Add a new constant ETH_P_802_3_MIN, the minimum ethernet type for
an 802.3 frame. Frames with a lower value in the ethernet type field
are Ethernet II.

Also update all the users of this value that David Miller and
I could find to use the new constant.

Also correct a bug in util.c. The comparison with ETH_P_802_3_MIN
should be >= not >.

As suggested by Jesse Gross.

Compile tested only.

The commit 40893fd0(net: switch to use skb_probe_transport_header())
involes a new error accidently. When NET_SKBUFF_DATA_USES_OFFSE is
not enabled, below compile error happens:

  CC      net/packet/af_packet.o
  net/packet/af_packet.c: In function ‘packet_sendmsg_spkt’:
  net/packet/af_packet.c:1516:2: error: implicit declaration of function ‘skb_probe_transport_header’ [-Werror=implicit-function-declaration]
  cc1: some warnings being treated as errors
  make[2]: *** [net/packet/af_packet.o] Error 1
  make[1]: *** [net/packet] Error 2
  make: *** [net] Error 2

As it seems skb_probe_transport_header() is not related to
NET_SKBUFF_DATA_USES_OFFSE, we should move the definition of
skb_probe_transport_header() out of scope of
NET_SKBUFF_DATA_USES_OFFSE macro.

In case of fixed speed set up for a NIC (e.g. ethtool -s eth0 autoneg off speed
100 duplex full) with an ethernet cable plugged off, the mentioned algorithm
slows down a NIC speed, so further cable hook-up leads to nonoperable link state.

Move the protection of netns_frags.nqueues updates under the LRU_lock,

The LRU list is protected by its own lock, since commit 3ef0eb0d
(net: frag, move LRU list maintenance outside of rwlock), and
no-longer by a read_lock.

This makes it possible, to remove the inet_frag_queue, which is about
to be "evicted", from the LRU list head.  This avoids the problem, of
several CPUs grabbing the same frag queue.

Note, cannot remove the inet_frag_lru_del() call in fq_unlink()
called by inet_frag_kill(), because inet_frag_kill() is also used in
other situations.  Thus, we use list_del_init() to allow this
double list_del to work.

Sometimes, we need probe and set the transport header for packets (e.g from
untrusted source). This patch introduces a new helper
skb_probe_transport_header() which tries to probe and set the l4 header through
skb_flow_dissect(), if not just set the transport header to the hint passed by
caller.

For untrusted packets with partial checksum, we need to set the transport header
for precise packet length estimation. We can just let skb_pratial_csum_set() to
do this to avoid extra call to skb_flow_dissect() and simplify the caller.

Pull IOMMU fixes from Joerg Roedel:
 "Here are some fixes which have collected since Linux v3.9-rc1.

  The most important one fixes a long-standing regressen which make
  re-hotplugged devices unusable when AMD IOMMU is used.

  The other patches fix build issues (build regression on OMAP and a
  section mismatch).  One patch just removes a duplicate header include."

* tag 'iommu-fixes-v3.9-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu:
  iommu/amd: Make sure dma_ops are set for hotplug devices
  x86, io_apic: remove duplicated include from irq_remapping.c
  iommu: OMAP: build only on OMAP2+
  amd_iommu_init: remove __init from amd_iommu_erratum_746_workaround

Commit 06ae43f3 ("Don't bother with redoing rw_verify_area() from
default_file_splice_from()") lost the checks to test existence of the
write/aio_write methods.  My apologies ;-/

repeating it for every buffer, after all), but for now this is the
obvious minimal fix.
