Re: XGMII New ElectricalI Characteristics
Hi Bob,
One of the decision on the clause is to end receiving frame when there is a
non-error control data on RXD between /S/ and /T/. Can you give more
details on the background of this decision? Of course this is rare, and
something
is very wrong when it happens. Or it could be timing problems on the RXC
inputs. As long the MAC can recover to receive next packet, it should be fine.
But ending the receiving process in this condition creates runt packets and
management won't have the right info. of the failure. If we can treat it like
we
seeing an /E/, of course it will a different error condition. And keeping
receiving
the frame until seeing /E/ or /I/ column. Host can always drop this frame
becasue
of the error condition, and it will have more info about what is wrong.
I think that other conditions that can end a receiving frame is /T/ and /I/
column.
Thanks,
Louis Lin
