internally, other than to set it when they gain their first address.
Every caller of mcstop() bar one was either preserving the state of IFF_UP
itself or was conditional on its already being clear, so the only effect of
this is to simplify the code and to change that one case, thereby curing
PR port-macppc/12088 (underflows on "mc" cause it to be taken down).
directly, call the function pointer (*if_input)(ifp, m). The input routine
expects the packet header to be at the head of the packet, and will adjust
as necessary. Privatize the layer 2 input and output routines, allowing
*_ifattach() to set them up as appropriate.
internal ethernet on the Quadra/Centris 660av/840av.
Add initial support for the PSC (DMA controller) to support the above
(DMA SCSI remains unsupported). This involved also changing the way
that several interrupts are handled.
Above from David Huang <khym@bga.com>
Since the interrupts changed somewhat, we must also make the ipls
dynamic, defaulting to their prior levels and adjusted for the AVs.
I modelled this on the hp300.
