+# Egress and Ingress Bandwidth Control
+The RTL8372/3 allows to control the bandwidth of data transmitted (egress) and/or
+admitted (ingress) at any given port. Once admitted, packets are internally switched
+at wire-speed, since the backplane of the devices has a bandwidth of 60GBit/s.
+
+The devices schedules transmission of packets by assigning packets to 8 queues
+implemented in hardware per port, which share a total of 8Mbit of memory internal
+to the switching part of the SoCs. Packets are assigned to the respective queues
+based on the priority assigned to a packet, which can be based on various
+properties of a packet such as  IEEE 802.1P priority, DSCP value, physical port
+number, destination or source MAC, Ether-Type-based, CVID, SVID, IPv4 source or
+destination IP, IPv4/IPv6 TOS field, IPv6 Flow Label and even TCP/UDP
+source/destination port. Once in a queue, packets are scheduled for egress
+based on differnent configurable algorithms.
+
+RTLPlayground currently allows only to control the bandwidth at ingress at a port
+or just before packets leave a port. There is no control of the priority assignment
+or queue scheduling mechanisms. The bandwidth can be controlled in steps of 16Kbit/s
+from 16Kbit/s to 10Gbp/s.
+
+The bandwidth control as currently implemented allows e.g. to assign a certain
+share of bandwidth to an attached device (e.g. to share an uplink), or simulate
+connections with low bandwidth and even bad connectivity with packet drops when
+ingress is not controlled by Flow Control but by simply droping packets.
+
+## Ingress/Egress control
+The relevant registers for controlling Ingress and Egress at a port are:
+```
+#define RTL837X_IGBW_CTRL		0x4c10
+#define IGBW_INC_BYPASS_PKT		0x100
+#define IGBW_INC_IFG			0x80
+#define IGBW_ADM_DHCP			0x20
+#define IGBW_ADM_ARPREQ			0x10
+#define IGBW_ADM_RMA			0x08
+#define IGBW_ADM_BPDU			0x04
+#define IGBW_ADM_RTKPKT			0x02
+#define IGBW_ADM_IGMP			0x01
+#define RTL837X_IGBW_PORT_CTRL		0x4C18

+#define RTL837X_EGBW_CTRL		0x447c
+#define EGBW_INC_IFG			0x02
+#define EGBW_CPUMODE			0x01
+```
+`RTL837X_IGBW_CTRL/RTL837X_EGBW_CTRL` control the behaviour of the bandwidth control
+at ingress and egress. The flags such as `IGBW_ADM_DHCP`control whether certain types
+of packets such as DHCP are exempt from being ingress controlled. The
+`IGBW_INC_IFG/EGBW_INC_IFG` flags control whether the Inter Frame Gaps are part of
+the bandwidth being controlled. `EGBW_CPUMODE` controls whether packets generated
+by the internal CPU are subject to egress control.
+
+`RTL837X_IGBW_PORT_CTRL/RTL837X_EGBW_PORT_CTRL` configure the bandwidth for ingress
+and egress at a port.
+
+`RTL837X_IGBW_PORT_FC_CTRL` configures whether packets are bandwidth-controlled using
+Flow Control (port-bit set), or simply dropped (port-bit clear).
+
+## Ingress/Egress bandwidth API
+The code currently provides the following functions:
+```
+void bandwidth_setup(void) __banked;
+void bandwidth_ingress_set(uint8_t port, __xdata uint32_t bw) __banked;
+void bandwidth_ingress_disable(uint8_t port) __banked;
+void bandwidth_ingress_drop(uint8_t port) __banked;
+void bandwidth_egress_set(uint8_t port, __xdata uint32_t bw) __banked;
+void bandwidth_egress_disable(uint8_t port) __banked;
+void bandwidth_status(uint8_t port) __banked;
+```c
+
+`bandwidth_setup()` is called at boot-time and configures excluding all special packets
+that may be for the CPU and packets outgoing from the CPU to be excluded from bandwidth
+control. IFG is not part of the bandwidth calculation.
+
+`bandwidth_ingress_set()` enables ingress bandwidth control for a particular port given
+the specified bandwidth. This also enabled Flow Control at a port.
+
+`bandwidth_ingress_set()` enables egress bandwidth control for a particular port given
+the specified bandwidth
+
+`bandwidth_ingress_disable() / bandwidth_egress_disable()` disable ingress and egress
+bandwidth control at a given port
+
+`bandwidth_ingress_drop(port)` configures packets exceeding bandwidth limitations to
+simply be dropped
+
+`bandwidth_status(port)` shows the current bandwidth control status for a given port
+
+## Bandwidth control configuration on the Serial Console
+The following commands are provided on the serial console:
+```
+> bw [in|out|status] <port> [<hexvalue>|off|drop]
+  Configures or shows the status of bandwidth control
+```
+The bandwidth is given as the `<hexvalue>` in Kbit/s. Note that the control is only
+possible at a granularity of 16 Kbit/s and the minimum value is also 16 Kbit/s. The
+hexadecimal numbers must be given in full bytes, i.e. have an even number of digits.
+
+To enable bandwidth control of ingress for physical port 2 to be set to 256 Kbit/s
+do:
+```
+> bw in 2 0100 
+```
+
+To drop packets when the bandwidth is exceeeded at port 2 do:
+```
+> bw in 2 drop 
+```
+
+To disable bandwidth control for incoming packets on port 2 do:
+```
+> bw in 2 off
+```
+
+## Bandwidth configuration via the Web Interface
+Not implemented, yet!
+
+## A Test using iperf3
+The following is and example how to test bandwidth control with a signle Linux device using
+network namespaces to route packets between a client and a server on the same Linux device
+through an external switch.
+
+You will need 2 network intefaces on the linux device, say, 2 USB-Ethernet controllers called
+eth0 and eth1: 
+```
+$ sudo ip netns add client
+$ sudo ip netns add server
+
+$ sudo ip link set dev eth0 netns client
+$ sudo ip link set dev eth1 netns server
+
+$ sudo ip netns exec client ip link set dev eth0 up
+$ sudo ip netns exec server ip link set dev eth1 up
+
+$ sudo ip netns exec client ip addr add dev eth0 192.168.99.1/24
+$ sudo ip netns exec server ip addr add dev eth1 192.168.99.2/24
+
+$ sudo ip netns exec server iperf3 -s
+```
+This will start an iper3 server in the above shell.
+
+In a different shell you can now run the iperf3 client against your server:
+```
+$ sudo ip netns exec client iperf -c 192.168.99.2
+```
+The LEDs on your switch where your network adapters are connected should start to flicker.
+On a 1GBit connection, you should see:
+```
+$ sudo ip netns exec client iperf3 -c 192.168.99.2
+Connecting to host 192.168.99.2, port 5201

+
+Now, we limit ingress on port 1 (connected to eth0) to 4 MBit/s:

+Which shows a large number of retries due to dropped packets and an average number

+back to the client by the server) of 210 KBit/s, the number is higher for the transmitted
+packets, because they may include dropped packets.

+Following is documentation for unmanaged switch marked as `Hi-K0402WS`.
+
+Original software is running UART on 9600 baud rate. 
+
+Using SPI clamp in-board is the only method for initial installation.
+
+The board has two flash chips `BY25Q16BS` with 16M-bit size. The front switch, switches between the two flash chips.
+These can be programed independently by using said switch - so it is e.g. possible to run the original and new firmware in parallel.

+## Power supply
+
+Input power is delivered via barell plug, `12V 1A` adapter was provided.
+Board has two supply rails. `0.95` and `3.3` volt.
+
+### `0.95` Core Voltage
+
+Voltage is made by a `Techcode TD1720` .
+
+### `3.3` Voltage
+
+Voltage is created by chip marked as `Techcode TD1720`.

+# TrendNet TEG-S562
+
+Following is documentation for unmanaged switch marked as `TEG-S563/EU H/W: V1.0R`.
+
+Original software is running UART on 57600 baud rate. The software does not allow to
+do anything fancy via serial. There is `IP` configuration which can be printed as well.
+There might be also some flash upload procedure, but using SPI clamp in-board seems to
+be easier method.
+
+The memory chip is `Winbond W25Q16JV` with 16M-bit size.
+
+## What does work
+
+1. 2.5G ports on all advertised speeds.
+2. SFP+ communication.
+3. Serial, Web UI.
+
+## Known issues
+
+1. LEDs are not initialized properly.
+
+## PCB

+Manufacturer information be found [on the product page](https://www.trendnet.com/support/support-detail.asp?prod=105_TEG-S562).

+## Power supply
+
+Input power is delivered via barell plug, `12V 1A` adapter was provided.
+Board has two supply rails. `0.95` and `3.3` volt.
+
+### `0.95` Core Voltage
+
+Voltage is made by a `APW8713` (U3).
+
+### `3.3` Voltage
+
+Voltage is crated regulated by chip marke as `GoIAT` (U2).
+
+## SFP SPI
+
+There is separate clock and data lines for both SFP modules. MSDA/MSCK 0 and 1 need to be enabled.
+
+SFP1 slot is connected to SPI0. SFP2 slot is connected to SPI1.
