Module Name:    src
Committed By:   bouyer
Date:           Wed Mar 30 18:11:37 UTC 2011

Modified Files:
        src/sys/dev/pci: if_jme.c

Log Message:
Some bus_dma(9)-related and memory allocation fixes:
- always bus_dmamap_unload() before recycling a receive descriptor
- make sure to not sleep from interrupt context: call bus_dmamap_load with
  M_NOWAIT, and create dma maps BUS_DMA_ALLOCNOW.
- if a receive descriptor has a NULL mbuf try to allocate a new one, don't
  try to receive it.
