I've noticed this as well. In my case, the problem was
because the PHY was advertising and connecting full-duplex
and the CPM was doing half-duplex -- yet another problem due
to inadequate PHY communication.
Also, there is a problem with the 8260 CPM generating spurious
TX underrun errors and late collisions -- the driver does things
according to the spec, but there is an errata about this problem.
I'm about halfway through a fix for this. The problem only
seems to occur on 10 Mbit hubs.
