FLOW-MOD-TABLE-FULL

[DFritzsche]

Can we please have more detailed cofmsg_error messages than the standard FLOW-MOD-TABLE-FULL. (and the table I use is not full)

[msune]

OpenFlow does not capture all the possible issues that can occur in a SW datapath (e.g. out-of-memory conditions).

It should be first checked which is the root cause of the failure during insertion (out of memory? validation? any other issue?), and if there is a more appropriate error code use it. Please provide more info.

Failure occurs due to the group ID not existing, likely. Then the error message is incorrect and should be fixed with OFPET_BAD_ACTION or OFPET_BAD_INSTRUCTION

[DFritzsche]

Can confirm that the group ID does not exist.

The group is not created because of eGroupModChainingUnsupported. Then, when I refer t that group it throws FLOW-MOD-TABLE-FULL.
