src/sys/dev/pci/ixgbe: ix_txrx.c
Log Message:
Call bus_dmamap_unload(9) via ixgbe_dmamap_unload(), before freeing
DMA buffer. Also, when the buffer is already freed, do not call
bus_dmamap_unload(9) (no resource leaks with this change).
Otherwise, MMU fault occurs for some bus_dma(9) implementations.
With this fix, X550-T1 and X540-T1 work fine on alpha (at least
DS10 with PCI-PCIe reverse bridge).
Discussed with msaitoh. Thanks!
