To support large MTU, one or several separate channels must be allocated to calculate the TCP/UDP checksum separately, since the mac lacks enough buffers to hold a whole packet while it's being calculated. Furthermore, it seems that a single function channel is not quite enough to feed one of the 10Gig links, so allocate two channels for XAUI interfaces.
