This hardware is not present on any modern systems. The driver is quite
hackish (raw inb/outb instead of bus_space, and raw inb/outb to random

The wl(4) driver supports pre-802.11 PCCard wireless adapters that
are slower than 802.11b. They do not work with any of the 802.11
framework and the driver hasn't been reported to actually work in a
long time.
Relnotes: yes
The si(4) driver supported multiport serial adapters for ISA, EISA, and
PCI buses. This driver does not use bus_space, instead it depends on
direct use of the pointer returned by rman_get_virtual(). It is also
still locked by Giant and calls for patch testing to convert it to use
bus_space were unanswered.
Relnotes: yes
Currently boot parameters (r0 - r3) are forgotten in ARM trampoline code.
This patch save them at startup and restore them before jumping into kernel
_start() routine.
This is usefull when booting with Linux ABI and/or custom bootloader.

Now that we've switched over to using the vDSO on CloudABI, it becomes a
lot easier for us to phase out old features. System call numbering is no
longer something that's part of the ABI. It's fully based on names. As
long as the numbering used by the kernel and the vDSO is consistent
(which it always is), it's all right.
Let's put this to the test by removing a system call (thread_tcb_set())
that's already unused for quite some time now, but was only left intact
to serve as a placeholder. Sync in the new system call table that uses
alphabetic sorting of system calls.

- Read interrupt properties at bus enumeration time and store
it into global mapping table.
- At bus_activate_resource() time, given mapping entry is resolved and
connected to real interrupt source. A copy of mapping entry is attached
to given resource.
- At bus_setup_intr() time, mapping entry stored in resource is used
for delivery of requested interrupt configuration.
- For MSI/MSIX interrupts, mapping entry is created within
pci_alloc_msi()/pci_alloc_msix() call.
- For legacy PCI interrupts, mapping entry must be created within
pcib_route_interrupt() by pcib driver itself.

For almost every packet that is transmitted through ip_output(),
a call to in_broadcast() was made to decide if the destination
IP was a broadcast address. in_broadcast() iterates over the
ifnet's address to find a source IP matching the subnet of the
destination IP, and then checks if the IP is a broadcast in that
subnet.
This is completely redundant as we have already performed the
route lookup, so the source IP is already known. Just use that
address to directly check whether the destination IP is a
broadcast address or not.

axge_setmulti()/axge_setpromisc() with axge_rxfilter().
Multicast filter programming and promiscuous mode requires
access to a common RX configuration register so there is no need to
use separate functions with added complexity. axge_rxfilter() does
not read back AXGE_RCR register since accessing a register in USB
is too slow and we already have all knowledge of required
configuration. Rebuilding RX filter configuration is simpler and
faster than manipulating every bits after reading back the
register.
Note, axge_rxfilter() does not set RCR_IPE(IP header alignment on
32bit boundary) to disable extra padding bytes insertion. The
extra padding wastes ethernet to USB host bandwidth as well as
complicating RX handling logic. Current USB framework requires
copying RX frames to mbufs so there is no need to worry about
alignment. Previously axge_rx_frame() performed wrong bound check
due to the extra padding and it was broken when RX checksum
offloading is disabled. See added comment in axge_rx_frame () for
actual RX packet layout.
In axge_init(), disable WOL. It's meaningless to enable WOL in
normal operation.
In axge_rxeof(), use properly sized mbuf rather than blindly
allocating a mbuf cluster.
Use RX H/W checksum offloading only when administrator requested RX
checksum offloading. Previously it always used RX H/W checksum
offloading result regardless of RX checksum offloading state.
Separate L4 checksum offloading validation from L3 one and properly
set required offloading bits for each layer. This is to fix setting
L4 checksum offloading bits for L3 packets.
There are still lots of RX errors(probably RX FIFO overflows) under
moderate load. Users are strongly recommended to enable ethernet
flow control.

Remove useless ZLP padding which seems to come from Linux. Required

Micro-optimize updating IFCOUNTER_OPACKETS counter by moving it out

upper stack computes checksum while H/W checksum offloading is

Since loader itself is using 64MB memory for heap, updated zfsboot to
use same, and this also allows to support zfs large blocks.
Note, adding additional features does increate zfsboot code, therefore
this update does increase zfsboot code to 128k, also I have ported gptldr.S
update to zfsldr.S to support 64k+ code.
With this update, boot1.efi has almost reached the current limit of the size
set for it, so one of the future patches for boot1.efi will need to
increase the limit.
Currently known missing zfs features in boot loader are edonr and gzip support.
