1. Optimize LaunchTime Tx feature based on section 3.3.2.9.3.4 of doc#682924 rev-1.4.2 requirement. 2. Configurate Qbv scheduler to isolate the video traffic and others traffic. The cycle time of the scheduler is the frame cycle time of 50fps. According SMPTE 2110-21 standard, the video packets transmission will end at the 784us from the end of cycle. The queue 0 is for video packets transmission. The other queues is for others traffic. So, the queue 0 is opened during the whole cycle, and the other queues is opened at the 784us from the end of cycle. 3. Optimize time sync precision by adding clock freqency adjustment. 4. Fix remote ptp4l NOT receiving DELAY_REQ message while send PTP message over UDP.
To enable TSN pacing, "--pacing_way tsn" command line argurment is required.
Fix ptp not working on igc when master starts ptp4l with argument "-4" to broadcast ptp message over UDP.
Because the first few reading tx timestamp attempts always failed, we have set total 50 attempts to tolerate the fails. So, it is unnecessary to print error messages of the first few attempts. Error message is required only when the number of attempts is larger than 50

The phc2sys isn't enabled by default. To enable phc2sys, add command line arguement "--phc2sys".

Be considered as synchronized while the max delta is continuously below 300ns.

Synchronize PHC to system clock in nano seconds precision. To enable phc2sys, additional command line argument "--phc2sys" is required. The phc2sys feature is only available on Linux.
