bug: when creating an EPL, table 2 on NoviFlow pipeline resulted in `BadMatchCode.OFPBMC_BAD_WILDCARDS` #43

Closed viniarck closed 8 months ago

viniarck commented 10 months ago

This flow resulted in BadMatchCode.OFPBMC_BAD_WILDCARDS. It's a pipeline configuration issue, so the application is pushing what was described on EP031, but the pipeline on NoviFlow configuration wasn't supporting it, so this is a bug/reminder to make sure that the augmented EP031 will specify a new table, or network engineers will also change the config of table 2 to be flexible enough (which was what the spec was assuming so far), so this is a reminder to augment or review that part.
