6008862bc2 Change callers of mtx_init() to pass in an appropriate lock type name. In
most cases NULL is passed, but in some cases such as network driver locks
(which use the MTX_NETWORK_LOCK macro) and UMA zone locks, a name is used.

645ed1a78b Fix a bug in the ste_setmulti() routine. The NIC has 4 16-bit multicast
hash registers, not 2 32-bit ones. This would prevent the multicasr filter
from being programmed correctly in some cases.

75ff968cd5 Apply patch supplied by Jonathan Chen: use the correct arguments to

of PCIM_CMD_PORTEN/PCIM_CMD_MEMEN.

07f65363cd Big round of minor updates:
- Use pci_get_powerstate()/pci_set_powerstate() in all the other drivers
  that need them so we don't have to fiddle with the PCI power management
  registers directly.
- Use pci_enable_busmaster()/pci_enable_io() to turn on busmastering and
  PIO/memory mapped accesses.
- Add support to the RealTek driver for the D-Link DFE-530TX+ which has
  a RealTek 8139 with its own PCI ID. (Submitted by Jason Wright)
- Have the SiS 900/National DP83815 driver be sure to disable PME
  mode in sis_reset(). This apparently fixes a problem on some
  motherboards where the DP83815 chip fails to receive packets.

08812b3925 Implement MTX_RECURSE flag for mtx_init().
All calls to mtx_init() for mutexes that recurse must now include
the MTX_RECURSE bit in the flag argument variable. This change is in
preparation for an upcoming (further) mutex API cleanup.
The witness code will call panic() if a lock is found to recurse but
the MTX_RECURSE bit was not set during the lock's initialization.

The old MTX_RECURSE "state" bit (in mtx_lock) has been renamed to
MTX_RECURSED, which is more appropriate given its meaning.

The following locks have been made "recursive," thus far:
eventhandler, Giant, callout, sched_lock, possibly some others declared
in the architecture-specific code, all of the network card driver locks
in pci/, as well as some other locks in dev/ stuff that I've found to
be recursive.

21b8ebd926 Make all Ethernet drivers attach using ether_ifattach() and detach using
ether_ifdetach().

The former consolidates the operations of if_attach(), ng_ether_attach(),
and bpfattach(). The latter consolidates the corresponding detach operations.

2e2de7f23f Move code to handle BPF and bridging for incoming Ethernet packets out
of the individual drivers and into the common routine ether_input().
Also, remove the (incomplete) hack for matching ethernet headers
in the ip_fw code.

The good news: net result of 1016 lines removed, and this should make
bridging now work with *all* Ethernet drivers.

The bad news: it's nearly impossible to test every driver, especially
for bridging, and I was unable to get much testing help on the mailing
lists.

95a1645553 Depend on miibus.
Note that if_aue doesn't strictly depend on usb because it uses the
method interface for calls rather than using internal symbols, and
because it's a child driver of usb and therefore will not try and do
anything unless the parent usb code is loaded at some point.  if_aue does
strictly depend on miibus as it will fail to link if it is missing.

a2c195896a Spruce up the Sundance ST201 driver:
- Convert to using TX descritor polling similar to the xl driver (the
  ST201 is a clone of the 3c90xB chipset and offers the same transmit
  polling scheme). This should reduce TX overhad a little.

- Make sure to reset PHY when switching mode, as in the starfire driver.

- Fix instances of free() that should be contigfree().

- Remove dead code.

98a229f65e As suggested by phk, unconditionalize BPF support in these drivers. Since
there are stubs compiled into the kernel if BPF support is not enabled,
there aren't any problems with unresolved symbols. The modules in /modules
are compiled with BPF support enabled anyway, so the most this will do is
bloat GENERIC a little.

9e4c647c74 Tweak these for what I hope is the last time: change the DRIVER_MODULE()
declaration for the interface driver from "foo" to "if_foo" but leave the
declaration for the miibus attached to the interface driver alone. This
lets the internal module name be "if_foo" while still allowing the miibus
instances to attach to "foo."

This should allow ifconfig to autoload driver modules again without
breaking the miibus attach.

0355003f26 Un-do the changes to the DRIVER_MODULE() declarations in these drivers.
This whole idea isn't going to work until somebody makes the bus/kld
code smarter. The idea here is to change the module's internal name
from "foo" to "if_foo" so that ifconfig can tell a network driver from
a non-network one. However doing this doesn't work correctly no matter
how you slice it. For everything to work, you have to change the name
in both the driver_t struct and the DRIVER_MODULE() declaration. The
problems are:

- If you change the name in both places, then the kernel thinks that
  the device's name is now "if_foo", so you get things like:

if_foo0: <FOO ethernet> irq foo at device foo on pcifoo
if_foo0: Ethernet address: foo:foo:foo:foo:foo:foo

  This is bogus. Now the device name doesn't agree with the logical
  interface name. There's no reason for this, and it violates the
  principle of least astonishment.

- If you leave the name in the driver_t struct as "foo" and only
  change the names in the DRIVER_MODULE() declaration to "if_foo" then
  attaching drivers to child devices doesn't work because the names don't
  agree. This breaks miibus: drivers that need to have miibuses and PHY
  drivers attached never get them.

In other words: damned if you do, damned if you don't.

This needs to be thought through some more. Since the drivers that
use miibus are broken, I have to change these all back in order to
make them work again. Yes this will stop ifconfig from being able
to demand load driver modules. On the whole, I'd rather have that
than having the drivers not work at all.

3de9d6fbe4 Don't restrict our requests for contiguous memory to addresses >= 1MB.
This fixes, at least, panics in ncr_attach() on i386's with about 5MB
of memory.  The restriction was a hack to leave some low memory for ISA
DMA, but on i386's we now allocate pages from the top down, so all the
restriction did was cause our allocations to fail when there is no free
memory above 1MB.

23e4757cd7 This commit adds device driver support for the Sundance Technologies ST201
PCI fast ethernet controller. Currently, the only card I know that uses
this chip is the D-Link DFE-550TX. (Don't ask me where to buy these: the
only cards I have are samples sent to me by D-Link.)

This driver is the first to make use of the miibus code once I'm sure
it all works together nicely, I'll start converting the other drivers.

The Sundance chip is a clone of the 3Com 3c90x Etherlink XL design
only with its own register layout. Support is provided for ifmedia,
hardware multicast filtering, bridging and promiscuous mode.
