It happens that if a packet arrives in a VC between the call to open it on
the hardware and the call to change the backend to br2684, br2684_regvcc
processes the packet and oopses dereferencing skb->dev because it is
NULL before the call to br2684_push().

There are many possible ways to add this "salt", thus I made this
patch to be the last in the series to change it if required.

Currently I propose to use the struct net pointer itself as this 
salt, but since this pointer is most often cache-line aligned, shift 
this right to eliminate the bits, that are most often zeroed.

After this, simply add this mix to prepared hashfn-s.

For CONFIG_NET_NS=n case this salt is 0 and no changes in hashfn
appear.

Although this hash takes addresses into account, the ehash chains

I just noticed "cat /proc/net/raw" was buggy, missing '\n' separators.

Selected device feature bits can be propagated to VLAN devices, so we
can make use of TX checksum offload and TSO on VLAN-tagged packets.
However, if the physical device does not do VLAN tag insertion or
generic checksum offload then the test for TX checksum offload in
dev_queue_xmit() will see a protocol of htons(ETH_P_8021Q) and yield
false.

This splits the checksum offload test into two functions:

- can_checksum_protocol() tests a given protocol against a feature bitmask

- dev_can_checksum() first tests the skb protocol against the device
  features; if that fails and the protocol is htons(ETH_P_8021Q) then
  it tests the encapsulated protocol against the effective device
  features for VLANs

Right now, any time we set a primary transport we set
the changeover_active flag.  As a result, we invoke SFR-CACC
even when there has been no changeover events.

Only set changeover_active, when there is a true changeover
event, i.e. we had a primary path and we are changing to
another transport.

Ingo's system is still seeing strange behavior, and he
reports that is goes away if the rest of the deferred
accept changes are reverted too.

Therefore this reverts e4c78840
("[TCP]: TCP_DEFER_ACCEPT updates - dont retxmt synack") and
539fae89 ("[TCP]: TCP_DEFER_ACCEPT
updates - defer timeout conflicts with max_thresh").

In IBSS mode prior to join/creation of new IBSS it is possible that
a frame from unknown station is received and an ibss_add_sta() is
called. This will cause a warning in rate_lowest_index() since the
list of supported rates of our station is not initialized yet.

The fix is to add ibss stations with a rate we received that frame
at; this single-element set will be extended later based on beacon
data. Also there is no need to store stations from a foreign IBSS.
