- If check for net,ethernet/usb,device compatible node fails, try to find
.../usb/hub/ethernet, where ... is bus path that can depend on actual HW.
net,ethernet/usb,device compatibity strings are FreeBSD custom invention
that is used only in RPi DTBs and since there is no other way to tie USB
device to FDT node we just do our best effort here to work with upstream
device tree

the TCP_RFC7413 kernel option. This change removes those few instructions
from the packet processing path.
While not strictly necessary, for the sake of consistency, I applied the
new IS_FASTOPEN macro to all places in the packet processing path that
used the (t_flags & TF_FASTOPEN) check.

As of r302092, pipe is a wrapper around pipe2 and the pipe syscall is no
longer used. It is included only with the COMPAT_FREEBSD10 kernel option.
Add the compat option to support upgrades from systems with an earlier

Keep resource state consistent with INTRNG state - if intr_activate_irq

This will allow to add slave drivers in the same fashion as for iicbus.
Also, allow other code to add a child device and set its 'addr' ivar.
The ivar can only be set if it's unset, it can not be changed.
That could be used, for example, by a platform driver that has
a precise description of the hardware and, thus, knows what drivers
can handle what slaves.
The slave auto-probing code is unsafe and broken because it uses
7-bit slave addresses. It's going to be removed.
Note: internally the driver uses address of zero as an unset address
while smbus_get_addr() returns it as -1 for compatibility reasons.
The address is expected to be unset only for children that do not
work with slaves like, for example, smb(4).

This should have been committed in r307093: resource allocation depends
on source of the device tree. upstream dts has extra interrupt that we can
ignore
If pass order is not specified devices are attached in the order they are
defined in dts. Some interrupt consumers may be defined before intc. Also
make sure intc interrupt-parent local_intc is attached before intc itself.
TCPCB, it checks (so->so_options & SO_ACCEPTCONN) to determine whether or
not the socket is a listening socket. However, this causes the code to
access a different cacheline. If we first check if the socket is in the
LISTEN state, we can avoid accessing so->so_options when processing packets
received for ESTABLISHED sessions.
If INVARIANTS is defined, the code still needs to access both variables to
check that so->so_options is consistent with the state.

to add actions that run when a TCP frame is sent or received on a TCP
session in the ESTABLISHED state. In the base tree, this functionality is
only used for the h_ertt module, which is used by the cc_cdg, cc_chd, cc_hd,
and cc_vegas congestion control modules.
Presently, we incur overhead to check for hooks each time a TCP frame is
sent or received on an ESTABLISHED TCP session.
This change adds a new compile-time option (TCP_HHOOK) to determine whether
to include the hhook(9) framework for TCP. To retain backwards
compatibility, I added the TCP_HHOOK option to every configuration file that
already defined "options INET". (Therefore, this patch introduces no
functional change. In order to see a functional difference, you need to
compile a custom kernel without the TCP_HHOOK option.) This change will
allow users to easily exclude this functionality from their kernel, should
they wish to do so.
Note that any users who use a custom kernel configuration and use one of the
congestion control modules listed above will need to add the TCP_HHOOK
option to their kernel configuration.
