ipfix-export: refactor params to the callback fns
When a new flow-report is created the caller provides 2 callback functions. These functions both take a pointer to the exporter, plus a pointer to the source and dest address. However the pointers to the address are not adding any value as these are always set to the src/dest addresses of the exporter (which is already being passed). Remove these parameters and leave the callback functions to get the addresses out of the exporter. Type: improvement Signed-off-by: Paul Atkins <patkins@graphiant.com> Change-Id: I36dec394f30e85cdca120dd8706b5d90f5e07c48
