freebsd_network: Break bus macros out into a separate header.

Now copied directly from FreeBSD.

Also change copyright info of the main file, as the remaining parts have
almost entirely been written by me at this point.

freebsd_network: Add child drivers directly rather than finding symbols.

This method is much less error-prone than the prior one, as that required
the driver structure to have an exported symbol identical to its "name"
field, a fact that is usually true but not always (we've had an ifdef
in the atheroswifi driver for a while now due to this.)

So when we have it, we now just use the driver_t* directly, which
should push any of these problems from the run-time stage to the
compile-time stage. It's also a significant performance
improvement.

freebsd_network: Lots of additions and modifications for iflib.

freebsd11_network -> freebsd_network.

FreeBSD 12 has no major changes to the ifnet KPIs that constitute a
source compatibility break, save a single one related to locking
which doesn't really apply to us, and so we don't need to create
a "freebsd12_network" directory to work through the upgrades.

bus_read_region_1: implement with bus_space_read_region_1

Update FreeBSD network drivers with the 9.1 release

Network drivers are updated from FreeBSD 9.0

* updated drivers are 3com, ar81xx, atheros813x, attansic_l1, attansic_l2,
broadcom440x, broadcom570x, dec21xxx, ipro100, ipro1000, jmicron2x0,
marvell_yukon, nforce, rtl8139, rtl81xx, syskonnect, via_rhine, vt612x

added some missing functions and definitions for FreeBSD 8.2


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42315 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Changed definition of driver_intr_t to the way it is defined in FreeBSD.
The internal_intr structure needed to be adapted accordingly, otherwise it
would not compile anymore.
This definition is needed by the aironet (if_an.c) driver I'm currently
porting.
* Extending FreeBSD compat layer a bit in preparation of porting the remaining
wlan drivers.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34620 a95241bf-73f2-0310-859d-f6bbb57e9c96

* reordering of headerfile inclusion to comply to FreeBSD 8
ordering.
this makes porting driver (especially wifi ones) more
convinient
* based on FreeBSD svn revision 196691

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33739 a95241bf-73f2-0310-859d-f6bbb57e9c96

Adding bus_barrier macro to compatibility layer.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26312 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented device_detach(), and bus_generic_detach() - both are needed by
the updated mii code on destruction.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23032 a95241bf-73f2-0310-859d-f6bbb57e9c96

Completely renovated the FreeBSD compatibility layer:
* Removed NETDEV() and DEVNET() macros and functionality.
* The exported devices are now attached to ifnet objects only, therefore, the
ifnet object now has the receive queue, and everything else a device could
need.
* There is now a root device where everything else is attached, it currently
only holds the pci_info structure, so it's more or less a PCI child.
* This simplified the device handling a bit everywhere.
* We now attach drivers already in init_driver() - this is needed as drivers
may publish more than one interface when being attached.
* Implemented device_delete_child(), device_attach() (which bus_generic_attach()
now uses), device_is_attached(), and device_is_alive().
* Therefore, if_initname() does now the actual job of registering the devices.
* On open, if_init() is called which comes pretty close to what our open()
is supposed to do.
* Updated ukphy.c to the one from FreeBSD 7 where used (we should probably
move that into the compat layer, anyway).
* The MII driver array must now be NULL terminated; therefore you don't need
to specify the count anymore.
* Moved PCI code from compat.c to bus.c.
* Moved the driver code from device.c to driver.c.
* Removed superfluous init_compat_layer() function.
* Fixed a few bugs, a few things weren't brought down correctly.
* The rtl8139 interrupt routine now checks if it really was the cause of the
interrupt - this code is not tested, either, it may not work (which would
then require a work-around like I did for the 3com driver).
* The HAIKU_PROTECT_INTR_REGISTER in the rtl8139 driver was pretty much useless
which is why I removed it.
* Probably introduced a lot of new bugs, though - I haven't tested this code
at all yet. It will probably just crash :-)


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23019 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Updated the FreeBSD compatibility layer for network drivers to FreeBSD 7
(RELENG_7_BP).
* There are many white spots, though, most notable PCI MSI(-X) support, and
jumbo frames.
* Fixed removing interrupts for the INTR_FAST case. Since FreeBSD 7 added
a new interrupt "filter" mechanism, we can finally report if the interface
was handled by a device or not (though only very few devices support this
yet).
* Updated the 3com, rtl8139, e1000, and via_rhine drivers to the latest code
base. They all compile, but I haven't tested them after the changes yet!
