RE: [RPRWG] More comments on preemption
A correction, Devendra. Ethernet does not re-transmit
on FCS error. IP does, after considerable ack/nack delay.
RPR, I presume, does not keep a packet around to re-transmit
on FCS error either.

Actually, this is what I thought when pre-emption was suggested first. By
creating a CRC error (Ethernet case), we essentially re-transmit the packet.
