One of us needs a pair of glasses ;-) I read ;
minimal specification for asymetric flow control
Has to do with flow control.
If you say a device to pause , process the buffers and

I never played with set port flowcontrol so I getting
impressed ....
I loved the old style no buffer , drop packet .
Things are really getting more complex is it not ?
