the problems it tickled by working outside the biglock on archs

the softnet taskq.

MULTIPROCESSOR, and quote the alpha ARM to explain why; while there, make the

call, instead of &curproc. The copy routine may sleep and we may resume on
a different processor. This has been plaguing the alpha MULTIPROCESSOR kernels
since the very beginning; it's amazing this did not cause more havoc.

after kernel bss but before end of the image, the page tables used
the read-only mapping of the hole. When booting a small non-generic
kernel, this resulted in a crash, while writing to the page tables
later.
Make sure that the page tables are created after esym and after
end.

Most of the ARP layer already take an ifp pointer and this makes clear
wich chunks of code are messing with ac_enaddr.
Note that our Ethernet code assume that these pointer are interchangeable
since the first element of the "struct arpcom" is a "struct ifnet".

Move bridge_input() outside of ether_input() in order to duplicate packets
flowing through a bridge port before applying any transformation on mbufs.
This saves a various m_adj(9)/M_PREPEND(9) dances and remove the bridge(4)
hack from vlan(4).

done by introducining a magic offset. Pages below this offset are mapped
with default memory attributes. Above this offset pages are mapped write
combining.

Do rule counter increments after state has been successfully
installed. This has an additional benefit of making error
handling a bit simpler.

Frame lengths are just input values and no driver mess with them.

There's not bit to indicate the speed of a USB3.0 device attached to a hub
port so do not abuse the PORT_TEST bit. Instead make the xhci(4) root hub
report the PORT_POWER_SS bit when appropriate and use it to determin the
speed of a new device.
While here make the root hub report the link state and config error, from
FreeBSD.

Pass the length to free(9), do not violate the radix/route layer and
set the gateway of a route a bit later to simplify error code path.

specify an address constraint even when free pages that meet the constraint
are still available. This happens because the old code was using the root
of the size tree as a starting point for a search down the address tree.
This meant only part of the address tree was searched, and that part could
very well not contain any of the pages that met the constraint. Instead,
always walk the address tree from its root if the list of single pages is
empty and the root of the size tree doesn't meet our constraints.

Most of the WiFi/Ethernet USB adapter only have one configuration and always
use its first interface. In order to improve USB descriptors parsing start
by reducing the number of places where a configuration is set.

comment about the emulation code requiring kernel text to be readable from

Add a few DIAGNOSTIC checks for rogue ptes passed to rmpage().
Make sure the pte extent operations and update_pcbs() run at >= IPL_SCHED.

receiving interface in the packet header of every mbuf.
The interface pointer should now be retrieved when necessary with
if_get(). If a NULL pointer is returned by if_get(), the interface
has probably been destroy/removed and the mbuf should be freed.
Such mechanism will simplify garbage collection of mbufs and limit
problems with dangling ifp pointers.
Tested by jmatthew@ and krw@, discussed with many.

When a bus is explored, do not probe the ports which status hasn't
changed. This saves a lot of I/O when attaching/detaching devices
and might help with some timing related problems.

This reduces differences between non-isoch and isoch transfers submissions,
makes the generic DMA buffer overrun check work with isoch transfers and
will allow some code simplifications in HC drivers.
Since short-transfers were never checked for isoch transfers, we now need to
pass the USBD_SHORT_XFER_OK flag to not change this behavior. This might be
revisited later.
