390ffae2b4 Fix tx ttag pcap filter capture filter syntax

d17ab7ab42 Use TtagTimeInterval to determine ttag markers 
This is for interlaved mode; sequential mode was already using it

3c0bc067fa Retain seq as param for sendQueueTransmit for now 
If and when we remove PacketSequence::ttagL4ChecksumOffset we will take a call
if we should revert back to passing seq->sendQueue instead of seq at that time

223e44a6e3 Run stream latency timers only when required 
Required => At least one port is tracking stream stats

Also changed some optimization FIXMEs as TODOs

6108de9b4f Remove comment about trying read-write lock 
The stream timingHash is read by getStreamStats() while it is read/write
for processRecords(), the latter is a more frequent operation so there's
no real benefit of using a read-write lock instead of simple mutex.

10befe0a66 Remove PcapTxTtagStats::handle_ member 
PcaptxTtagStats inherits from PcapSession which already includes a protected
handle_ member.

This removal was likely left off when PcapTxTtagStats started inheriting from
PcapSession.

4394c7ffee Rework sequential mode build for new ttag algo 
The previous commit changed the algo to determine which packets were Ttag'd,
but changes were done only for interleaved mode.

This commit adds the changes required for sequential mode.

ef1c166e7f Change algo to infer next Ttag pkt (interleaved mode) 
The algo works for the following cases of interleaved streams -
 * pktListDuration < ttagTimeInterval
 * pktListDuration > ttagTimeInterval
 * some streams have Ttag, some don't
    - first stream has Ttag
    - first stream does NOT have Ttag
 * no streams have Ttag

Changes for sequential mode are pending

f56ce2e2ec Add explicit packet set for interleaved streams 
Interleaved mode used an implicitly added packet set in both base and Turbo
code. This has been chaned to use an explicit mode to keep things consistent.

Turbo code still has the implicit packet set related code - that needs to be
removed, once the explicit packet set code is validated and tested.

f4c21e1ae4 Change StreamTiming::timing_ from QList to QHash 
Using QList meant we need to know the port count in the constructor - which is
difficult to know because StreamTiming is designed as a singleton

757d3f1b24 Add initial cut of StreamTiming class 
This singleton class will keep track of Ttag timing across all ports and GUIDs.

A bunch of FIXMEs/TODOs are pending for this class implementation; also this
class has not been hooked up to the rest of the code yet.

682d0cc5c9 Create a Tx Ttag tracker thread 
For now we are just debug printing timestamp with T-TagId and GUID. We
need to store this tuple and compare when we Rx the same - this will be
in a upcoming commit.

2104936b69 Don't create implicit packet sets for Tx 
As part of Turbo changes, we made changes to create explicit packet
sets, but for the base code we continued creating implicit packet
sets for some cases. With this change we don't create any implicit
packet set.

This change needs to be tested thoroughly for multiple cases.
