Not "cached by the switch" else your rl driver would not have known
about it. The rl driver logged the "collision" because it started
sending a packet and was not able to copy it 100% in real time so it
concluded somebody else was transmitting at the same time.

If the card is configured in full duplex mode it should not be verifying
copy of its own data when sending, by definition. Unless there is some
sort of out-of-band communications between ethernet ports operating via
full duplex.

The human mind ordinarily operates at only ten percent of its
capacity -- the rest is overhead for the operating system.
