Improve ipfix template packet rewrite construction
Instead of repeatedly cutting, pasting, and hacking to create a new
callback, use vnet_flow_rewrite_generic_callback(). Add three
arguments to the flow rewrite callback:
(in) pointer to an array of report elements,
(in) length of array,
(out) pointer to the stream index
Change existing code prototypes. Code owners encouraged to evaluate
whether they can use the generic callback or not, at leisure.
/* ipfix field definitions for a particular report */
typedef struct
{
u32 info_element;
u32 size;
} ipfix_report_element_t;
Best generated like so:
_(sourceIPv4Address, 4) \
_(destinationIPv4Address, 4) \
_(sourceTransportPort, 2) \
_(destinationTransportPort, 2) \
_(protocolIdentifier, 1) \
_(flowStartMicroseconds, 8) \
_(flowEndMicroseconds, 8)

foreach_simple_report_ipfix_element
};

/* Set up the ipfix report */
memset (&a, 0, sizeof (a));
a.is_add = 1 /* to enable the report */ ;

/* Create the report */
