WebI realized that currently my PHY works in 100Mbp half-duplex mode, and that could eventually be a problem, when many packets arrive and the PHY tries to send some data in the same time (although the PHY should probably manage this). Actually, it is the MAC that has to handle half-duplex retransmission, not the PHY.
