The SMD values are in the new draft which Ludwig has and should post very soon. They were supposed to be in the last draft – I haven’t figured out why they were missing. Framemaker crashed once and they may have gotten lost in the crash
and I didn’t notice. SMD-V 0x07 SMD-R 0x19 There was also a value correction in the table that I’m sure I’d already corrected but it wasn’t corrected in the preview draft.
SMD-S3 should be 0xB3, not 0x83. The values were in the tutorial slides. If you think some extra time should be added to the PFC reaction time when MAC Merge is implanted, then propose something in a comment. Regards, Pat From: Beaudoin, Denis [mailto:dbeaudoin@xxxxxx]
The reason I am asking is that we are trying to implement and associated coverage and IET impacts flow run out requirements and calculating those requirements has run into some issues. And since they are not
changed in the IET draft the base 802.3 values must work, which we are finding to not be true. There are a couple of other items we have run into as well in the newer draft. There is the SMD-R and SMD-V which are used in the state machines and they are not defined. Regards Denis Beaudoin DMTS Texas Instruments

Denis, Why you are asking this? In my mind the flow control is no more needed. At least the combination makes no sense for me from the standpoint of applications. There was a similar discussion during the joint .1TSN and .3br meeting with the conclusion that flow control can be substituted by this better approach of IET
combined with the different .1TSN approaches on top. Mit freundlichen Gruessen / With best regards,
