700cfba72d cxgbe(4): Overhaul the shared code that deals with the chip's TP block,
which is responsible for filtering and RSS.

Add the ability to use filters that match on PF/VF (aka "VNIC id") while
here.  This is mutually exclusive with filtering on outer VLAN tag with
Q-in-Q.

9610c89750 Fix a couple of silly mistakes in r291962.
- Handle the case where no DOF helper is provided. This occurs with the
  currently-unused DTRACEHIOC_ADD ioctl.
- Fix some checks that prevented the loading DOF in the (non-default)
  lazyload mode.

380344a7af Fix fasttrap tracepoint locking.
Upstream, tracepoints are protected by per-CPU mutexes. An unlinked
tracepoint may be freed once all the tracepoint mutexes have been acquired
and released - this is done in fasttrap_mod_barrier(). This mechanism was
not properly ported: in some places, the proc lock is used in place of a
tracepoint lock, and in others the locking is omitted entirely. This change
implements tracepoint locking with an rmlock, where the read lock is used
in fasttrap probe context. As a side effect, this fixes a recursion on the
proc lock when the raise action is used from a userland probe.

Code may still be executing from the wrappers at unload time and thus is
not generally safe to unload.  Converting the wrappers to use
EVENTHANDLER(9) will allow this to safely drain on active threads in

4f8a1fd8cd cxgbe(4): Updated register dumps.
- Get the list of registers to read during a regdump from the shared
  code instead of the OS specific code.  This follows a similar move
  internally.  The shared code includes the list for T6.

- Update cxgbetool to be able to decode T5 VF, T6, and T6 VF register
  dumps (and catch up with some updates to T4 and T5 register decode).

737d4f6c93 As reported on the transport@ and current@ mailing lists, the FreeBSD TCP
stack is not compliant with RFC 7323, which requires that TCP stacks send
a timestamp option on all packets (except, optionally, RSTs) after the
session is established.

This patch adds that support. It also adds a TCP signature option to the
packet, if appropriate.

20893a44b7 Since kernel modules can now contain sections of type SHT_AMD64_UNWIND,
the boot loader should not skip over these anymore while loading images.
Otherwise the kernel can still panic when it doesn't find the .eh_frame
section belonging to the .rela.eh_frame section.

Unfortunately this will require installing boot loaders from sys/boot
before attempting to boot with a new kernel.

adds a lock to ensure only a single device is accessing the hardware. A

This was extracted from a larger review to add OHCI support to the

f36aa2b792 Pass MNTK_NO_IOPF and MNTK_UNMAPPED_BUFS flags from the lower
filesystem to the nullfs mount.

MNTK_NO_IOPF must be present on the nullfs struct mount so that struct
file fo_read and fo_write fops operate in the mode requested by the
lower mount.

MNTK_UNMAPPED_BUFS allows VOP_GETPAGES() to use unmapped buffers.  It
does not matter for VOP_GETPAGES() calls from vm_fault() since handle
of the vm_object always points to the lower vnode.  But it may be
useful for other situations where VOP_GETPAGES() is used.

- Update the hardware debug sysctls (hidden within dev.<tNnex>.<n>.misc.*) to

21640df213 hyperv/hn: Add multiple channel support, a.k.a. vRSS
Each channel contains one RX ring and one TX ring.  And we
try to distribute the channels to different evenly.

Note: Currently we don't have enough information to extract
the RSS type and RSS hash value from the received packets.

This greatly improves the TX/RX performance for 8 virtual CPU
Hyper-V over 10Ge: it can max out 10Ge for TCP when multiple
RX/TX rings are enabled.

This almost doubles the TX/RX performance for locally connected
Hyper-Vs: was 6Gbps w/ 128 TCP streams, now 11Gbps w/ multiple
RX/TX rings enabled.

It is not enabled by default; it will be switched on after more
tests.

534ccd7bbf Replace all resource occurrences of '0UL/~0UL' with '0/~0'.
Summary:
The idea behind this is '~0ul' is well-defined, and casting to uintmax_t, on a
32-bit platform, will leave the upper 32 bits as 0.  The maximum range of a
resource is 0xFFF.... (all bits of the full type set).  By dropping the 'ul'
suffix, C type promotion rules apply, and the sign extension of ~0 on 32 bit
platforms gets it to a type-independent 'unsigned max'.

5db9ed8062 If callout_stop_safe() noted that the callout is currently executing,
but next invocation is cancelled while migrating,
sleepq_check_timeout() needs to be informed that the callout is
stopped.  Otherwise the thread switches off CPU and never become
runnable, since running callout could have already raced with us,
while the migrating and cancelled callout could be one which is
expected to set TDP_TIMOFAIL flag for us.  This contradicts with the
expected behaviour of callout_stop() for other callers, which
e.g. decrement references from the callout callbacks.

Add a new flag CS_MIGRBLOCK requesting report of the situation as
'successfully stopped'.
