Modified Files:
        src/sys/arch/sgimips/mace: if_mec.c

Log Message:
Improve mec(4)'s TX routine by reducing possible unnecessary mbuf copies
as much as possible before TX DMA.
With this new TX DMA buffer allocation strategy, most of TX packets are
sent without allocating new mbufs and copying data into them.

See the following mail for details:

No objection on port-sgimips.
