+# mwlwifi
+mac80211 driver for the Marvell 88W8x64 802.11ac chip
+
+## Building mwlwifi With OpenWrt/LEDE
+1. Modify `package/kernel/mwlwifi/Makefile`:
+ ```
+ PKG_VERSION:=10.3.0.17-20160601
+ PKG_SOURCE_VERSION:=4bb95ba1aeccce506a95499b49b9b844ecfae8a1
+ ```
+
+2. Rename `package/kernel/mwlwifi/patches` to `package/kernel/mwlwifi/patches.tmp`.
+3. Run the following commands:
+ ```sh
+ make package/kernel/mwlwifi/clean
+ make V=s (-jx)
+ ```
+
+### Special Considerations
+* After driver 10.3.0.17-20160603, [MAX-MPDU-7991] should be removed from vht_capab command of hostapd.
+
+* Hostpad must include the following commit for 160 MHz operation:
+ ```
+ commit 03a72eacda5d9a1837a74387081596a0d5466ec1
+ Author: Jouni Malinen <jouni@qca.qualcomm.com>
+ Date: Thu Dec 17 18:39:19 2015 +0200
+
+ VHT: Add an interoperability workaround for 80+80 and 160 MHz channels
+
+ Number of deployed 80 MHz capable VHT stations that do not support 80+80
+ and 160 MHz bandwidths seem to misbehave when trying to connect to an AP
+ that advertises 80+80 or 160 MHz channel bandwidth in the VHT Operation
+ element. To avoid such issues with deployed devices, modify the design
+ based on newly proposed IEEE 802.11 standard changes.
+
+ This allows poorly implemented VHT 80 MHz stations to connect with the
+ AP in 80 MHz mode. 80+80 and 160 MHz capable stations need to support
+ the new workaround mechanism to allow full bandwidth to be used.
+ However, there are more or less no impacted station with 80+80/160
+ capability deployed.
+
+ Signed-off-by: Jouni Malinen jouni@qca.qualcomm.com
+
+ Note: After hostapd package 2016-06-15, this commit is already included.
+ ```
+
+* In order to let STA mode to support 160 MHz operation, mac80211 package should be 2016-10-08 or later.
+
+* WiFi device does not use HT rates when using TKIP as the encryption cipher. If you want to have good performance, please use AES only.
+
+* DTS parameters for mwlwifi driver (pcie@X,0):
+ ```sh
+ #Disable 2g band
+ marvell,2ghz = <0>;
+
+ #Disable 5g band
+ marvell,5ghz = <0>;
+
+ #Specify antenna number, default is 4x4. For WRT1200AC, you must set these values to 2x2.
+ marvell,chainmask = <4 4>;
+
+ #Specify external power table. If your device needs external power table, you must provide the power table via this parameter, otherwise the Tx power will be pretty low.
+ marvell,powertable
+ ```
+
+ To see if your device needs/accepts an external power table or not, run the following:
+ ```sh
+ cat /sys/kernel/debug/ieee80211/phy0/mwlwifi/info
+ ```
+
+ You should see a line in the results which looks like the following:
+ ```sh
+ power table loaded from dts: no
+ ```
+
+ If it is "no", it does not allow you to load external power table (for newer devices due to FCC regulations). If it is "yes", you must provide power table in DTS file (for older devices).
+
+* Changing interrupt to different CPU cores:
+ ```sh
+ #Use CPU0:
+ echo 1 > /proc/irq/irq number of phy0 or phy1/smp_affinity
+
+ #Use CPU1:
+ echo 2 > /proc/irq/irq number of phy0 or phy1/smp_affinity
+ ```
+
+* Note for DFS of WRT3200ACM (88W8964):
+
+ All WRT3200ACM devices are programmed with device power table. Mwlwifi driver will base on region code to set country code for your device and it will not allow you to change country code. There are another wifi (phy2) on WRT3200ACM which is not mwlwifi. It will allow you to change country code. Under this case, country code setting will be conflicted and it will let DFS can't work.
+
+ There are two ways to resolve this problem:
+ * Please don't change country code and let mwlwifi set it for you.
+ * Remove phy2. Under this case, even though you change country code, mwlwifi will reject it. Because phy2 is not existed, country code setting won't be conflicted. To do this, run the following commands (for OpenWrt/LEDE):
+
+ ```sh
+ opkg remove kmod-mwifiex-sdio
+ opkg remove mwifiex-sdio-firmware
+ reboot
+ ```
+
+ The better way is let mwlwifi set country code for you.
+
+## Replacing mwlwifi on a Current OpenWrt/LEDE Build
+
+1. Establish a symbolic link to your working mwlwifi directory with current mwlwifi package name under directory "dl":
+ ```sh
+ ls -l mwlwifi*
+ ```
+
+ You should see something like the following:
+ ```sh
+ lrwxrwxrwx 1 dlin dlin 48 mwlwifi-10.3.2.0-20170110 -> /home/dlin/home2/projects/github/mwlwifi
+
+ -rw-r--r-- 1 dlin dlin 4175136 mwlwifi-10.3.2.0-20170110.tar.xz
+ ```
+
+2. Back up original mwlwifi package and tar your working mwlwifi to replace original mwlwifi package:
+
+ ```sh
+ tar Jcvf mwlwifi-10.3.2.0-20170110.tar.xz mwlwifi-10.3.2.0-20170110/.
+ ```
+
+3. You can use `make V=s` to build the whole image or `make V=s package/kernel/mwlwifi/compile` to build mwlwifi package. The generated whole image or mwlwifi package can be found under directory "bin".
+
+Due to package version being the same as previous one, you need to add option `--force-reinstall` when you use `opkg` to update mwlwifi package on your device.
+
+## Monitor interface for debug
+
+1. Create moinitor interface mon0:
+ ```sh
+ iw wlan0/wlan1 interface add mon0 type monitor
+ ifconfig mon0 up
+ ```
+
+2. Use tcpdump to dump dhcp packets:
+ ```sh
+ tcpdump -vvvi mon0 -n port 67 and port 68
+ ```
+
+3. Use tcpdump to dump icmp packets:
+ ```sh
+ tcpdump -vvvi mon0 icmp
+ ```

+ * indicated. Currently only a single, fixed size Rx Pool is envisioned.
+ *
+ * Fmt0 is used for Slow path, when some processing of dot11 headers may still
+ * be required, or for promiscuous mode captures. It is in the HW RxINFO
+ * (rx_info_t) format including dot11_t followed by Payload. The Length field in
+ * the dot11_t is updated to only include Payload bytes, and is in Little Endian
+ * format. If the frame is too big, it is truncated to the buffer size, and
+ * promiscuous packets may also be configured for truncation to reduce load. The
+ * mark field is replaced with software status, and the RSSI will be updated to
+ * apply Rx calibration.
+ *
+ * Fmt1 is used for fast path Data packets in the run state, where all rx
+ * processing of dot11 headers is performed from radio FW. It has an AMSDU
+ * centric format of DA/SA/Len followed by SNAP, with the Length in Big Endian
+ * Format. In most cases conversion to Ethernet format is accomplished by
+ * copying 12 bytes to drop 8 bytes in the middle.
+ *
+ * Fmt2 is used for fast path AMSDU packets that are malformed. They just
+ * contain the dot11 header (dot11_t) containing the residual Len (Little
+ * Endian) after any valid MSDU have been extracted. The header is followed by
+ * the first invalid MSDU which will be truncated to 64 bytes.

+
+ VHT: Add an interoperability workaround for 80+80 and 160 MHz channels
+
+ Number of deployed 80 MHz capable VHT stations that do not support 80+80
+ and 160 MHz bandwidths seem to misbehave when trying to connect to an AP
+ that advertises 80+80 or 160 MHz channel bandwidth in the VHT Operation
+ element. To avoid such issues with deployed devices, modify the design
+ based on newly proposed IEEE 802.11 standard changes.
+
+ This allows poorly implemented VHT 80 MHz stations to connect with the
+ AP in 80 MHz mode. 80+80 and 160 MHz capable stations need to support
+ the new workaround mechanism to allow full bandwidth to be used.
+ However, there are more or less no impacted station with 80+80/160
+ capability deployed.
