It was discovered by Roberto Bergo, that RTS/DTR signals are inverted after
the boot, because it was causing him problems with hardware controlled modem
connected on ttyAM0. Todd Valentic came with this patch for the issue.

In certain circumstances, like WoWLAN scenarios,
devices may implement (partial) GTK rekeying on
the device to avoid waking up the host for it.
In order to successfully go through GTK rekeying,
the KEK, KCK and the replay counter are required.
Add API to let the supplicant hand the parameters
to the driver which may store it for future GTK
rekey operations.
Note that, of course, if GTK rekeying is done by
the device, the EAP frame must not be passed up
to userspace, instead a rekey event needs to be
sent to let userspace update its replay counter.

When in suspend/wowlan, devices might implement crypto
offload differently (more features), and might require
reprogramming keys for the WoWLAN (as it is the case
for Intel devices that use another uCode image). Thus
allow the driver to iterate all keys in this context.

There is a bug in free_unnecessary_pages() that causes it to
attempt to free too many pages in some cases, which triggers the
BUG_ON() in memory_bm_clear_bit() for copy_bm. Namely, if
count_data_pages() is initially greater than alloc_normal, we get
to_free_normal equal to 0 and "save" greater from 0. In that case,
if the sum of "save" and count_highmem_pages() is greater than
alloc_highmem, we subtract a positive number from to_free_normal.
Hence, since to_free_normal was 0 before the subtraction and is
an unsigned int, the result is converted to a huge positive number
that is used as the number of pages to free.
Fix this bug by checking if to_free_normal is actually greater
than or equal to the number we're going to subtract from it.

locks_alloc_lock() assumed that the allocated struct file_lock is
already initialized to zero members. This is only true for the first
allocation of the structure, after reuse some of the members will have
random values.
This will for example result in passing random fl_start values to
userspace in fuse for FL_FLOCK locks, which is an information leak at
best.
Fix by reinitializing those members which may be non-zero after freeing.

This patch add an unsolicited notification of the DCBX negotiated

message is identical to the aggregated CEE get operation and holds all

The following couple of patches add dcbnl an unsolicited notification of
the the DCB configuration for the CEE flavor of the DCBX protocol. This
is useful when the user-mode DCB client is not responsible for
conducting and resolving the DCBX negotiation (either because the DCBX
stack is embedded in the HW or the negotiation is handled by another
agent in the host), but still needs to get the negotiated parameters.
This functionality already exists for the IEEE flavor of the DCBX
protocol and these patches add it to the older CEE flavor.
The first patch extends the CEE attribute GET operation to include not
only the peer information, but also all the pertinent local
configuration (negotiated parameters). The second patch adds and export
a CEE specific notification routine.

1) S5P64X0 channel 1
2) S5PV210 channel 1
The FIFO data level supported in the above SoCs either 64 or
256 bytes depending on the channel. Because of this the TX_DONE
is the 25 bit in the status register.
The existing macro works for the following scenarios
1) S3C6410 all channels
2) S5PC100 all channels
The FIFO data level supported in the above SoCs 64 bytes

in the status register.
So when we use the existing macro for the non-working SoCs
it is not anding with the TX_DONE bit for transmission status check.

Fanouts allow packet capturing to be demuxed to a set of AF_PACKET
sockets. Two fanout policies are implemented:
1) Hashing based upon skb->rxhash
2) Pure round-robin
An AF_PACKET socket must be fully bound before it tries to add itself
to a fanout. All AF_PACKET sockets trying to join the same fanout
must all have the same bind settings.
Fanouts are identified (within a network namespace) by a 16-bit ID.
The first socket to try to add itself to a fanout with a particular
ID, creates that fanout. When the last socket leaves the fanout
(which happens only when the socket is closed), that fanout is
destroyed.

If the rx ring is completely empty, then the device may never fire an rx
interrupt. Unfortunately, the rx interrupt is what triggers populating the
rx ring with fresh buffers, so this will cause networking to lock up.
This patch replenishes the skb in recv descriptor as soon as it is
peeled off while processing rx completions. If the skb/buffer
allocation fails, existing one is recycled and the packet in hand is
dropped. This way none of the RX desc is ever left empty, thus avoiding
starvation

As is_multicast_ether_addr returns true on broadcast packets as
well, we need to explicitly exclude broadcast packets so that
they're always flooded. This wasn't an issue before as broadcast
packets were considered to be an unregistered multicast group,
which were always flooded. However, as we now only flood such
packets to router ports, this is no longer acceptable.
