freebsd_network: ether_input needs to support multiple packets.

It does on FreeBSD, though not many drivers make use
of this functionality (on Haiku, only iflib appeared to,
and it has a workaround at the moment.)

freebsd_network: Remove unneeded frees of if_l2com.

After 458c40fb2787fde1b9363cb43d15941591a7b923, if_l2com is not
allocated anymore, but I missed deleting these at that time.

freebsd_network: Adaptations in preparation for the OpenBSD layer.

Most of these changes however add things that FreeBSD has (with a few
exceptions noted in comments) which the OpenBSD shim layer merely needs
to make use of.

(FreeBSD used to have support for IFF_NEEDSGIANT but removed it. The
support instated here is very similar to what FreeBSD used to have.)

freebsd_network: Fix SIOCSIFMTU handling in ether_ioctl.

We cannot set anything below ETHERMIN nor greater than ETHERMTU here,
because we do not know what capabilities the driver actually has.
(The driver will have already caught and handled this ioctl if it
supports something more than the required minimum.)

freebsd_network: Drop arpcom from if_arp.h.

It was dropped from FreeBSD somewhere between 9 and 13.
OpenBSD has an equivalent structure but it is not compatible.
Best to avoid it altogether.

compat/freebsd_network: Catch BSD socket ioctl and act on within stack

freebsd_network: Add new APIs used by FreeBSD 13 drivers.

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.

Sync atheros813x with FreeBSD

Signed-off-by: Adrien Destugues <pulkomandy@pulkomandy.tk>

Fixes #12328.
Fixed a style error (2 lines between functions).

Actually put a note about the Haiku specific there, so that this isn't
overlooked accidentally on future updates.

Unlike FreeBSD we use a ifmultiaddr struct field to store the address and let
the ifma_addr point to that. Therefore freeing it caused a misaligned free and
then a double free, resulting in heap corruption for the next user to fall
victim to. Only happened when removing multicast addresses though.

merged changes from 8.2 FreeBSD release for most wlan drivers and net80211.
updated several firmwares for iprowifi4965 and iprowifi3945. Tested on iprowifi4965 only.

* Removing comments, that were leftovers from FreeBSD. These comments lead to
wrong impression about innerworkings of Haiku's compat layer.
* Use C++ comment style where appropriate.
* Whitespace cleanup.

The wlan part uses a very specific way to update multicast addresses for the
parent interface. It calls if_addmulti() on it but temporarily sets the ioctl
hook to NULL. We need to account for that so we don't crash on multicast setup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34699 a95241bf-73f2-0310-859d-f6bbb57e9c96

Remove the wlan specific headers to allow a clearer distinction between
ethernet and wlan drivers when compiling them. Also this removes the burden to
recompile every ethernet driver just because of changes in the wlan part.

Added new methods introduced in freebsd head that encapsulate macros to allow better binary compatibility if the locking way ever changes. These are not really useful, but needed for newer drivers sourcecode.

the gDeviceNameList[] entries are no longer in the same order.
* This fixes bug #3124.

* compat_open() still needs to get the stack module, as the callout
functionality needs it.
* callout_init_mtx() now initializes the timer manually, since the stack
might not have been loaded yet (since a device is now attached in
init_driver()).
* Minor other fixes; the FreeBSD compatibility layer should now be functional
again.
* Accidently put pci.c into the repository, but that was never meant to happen.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23026 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 :-)

The compatibility layer was calling if_init() too early, I've now moved it to the compat_open()
function.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23014 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!

* Calmed down the FreeBSD compatibility layer considerably.
* Now also sets the arpcom's ac_ifp field for completeness.
