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.)

kernel/vm: Remove default kernel read/write flags

`fix_protection` will not apply `B_KERNEL_READ_AREA` and
`B_KERNEL_WRITE_AREA` by default.

Kernel drivers that directly call `create_area` or `create_area_etc`
and do not pass any protection flags have been updated to
apply `B_KERNEL_READ_AREA | B_KERNEL_WRITE_AREA` instead.

freebsd_network: PCI handling cleanup in preparation for USB support.

Should not have any functional change.

freebsd_network: Cleanup bustag handling.

* Add an enum with general BUS_SPACE_TAG values for use across platforms.
* Add proper entries for generic IRQs and MSIs and make use of them.

freebsd_network: Clean up and break PCI methods out of bus.cpp.

freebsd_network: Add pci_msix_table_bar().

Needed by the e1000 driver from FreeBSD 13. Tested in QEMU with e1000e.

compat/freebsd_network: Fix dead store

Fix value stored to 'newPowerManagementStatus' is never read.
Pointed out by Clang Static Analyzer.

It seems FreeBSD's pci_set_powerstate_method() writes 'status'
(newPowerManagementStatus in Haiku) with PCI_WRITE_CONFIG
(pci_write_config in Haiku).

freebsd_network: Define _KERNEL for C++ files too.

This also allows the removal of a function that is also in the cpufunc.h header.

freebsd_network: Handle 64 bit memory BARs.

This adds the upper 32 bits for address and size.

freebsd_network: Apply empty size and type check to IO ports.

Factor out the conversion to BAR index and hand the pci_info to both
memory and IO port allocation functions. Then apply the same checks
in the IO port case as are done for memory.

This aligns with what is done on FreeBSD.

freebsd_network: use proper BAR size in bus_alloc_mem_resource

This time we use the pci_info directly, it avoids a possible race with
PCI config regs, and we already have the value there anyway.

Signed-off-by: Augustin Cavalier <waddlesplash@gmail.com>
One crucial fix by me: check if size == 0. This avoids the deadlock
seen in #14795.

freebsd_network: Restore the hard-coded 128KB physical map size.

mmu_man changed this to be dynamically computed based on the BAR size.
It seems his computation was somehow incorrect, as it tries to allocate
a very large region here which deadlocks in the physical memory mapper.
Restoring this to 128KB un-breaks the new ipro1000 driver on more
recent hardware.

"Fixes" #14795.

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.

FreeBSD compability layer optimized read and writes.

FreeBSD has a simple inlined bus_space_read while Haikus had one
with call overhead.
This still needs cleanup as it is x86 specific, which it was already.
Also it redefines inX and outX defines as arch/x86/arch_cpu.h has a
C++ namespace so it can't be included from FreeBSD drivers C-files.

The results of these changes should be worth it though.

FreeBSD compat layer: fix typo ...

introduced in 656e05ec86375a592c360f7f4d2ea321e74cd8ff

FreeBSD compat layer: implement MSI-X support.

Update FreeBSD network drivers with the 9.1 release

Fixed up network stack and drivers for x86_64.

* Various compilation fixes.
* Fixes to the FreeBSD compatibility layer (from comparing the x86-
specific bits with the equivalent amd64 sources in FreeBSD).
* Compile all the Ethernet drivers except for sis900 and wb840, these
require a bit more work to fix (will file a ticket soon). Tested
ipro1000 and rtl81xx, no issues.

C++ified remaining C users of arch_cpu.h.
