[ovs-dev] [PATCH v2 1/2] ovs-save: Save igmp flows in ofp_parse syntax

[Salvatore Daniele]

match.c generates the keyword "igmp", which is not supported in ofp-parse.
This means that flow dumps containing 'igmp' can not be restored.

Removing the 'igmp' keyword entirely could break existing scripts in stable
branches, so this patch creates a workaround within ovs-save by converting any
instances of "igmp" within $bridge.flows.dump into "ip, nw_proto=2".
