sys/dev/bfe if_bfe.c if_bfereg.h
Log:
Fix three more bugs in bfe:
- Fix bfe_encap so that it will pass the address of the mbuf back up to its
caller if/when it modifies it, as it does when doing a m_defrag on a mbuf
chain.
- Make sure to unload the dmamap for ALL fragments of a packet, not just the
first
- Use BUS_DMA_NOWAIT for all bus_dmamap_load calls so that the allocation of
the
map is not delayed - this driver is not set up to handle such delays.
- Reduce the number of RX and TX buffers bfe uses so that it does not use more
bounce buffers than busdma is willing to allow it to use
With these changes, the driver now works properly for a user with a 2GB
system,
and it also works on my system when the acceptable address range is lowered
to 128MB.
Previously, both of these setups would act up after a few minutes of activity.
