to use index of vif.
Secondly, Remove argument hif_drv since wilc_vif has it in it's member.
Thirdly, use index of vif to communicate with wilc device.
Lastly, remove unused structure and functions related with wfidrv_list
because it is not used anymore.

Last patch is bug fix which was found during patching this.

vif has wilc in it's members so no need to have wilc in host_if_drv.
It is redundant so just remove it and use wilc of vif.
