Ok.
1. Why do you use clocked from cable scheme of Rx, instantiating FIFO after
the Rx block? Why not to put dual-port FIFO right after MII? I think system
clock is much more accurate and predictable than cable-driven.
2. I have some consideration about collision prevention technique.
"Traditional" ethernet cores wait for a random time after a collision occured.
There's other algorithm: core starts transmit immediately after collision with
some probability (p), or waits traffic-adjustable time with (1-p) probability.
2nd algorithm increases brandwith of a network, although requires more gates
to be implemented.
3. For a new members, I think it'll be comfortable to read old mail archive
off-line. Please if it possible put all messages from an archive in 1
downloadable txt or html file.
