0fcefb433d Update NetBSD Foundation copyrights to 2-clause BSD
The NetBSD Foundation states "Third parties are encouraged to change the
license on any files which have a 4-clause license contributed to the
NetBSD Foundation to a 2-clause license."

This change removes clauses 3 and 4 from copyright / license blocks that
list The NetBSD Foundation as the only copyright holder.

0e4e9e170c Use convenience functions where possible instead of accessing the PCI
configuration registers directly.

Remove pci_enable_io calls where they are redundant. The PCI bus driver
will set the right bits when the corresponding bus resource is activated.

Remove redundant pci_* function calls from suspend/resume methods. The
bus driver already saves and restores the PCI configuration.

c75c2a68a7 - Use bus_{read,write}_*(9) instead of bus_space_{read,write}_*(9) etc
and take advantage of rman_get_rid(9) in order to save some softc
  members.
- Provide and consume module dependency information for lebuffer(4).

ef544f6312 o break newbus api: add a new argument of type driver_filter_t to
bus_setup_intr()

o add an int return code to all fast handlers

o retire INTR_FAST/IH_FAST

0c7d35d0b9 Remove BUS_DMA_WAITOK from bus_dma_tag_create() invocations as it's
no valid flag there.

d2255d0286 Use bus_get_dma_tag() to obtain the parent DMA tag so le(4) works on
platforms requiring this.

3a225e0b62 Revert the part of rev. 1.3 which changed the software style to be
set to ILACC rather than PCnet-PCI as VMware doesn't implement ILACC
compatibility, resulting in the VMware virtual machine to crash if
enabled. Add a comment regarding usage of ILACC vs. PCnet-PCI mode.

60c430f511 - Revert if_le_pci.c rev. 1.2; although lnc(4) is now gone, le_pci_probe()
still should return BUS_PROBE_LOW_PRIORITY instead of BUS_PROBE_DEFAULT
  in order to give pcn(4) a chance to attach in case it probes after le(4).
- Rearrange the code related to RX interrupt handling so that ownership of
  RX descriptors is immediately returned to the NIC after we have copied
  the data of the hardware, allowing the NIC to already reuse the descriptor
  while we are processing the data in ifp->if_input(). This results in a
  small but measurable increase in RX throughput.
  As a side-effect, this moves the workaround for the LANCE revision C bug
  to am7900.c (still off by default as I doubt we will actually encounter
  such an old chip in a machine running FreeBSD) and the workaround for the
  bug in the VMware PCnet-PCI emulation to am79000.c, which is now also
  only compiled on i386 (resulting in a small increase in RX throughput on
  the other platforms).
- Change the RX interrupt handlers so that the descriptor error bits are
  only check once in case there was no error instead of twice (inspired
  by the NetBSD pcn(4), which additionally predicts the error branch as
  false).
- Fix the debugging output of the RX and TX interrupt handlers; while
  looping through the descriptors print info about the currently processed
  one instead of always the previously last used one; remove pointless
  printing of info about the RX descriptor bits after their values were
  reset.
- Create the DMA tags used to allocate the memory for the init block,
  descriptors and packet buffers with the alignment the respective NIC
  actually requires rather than using PAGE_SIZE unconditionally. This might
  as well fix the alignment of the memory as it seems we do not inherit
  the alignment constraint from the parent DMA tag.
- For the PCI variants double the number of RX descriptors and buffers
  from 8 to 16 as this minimizes the number of RX overflows im seeing with
  one NIC-mainboard combination. Nevertheless move reporting of overflows
  under debugging as they seem unavoidable with some crappy hardware.
- Set the software style of the PCI variants to ILACC rather than PCnet-PCI
  as the former is was am79000.c actually implements. Should not make a
  difference for this driver though.
- Fix the driver name part in the MODULE_DEPEND of the PCI front-end for
  ether.
- Use different device descriptions for PCnet-Home and PCnet-PCI.
- Fix some 0/NULL confusion in lance_get().
- Use bus_addr_t for sc_addr and bus_size_t for sc_memsize as these are
  more appropriate than u_long for these.
- Remove the unused LE_DRIVER_NAME macro.
- Add a comment describing why we are taking the LE_HTOLE* etc approach
  instead of using byteorder(9) functions directly.
- Improve some comments and fix some wording.

a7ee7a7d6a Add le(4), a driver for AMD Am7900 LANCE and Am79C9xx PCnet NICs ported
from NetBSD. This driver actually can replace lnc(4). Advantages over
lnc(4) are:
- Cleaner and more flexible regarding MD needs.
- Endian-clean and MPSAFE.
- Supports ALTQ, VLAN_MTU, ifmedia.
- Uses 32bit DMA for the PCI variants.

This commit includes front-ends for the dma(4) pseudo-bus found on SBus-
based sparc64 machines (thus supports the on-board LANCE in Sun Ultra 1)
and PCI. In order to actually replace lnc(4), the front-ends for ISA and
the PC98 CBUS would have to be added but for which I don't have hardware
to test.
