Re: A Question about "Inter Packet Gap and SOP Lane alignment"


You're absolutely correct about the format of a XAUI or the 8B/10B PCS
column containing a /T/. Specifically, that the general format of this
EOP column is: TKKK, DTKK, DDTK or DDDT. However, my point was that the
/T/ and EOP is only ever used to terminate an Ethernet packet and is
completely independent of LSS. I was afraid that Sanjeev Mahalawat was
implying with his question that an EOP must follow an LSS message. It
should be clear that this is not the case.

Best Regards,
