This bit will control all transmit TX frame always delay 1 bit on enabled, but It'll transmit TX frame randomly delay 1 bit on disabled.
We had tested it with BurnInTest to check the performance, It'll not make the performance regression. So we'll directly add it on all baud rate.
Thanks -- With Best Regards, Peter Hong
