Fixed Function Stat TDI API support to retrieve stats/info (#90)
Browse files Browse the repository at this point in the history 
Added following to support fixed function stat/info retrieval.

01. added new class "class FixedFunctionStateTable" and create object
    of this type when table_type is "FixedFunctionState".
02. added back-end port manager handler APIs to retrieve info/stat info.
03. renamed existing fixed function manager APIS to meaningful name.

README file for PORT configuration with fixed function tdi/context JSON files.

Addition of PORT json files in bf_switchd config file
=======================================================
The bf_switchd configuration file should have a fixed function section.
This fixed function section can be used to enable fixed function TDI functionality
like port managers.

An example for bf_switchd configuration files can be found in port_mgr section
"fixed_function.conf".

Following example can be considered to enable PORT related functionality.

Example
=========

"fixed_functions" : [
{
"name": "port",
"tdi": "share/tdi_port.json",
"ctx": "share/tdi_port_ctx.json"
}
],


bf_switchd Commands to run the program:
====================================================================================

tdi_python
tdi.fixed.port.port

Rule to Create TAP port
=======================
add(DEV_PORT=0, PORT_TYPE="tap", PORT_DIR="default", PORT_IN_ID=0, PORT_OUT_ID =0, PIPE_IN="pipe", PIPE_OUT="pipe", MEMPOOL="MEMPOOL0", PORT_NAME="TAP0", MTU=1500)
add(DEV_PORT=1, PORT_TYPE="tap", PORT_DIR="default", PORT_IN_ID=1, PORT_OUT_ID =1, PIPE_IN="pipe", PIPE_OUT="pipe", MEMPOOL="MEMPOOL0", PORT_NAME="TAP1", MTU=1500)
add(DEV_PORT=2, PORT_TYPE="tap", PORT_DIR="default", PORT_IN_ID=2, PORT_OUT_ID =2, PIPE_IN="pipe", PIPE_OUT="pipe", MEMPOOL="MEMPOOL0", PORT_NAME="TAP2", MTU=1500)
add(DEV_PORT=3, PORT_TYPE="tap", PORT_DIR="default", PORT_IN_ID=3, PORT_OUT_ID =3, PIPE_IN="pipe", PIPE_OUT="pipe", MEMPOOL="MEMPOOL0", PORT_NAME="TAP3", MTU=1500)

Verify creation of TAP ports on host with command "ip a".

Statistics ouput for TAP port "2"
==================================
# enable pipeline before retrieving stats
tdi.fixed.port.enable

# TAP PORT "2" stats output

tdi.fixed.port> tdi.fixed.port.port_stat.get(DEV_PORT=2)
