Hmm. I wonder what would happen if you connect A and
B's TX pairs and
C's RX pair together, and similarly for B/C TX and A RX, and C/A TX and
B RX.
As you wrote, nothing useful. You can connect one Tx pair to several Rx
pairs. I don't know how many, I've only ever tried connecting one extra
Rx pair. I don't know about connecting two or more Tx pairs together,
though. You'd end up with collisions, undetected by the transmitters,
and I don't know if 10baseT transmitters can handle that. Anyway, what
you're suggesting would connect all the Tx pairs together (A to B, then
B to C).
