[VOL-4185] Reset OF connection on Core restart

This fix resets the OF connection between the OFAgent and
the OF controller when the connection between the Voltha Core and
OFAgent is down (Voltah Core restarts).  This allows ONOS to
prevent any actions done on Voltha including stats update.

Ofagent-go

Ofagent-go provides an OpenFlow management interface for Voltha. It is a rewrite in Golang of the original ofagent that was written in python / twisted. The main driver behind the work was to introduce true concurrency to the agent for performance/scalability reasons.

Building

  1. Outside $GOPATH

    1. Read-only git clone https://github.com/opencord/ofagent-go.git
    2. To Contribute git clone https://gerrit.opencord.org/ofagent-go

  2. Compile go build -mod=vendor -o ./build/ofagent-go

Running

  • Normal Logging
    • ./build/ofagent-go -ofaddress=localhost openflowPort=6653 -volthaAddress=localhost -volthaPort=50057
  • Debug Logging
    • ./build/ofagent-go -debug -ofaddress=localhost openflowPort=6653 -volthaAddress=localhost -volthaPort=50057

Building with a Local Copy of voltha-protos or voltha-lib-go

If you want to build/test using a local copy or voltha-protos or voltha-lib-go this can be accomplished by using the environment variables LOCAL_PROTOS and LOCAL_LIB_GO. These environment variables should be set to the filesystem path where the local source is located, e.g.

LOCAL\_PROTOS=$HOME/src/voltha-protos
LOCAL\_LIB\_GO=$HOME/src/voltha-lib-go

When these environment variables are set the vendored versions of these packages will be removed from the vendor directory and replaced by coping the files from the specified locations to the vendor directory. NOTE: this means that the files in the vendor directory are no longer what is in the git repository and it will take manual git intervention to put the original files back.
