90cc51a1ab Don't iterate over the ifnet addr list in ip_output()
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.

db68f7839f Try to fix gcc compilation errors (which are right).
nat64_getlasthdr() returns an int, which can be -1 in case of error,
storing the result in an uint8_t and then comparing to < 0 is not
helpful.  Do what is done in the rest of the code and make proto an
int here as well.

a5d826557f Introduce axge_rxfilter() which configures RX filtering and replace
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.

7c10cf8c28 Switch to TX header format rather than directly manipulating header
structures.  This simplifies mbuf copy operation to USB buffers as
well as improving readability.  The controller supports Microsoft
LSOv1(aka TSO) but this change set does not include the support due
to copying overhead to USB buffers and large amount of memory waste.

Remove useless ZLP padding which seems to come from Linux.  Required
bits the code tried to set was not copied into USB buffer so it had
no effect.  Unlike Linux, FreeBSD USB stack automatically generates
ZLP so no explicit padding is required in driver.[1]

Micro-optimize updating IFCOUNTER_OPACKETS counter by moving it out
of TX loop since updating counter is not cheap operation as it did
long time ago and we already know how many number of packets were
queued after exiting the loop.

While here, fix a checksum offloading bug which will happen when
upper stack computes checksum while H/W checksum offloading is
active.  The controller should be notified to not recompute the
checksum in this case.

2c55d0903d Add SHA512, skein, large blocks support for loader zfs.
Updated sha512 from illumos.
Using skein from freebsd crypto tree.
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.

e15461c7e9 mips/broadcom: Implement CFE-based EARLY_PRINTF support.
This adds support for EARLY_PRINTF via the CFE console; the aim is to
provide a fix for the otherwise cyclic dependency between PMU discovery
and console printf/DELAY:

- We need to parse the bhnd(4) core table to determine the address (and
  type) of the PMU/PLL registers and calculate the CPU clock frequency.
- The core table parsing code will emit a printf() if a parse error is
  hit.
- Safely calling printf() without EARLY_PRINTF requires a working
  DELAY+cninit, which means we need the PMU.

Errors in core table parsing shouldn't happen, but lack of EARLY_PRINTF
makes debugging more difficult.

1680854946 Implement userspace gettimeofday(2) with HPET timecounter.
Right now, userspace (fast) gettimeofday(2) on x86 only works for
RDTSC.  For older machines, like Core2, where RDTSC is not C2/C3
invariant, and which fall to HPET hardware, this means that the call
has both the penalty of the syscall and of the uncached hw behind the
QPI or PCIe connection to the sought bridge.  Nothing can me done
against the access latency, but the syscall overhead can be removed.
System already provides mappable /dev/hpetX devices, which gives
straight access to the HPET registers page.

Add yet another algorithm to the x86 'vdso' timehands. Libc is updated
to handle both RDTSC and HPET.  For HPET, the index of the hpet device
to mmap is passed from kernel to userspace, index might be changed and
libc invalidates its mapping as needed.

Remove cpu_fill_vdso_timehands() KPI, instead require that
timecounters which can be used from userspace, to provide
tc_fill_vdso_timehands{,32}() methods.  Merge i386 and amd64
libc/<arch>/sys/__vdso_gettc.c into one source file in the new
libc/x86/sys location.  __vdso_gettc() internal interface is changed
to move timecounter algorithm detection into the MD code.

Measurements show that RDTSC even with the syscall overhead is faster
than userspace HPET access.  But still, userspace HPET is three-four
times faster than syscall HPET on several Core2 and SandyBridge
machines.

51c762d172 By default, allow all to read the HPET registers pages. At the same
time, by, by default disallow writes to the mmaped HPET pages.

Intent is to allow userspace to use HPET as fast (i.e. no-syscall)
timecounter for gettimeofday(2).  Unfortunately, the permission model
does not make it possible to safely unhide /dev/hpet in the jails even
if default mode is set to 0444, because untrusted jailed root may
change device permissions to writeable.
