2d30c961db Rename definition of IEEE80211_FC1_WEP to IEEE80211_FC1_PROTECTED.
The origin of WEP comes from IEEE Std 802.11-1997 where it defines
whether the frame body of MAC frame has been encrypted using WEP
algorithm or not.
IEEE Std. 802.11-2007 changes WEP to Protected Frame, indicates
whether the frame is protected by a cryptographic encapsulation
algorithm.

bb4969cec5 Add option USB_HOST_ALIGN to configs that contain 'device usb'. Setting
this to the cache line size is required to avoid data corruption on armv4
and armv5, and improves performance on armv6, in both cases by avoiding
partial cacheline flushes for USB IO.

ab2de99290 Use the 'Virtual Interrupt Delivery' feature of Intel VT-x if supported by
hardware. It is possible to turn this feature off and fall back to software
emulation of the APIC by setting the tunable hw.vmm.vmx.use_apic_vid to 0.

We now start handling two new types of VM-exits:

APIC-access: This is a fault-like VM-exit and is triggered when the APIC
register access is not accelerated (e.g. apic timer CCR). In response to
this we do emulate the instruction that triggered the APIC-access exit.

APIC-write: This is a trap-like VM-exit which does not require any instruction
emulation but it does require the hypervisor to emulate the access to the
specified register (e.g. icrlo register).

Introduce 'vlapic_ops' which are function pointers to vector the various
vlapic operations into processor-dependent code. The 'Virtual Interrupt
Delivery' feature installs 'ops' for setting the IRR bits in the virtual
APIC page and to return whether any interrupts are pending for this vcpu.

207475f6fd Remove aicasm as a build dependency. It made sense when the ahc and ahd
drivers and their firmware were under active development, but those days
have passed.  The firmware now exists in pre-compiled form, no longer
dependent on it's sources or on aicasm.  If you wish to rebuild the
firmware from source, the glue still exists under the 'make firmware'
target in sys/modules/aic7xxx.

This also fixes the problem introduced with r257777 et al with building
kernels the old fashioned way in sys/$arch/compile/$CONFIG when the
ahc/ahd drivers were included.

23ea3a1c59 Fix a bug introduced in r260167 related to VM-exit tracing.
Keep a copy of the 'rip' and the 'exit_reason' and use that when calling
vmx_exit_trace(). This is because both the 'rip' and 'exit_reason' can
be changed by 'vmx_exit_process()' and can lead to very misleading traces.

c74f1326f9 Fix the geom mappings for WR1043ND.
The uboot mapping is only 128KiB (0x20000) and not 2MiB (0x200000).

Dynamically adjust kernel and rootfs mappings based on the
geom_uncompress(4) magic.

This makes the built images more reliable by accepting changes on kernel
size transparently and matches the images built with zrouter and

41068e3dad It is 2014 and we have a new version of netmap.
Most relevant features:

- netmap emulation on any NIC, even those without native netmap support.

  On the ixgbe we have measured about 4Mpps/core/queue in this mode,
  which is still a lot more than with sockets/bpf.

- seamless interconnection of VALE switch, NICs and host stack.

  If you disable accelerations on your NIC (say em0)

        ifconfig em0 -txcsum -txcsum

  you can use the VALE switch to connect the NIC and the host stack:

        vale-ctl -h valeXX:em0

  allowing sharing the NIC with other netmap clients.

- THE USER API HAS SLIGHTLY CHANGED (head/cur/tail pointers
  instead of pointers/count as before). This was unavoidable to support,
  in the future, multiple threads operating on the same rings.
  Netmap clients require very small source code changes to compile again.
      On the plus side, the new API should be easier to understand
  and the internals are a lot simpler.

The manual page has been updated extensively to reflect the current
features and give some examples.

This is the result of work of several people including Giuseppe Lettieri,
Vincenzo Maffione, Michio Honda and myself, and has been financially
supported by EU projects CHANGE and OPENLAB, from NetApp University
Research Fund, NEC, and of course the Universita` di Pisa.
