mux c8f1495d8b Fix a bunch of bugs I came accross when looking at the ixgb(4) driver,
some of which are rather serious:
- Use the device sysctl tree instead of rolling our own.
- Don't create a bus_dmamap_t to pass to bus_dmamem_alloc(), it is
  bus_dmamem_alloc() that creates it itself.  The DMA map created
  by the driver was overwritten and its memory was leaked.
- Fix resource handling bugs in the error path of ixgb_dma_alloc().
- Don't use vtophys() to get the base address of the TX and RX rings
  when busdma already gave us the correct address to use!
- Remove now useless includes and the alpha_XXX_dmamap() hack.
- Don't initialize if_output to ether_output(), ether_ifattach() does
  it for us already.
- Add proper module dependencies on ether and pci.

Unfortunately, I'm not lucky enough to own an ixgb(4) card, nor a
machine with a bus where to plug it in and I couldn't find anyone able
to test these patches, so they are only build-tested and I won't MFC
them for 5.4-RELEASE.
