cb60aeaf06 Don't base the number of jumbo segments on page size, instead base it on the

c70a5f4668 Incorporate the O_NONBLOCK open semantics of Linux and Solaris. This allows
an application to upon a tape (yea, even the non-control device) even if
it cannot establish a mount session. If the open cannot establish a mount
session and O_NONBLOCK was specified, the tape becomes 'open pending mount'.
All I/O operations that would require access to a tape thereafter until
a close attempt to initiate the mount session. If the mount session succeeds,
the tape driver transitions to full open state, else returns an appropriate
I/O error (ENXIO).

At the same time, add a change that remembers whether tape is being opened
read-only. If so, disallow 'write' operations like writing filemarks that
bypass the normal read-only filtering operations that happen in the write(2)
syscall.

c3a7d3e5b2 In ncp_sysctl_connstat(), the SLIST_FOREACH() logic to check 'error'
resulted in deadcode, as 'error' could never be 0.  What this logic
was originally meant to handle is not clear -- it's been this way
(broken) since at least RELENG_4.

dfb4dff72d Add code that clears certain capabilities from the member interface, these are
restored when its removed from the bridge.

At the moment we only clear IFCAP_TXCSUM. Since a locally generated packet on
the bridge may be sent out any one or more interfaces it cant be assumed that
every card does hardware csums. Most bridges don't generate a lot of traffic
themselves so turning off offloading won't hurt, bridged packets are
unaffected.

645eb22044 Add the following to the taskqueue api:
taskqueue_start_threads(struct taskqueue **, int count, int pri,
			const char *name, ...);

This allows the creation of 1 or more threads that will service a single
taskqueue.  Also rework the taskqueue_create() API to remove the API change
that was introduced a while back.  Creating a taskqueue doesn't rely on
the presence of a process structure, and the proc mechanics are much better
encapsulated in taskqueue_start_threads().  Also clean up the
taskqueue_terminate() and taskqueue_free() functions to safely drain
pending tasks and remove all associated threads.

The TASKQUEUE_DEFINE and TASKQUEUE_DEFINE_THREAD macros have been changed
to use the new API, but drivers compiled against the old definitions will
still work.  Thus, recompiling drivers is not a strict requirement.

567602e49b In spx_attach() and spx_detach(), there is no need to check whether the
ipxpcb is NULL or not: in attach it will be, and on detach it won't be.

faeb71daa6 1) move all link state detection code from bge_tick_locked() to bge_link_upd()
2) use more robust way of link state handling for BCM5700 rev.B2 chip
3) workaround bug of some BCM570x chips which cause spurious "link up" messages
4) fix bug: some BCM570x chips was unable to detect link state changes after
   ifconfig down/up sequence until any 'non-link related' interrupt generated.
   (this happened due to pending internal link state attention which blocked
   interrupt generation)

7f7a28fe5e * fix bst.status. We mark some bits, but forgot to reset all of them
before.  The symptom is that the battery inform us its charge and discharge
  at the same time...

* fix bst.rate to correctly output the (dis)charging rate.  We'll use
  the current average over one minute command and not the at_rate command.
  Note that this method is not correct if the capacity_mode is set, but
  since we don't set it ourself, it is not a problem.

  The at_rate do not give the actual rate but is used to compute the
  estimated time for (dis)charging a battery.  We should actually
  write an estimation of the actual rate using at_rate cmd and then
  perform a read to the various estimators.

a8f06e9570 In the splnet(9) times netgraph(4) was synchronous and if a message
had been replied, the reply was always delivered to the originator
synchronously.

With introduction of netgraph item callbacks and a wait channel with
mutex in ng_socket(4), we have fixed the problem with ngctl(8) returning
earlier than the command has been proceeded by target node. But still
ngctl(8) can return prior to the reply has arrived to its node.

To fix this:
 - Introduce a new flag for netgraph(4) messages - NGM_HASREPLY.
   This flag is or'ed with message like NGM_READONLY.
 - In netgraph userland library if we have sent a message with
   NGM_HASREPLY flag, then select(2) until reply comes.
 - Mark appropriate generic commands with NGM_HASREPLY flag,
   gathering them into one enum {}. Bump generic cookie.

402d4e2682 - The inline asm in this file uses output operands before all input
operands are consumed so use the appropriate constraint modifier.
  Before this change GCC used one register for both an input and an
  unrelated output operand of in_addword(), causing the input to be
  overwritten before it was consumed and thus breaking in_addword().
  For in_cksum_hdr() and in_pseudo() this change is more or less
  cosmetic.
