Added files:
sys/dev/le if_le_lebuffer.c lebuffer_sbus.c
Log:
Add front-ends for the 'lebuffer' variants found on some SBus cards.
These are shared-memory variants based on Am79C90-compatible chips
that apart from the missing DMA engine are similar to the 'ledma'
variant including using a (pseudo-)bus/device for the buffer that
the actual LANCE device hangs off from. The performance of these is
close to that of the 'ledma' one, like expected at a few times the
CPU load though.
