- Use bus_{read,write}_*(9) instead of bus_space_{read,write}_*(9) etc
and take advantage of rman_get_rid(9) in order to save some softc
members.
- Provide and consume module dependency information for lebuffer(4).
Add front-ends for the 'lebuffer' variants found on some SBus cards.2007-01-20T12:53:30ZMarius Stroblmarius@FreeBSD.org2007-01-20T12:53:30Zurn:sha1:0222c134799baf365e08199cabfefb3cff962c7b
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.
