Kind of a hijack of this thread, but now that you have your bonding
working, does /proc/net/bonding/bond0 show your slave interfaces linked
at their correct gigabit speeds, or at 100 Mbps?  I'm setting up a
couple of R815s and while 'ethtool eth0' shows it at 1000Mbps (and that
agrees with the switch port as well), /proc/net/bonding/bond0 shows all
slaves at 100Mbps.  Just wondering if I'm missing something or if that's
a bug somewhere.

It does appear that I'm getting gig speeds when doing some initial tests
with the bond0 interface.
