tsutsui 2f456b8f00 Make sure to initialize the all Rx descriptors properly in sonic_init()
even if mbuf for them are already allocated.
This fixes "receive descriptor exhausted" errors.

thorpej 623f83a793 Use BUS_DMA_READ and BUS_DMA_WRITE in some obvious places. 2001-07-19 16:25:23 +00:00
thorpej 5c0f65ea82 Do a little manual CSE, taking unneeded comparisons out of loops,
and shrinking the object code somewhat.  On an R4400:

thorpej b7ea2efc25 A new DP83932 ``SONIC'' driver, which uses bus_dma(9) and does I/O
directly to mbufs.  Handles both 32-bit and 16-bit, big- and little-
endian configurations of the chip (we could squeeze out some conditionals
yet, though).
