+* IPQ806x DWMAC Ethernet controller
+
+The device inherits all the properties of the dwmac/stmmac devices
+described in the file net/stmmac.txt with the following changes.
+
+Required properties:
+
+- compatible: should be "qcom,ipq806x-gmac" along with "snps,dwmac"
+ and any applicable more detailed version number
+ described in net/stmmac.txt
+
+- qcom,nss-common: should contain a phandle to a syscon device mapping the
+ nss-common registers.
+
+- qcom,qsgmii-csr: should contain a phandle to a syscon device mapping the
+ qsgmii-csr registers.
+
+Example:
+
+ gmac: ethernet@37000000 {
+ device_type = "network";
+ compatible = "qcom,ipq806x-gmac";
+ reg = <0x37000000 0x200000>;
+ interrupts = <GIC_SPI 220 IRQ_TYPE_LEVEL_HIGH>;
+ interrupt-names = "macirq";
+
+ qcom,nss-common = <&nss_common>;
+ qcom,qsgmii-csr = <&qsgmii_csr>;
+
+ clocks = <&gcc GMAC_CORE1_CLK>;
+ clock-names = "stmmaceth";
+
+ resets = <&gcc GMAC_CORE1_RESET>;
+ reset-names = "stmmaceth";
+ };
The address family, socket addresses etc. are defined in the
include/net/af_ieee802154.h header or in the special header
-in our userspace package (see either linux-zigbee sourceforge download page
-or git tree at git://linux-zigbee.git.sourceforge.net/gitroot/linux-zigbee).
+in the userspace package (see either http://wpan.cakelab.org/ or the
+git tree at https://github.com/linux-wpan/wpan-tools).
One can use SOCK_RAW for passing raw data towards device xmit function. YMMV.
Those types of devices require different approach to be hooked into Linux kernel.
-MLME - MAC Level Management
-============================
-
-Most of IEEE 802.15.4 MLME interfaces are directly mapped on netlink commands.
-See the include/net/nl802154.h header. Our userspace tools package
-(see above) provides CLI configuration utility for radio interfaces and simple
-coordinator for IEEE 802.15.4 networks as an example users of MLME protocol.
-
-
HardMAC
=======
assoc_req, assoc_resp, disassoc_req, start_req, and scan_req are optional.
All other fields are required.
-We provide an example of simple HardMAC driver at drivers/ieee802154/fakehard.c
-
SoftMAC
=======
This layer is going to be extended soon.
-See header include/net/mac802154.h and several drivers in drivers/ieee802154/.
+See header include/net/mac802154.h and several drivers in

Device drivers API
Fake drivers
============
-In addition there are two drivers available which simulate real devices with
-HardMAC (fakehard) and SoftMAC (fakelb - IEEE 802.15.4 loopback driver)
-interfaces. This option provides possibility to test and debug stack without
-usage of real hardware.

6LoWPAN Linux implementation
============================
-The IEEE 802.15.4 standard specifies an MTU of 128 bytes, yielding about 80
+The IEEE 802.15.4 standard specifies an MTU of 127 bytes, yielding about 80
octets of actual MAC payload once security is turned on, on a wireless link
with a link throughput of 250 kbps or less. The 6LoWPAN adaptation format
[RFC4944] was specified to carry IPv6 datagrams over such constrained links,
It deprecates HC1 and HC2 compression and defines IPHC encoding format which is
used in this Linux implementation.
-All the code related to 6lowpan you may find in files: net/ieee802154/6lowpan.*
+All the code related to 6lowpan you may find in files: net/6lowpan/*
+and net/ieee802154/6lowpan/*
To setup 6lowpan interface you need (busybox release > 1.17.0):
1. Add IEEE802.15.4 interface and initialize PANid;
