  Log:
  Miscellaneous fixes:
  - Fix compilation without GEM_DEBUG.
  - Do not #define GEM_DEBUG by default; it adds overhead (due to bzero()ing
    RX space) and is not needed any more, since the driver is quite stable
    now.
  - Fix watchdog timeouts when failing to load TX packets.
  - Do not forcibly limit the number of descriptors used for a packet to
    GEM_NTXSEGS, by passing this number to bus_dma_tag_create(). There is
    no requirement for a limit any lower than the total number of
    available descriptors, and the present limit caused network problems
    due to mbuf chains requiring more descriptors.
    GEM_NTXSEGS is still used to estimate the interrupt window size, for
    which we just need an estimate.
