Why do the physical interfaces report (correctly) that they're negotiated at 1000Mb/s, but when I `cat /proc/net/bonding/bond0` I get 100Mbps for the member interfaces, and when I ` mii-tool bond0` I get 10Mbps for the bond?

Just one piece of the puzzle...
From mii-tool man page:
"This program is obsolete. Valid media are only 100baseT4, 100baseTx-FD,100baseTx-HD, 10baseT-FD and 10baseT-HD ethernet cards. For replacement check ethtool."
