* [RFT V2 05/13] brcmsmac: add debug info message providing phy and radio info

For debug purposes it is good to have the phy and radio information
available in the log. Only logged when driver is build when BRCMDBG
or BRCM_TRACING kconfig are set.

* [RFT V2 02/13] brcmsmac: change pa_gain for bcm4313 iPA
From: Arend van Spriel @ 2013-08-13 20:03 UTC (permalink / raw)

In-Reply-To: <1376424220-10765-1-git-send-email-arend@broadcom.com>
The function wlc_lcnphy_load_tx_gain_table() has a target PA
gain specified for the iPA variant of the bcm4313. This gain
value is reduced to avoid PA distortion. The if-statement is
removed because it was rather redundant in the first place.
Please not that this patch does not provide full iPA support.

The bcm4313 iPA BT-WLAN combo cards need to be initialized with
a different switch control table. This patch adds that table.

* [RFT V2 03/13] brcmsmac: use ARRAY_SIZE in phytbl_lcn.c
From: Arend van Spriel @ 2013-08-13 20:03 UTC (permalink / raw)

In-Reply-To: <1376424220-10765-1-git-send-email-arend@broadcom.com>
This patch converts all sizeof(x)/sizeof(x[0]) instances to
ARRAY_SIZE macro in phytbl_lcn.c. The patch was made using
spatch with ARRAY_SIZE.cocci (see [1]).

Rework the code path in lcnphy tbl_init() for switch control
table programming. This also takes the iPA BT-combo card into
account.

That should be the same driver as the one I am using.
First, what chip is in your computer. Please send me the output of the command
'/sbin/lspci -nnv'. Only the stanza for the RTL8188CE will be needed. There are
at least 4 different chips that work with driver rtl8192ce.
Second, what is the make/model of the access point that you are using? Is the
firmware up to date?
Third, what is the encryption method you are using, and what is the maximum rate
for the connection? That will tell me if you are using 802.11g or 802.11n.

No.
There is only one driver for the RTL8723AE, thus it is not a surprise that the
one on the Realtek site behaves the same as the one in the kernel. Similarly,
the distros usually do not change the kernel, at least not for the device
drivers. Thus all of them should behave the same. In fact, if I learned that
some distro was applying a patch that was not in the mainline kernel, I would
refuse to support any user of that distro.
How are you measuring the signal strength? This device does not report an actual
strength - the driver manipulates the reported number into what "could" be a
signal strength in dBm.
Why is your device name "wlp3s0", rather than the usual "wlanX"? What is
controlling your connection. If it is wicd, note that I do not support that
piece of software. I use NetworkManager.
In my standard setup, iwconfig shows about -60 dBm for my device, and the
netperf results for 3 second intervals are as follows:
Pass 1
TCP_MAERTS Test: 8.76 9.21 8.37 7.84 8.75 10.61 14.11 9.24 9.95 10.00
RX Results: max 14.11, min 7.84. Mean 9.68(1.67)
TCP_STREAM Test: 8.61 9.84 3.94 3.39 4.90 4.79 4.01 5.89 6.13 9.38
TX Results: max 9.84, min 3.39. Mean 6.09(2.25)
Pass 2
TCP_MAERTS Test: 11.65 12.30 11.35 6.18 7.48 11.89 8.57 8.17 8.53 9.98
RX Results: max 12.30, min 6.18. Mean 9.61(2.01)
TCP_STREAM Test: 5.92 9.42 5.39 5.47 5.00 7.19 8.81 6.70 9.81 2.97
TX Results: max 9.81, min 2.97. Mean 6.67(2.06)
This is not the best performance that I have seen - this is an 802.11n AP
capable of 150 Mbps for these 1x1 devices.

The keymiss events are valid only in the last descriptor

* [PATCH 05/14] ath9k: Fix TSF processing
From: Sujith Manoharan @ 2013-08-14 3:41 UTC (permalink / raw)
To: John Linville; +Cc: linux-wireless
In-Reply-To: <1376451682-25862-1-git-send-email-sujith@msujith.org>
From: Sujith Manoharan <c_manoha@qca.qualcomm.com>
There is no need to calculate the mactime for chained
descriptor packets, so make sure that this is done
only for the last fragment of valid packets.
Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com>
