Log:
 It is becomming more common that iscsi vendors use iscsi-redirectors and redirect
 initiators to a different host/port and thus often redirect to non-3260.
 
 The heuristics to detect iscsi is quite weak since there is very little
 in the average iscsi header that can be used to semi-reliably identify
 something as iscsi and not random data/something else.
 As such, the heuristics also use/rely on the port being 3260 in order
 to reduce the otherwise massive numbver of false positives that would arise.
 
 
 Add decoding of the text key/value pairs and trigger on TargetAddress.
 This field would describe a address/port where we can quite reliably 
 assume that this traffic is indeed iscsi and not something else.
 
 
 When seeing the iscsi redirect/TargetAddress, use this as a signalling hint
 and register a conversation dissector for TCP to that address/port so that 
 any future packet to/from this port is sent to the iscsi dissector.
 
 
 If the signalling/redirect is not in the capture, wireshark will not detect
 the traffic as iscsi and the user will have to use DecodeAs.  and manually
 \set it to iscsi.
