| Subject: | IPFIX options templates encoded incorrectly |
Patch attached.
Given the following example option template definition
{
SetId => 3,
TemplateId => 302,
FieldCount => 5,
ScopeCount => 3,
Template => [
{ Length => 4, Id => 130 }, # exporterIPv4Address
{ Length => 4, Id => 42 }, # exportedFlowRecordTotalCount
{ Length => 4, Id => 41 }, # exportedMessageTotalCount
{ Length => 4, Id => 8 }, # sourceIPv4Address
{ Length => 4, Id => 2 }, # packetDeltaCount
],
}
The FieldCount should be packed in the PDU as 5 not 2 (5 - 3)
