For ad-hoc mode, RA is created for each peer connected. In case of
multicast traffic new RA will be created for each multicast
address. While processing Tx packets we have to go through this
RA list. We can avoid some RA nodes by sharing same RA for both
multicast and broadcast packets.
Therefore "memset(0xff)" is used to treat multicast packet as broadcast
one while choosing RA.

Implement WoWLAN support in iwlagn. The device
supports a number of wakeup triggers and can do

As I just discovered while doing WoWLAN, HW crypto
is done wrong for GTKs: they should be programmed
for the AP station ID (in the managed mode case)
and the HW can actually deal with multiple group
keys per station as well (which is useful in IBSS
RSN but that I've chosen not to use this).
To fix all this, modify the way keys are sent to
the device and key offsets are allocated. After
these changes, key offsets are stored into the
hw_key_idx which we can then track for the key
lifetime, not relying on our sta_cmd array. WEP
default keys get special treatment, of course.
Additionally, since I had the API for it, we can
now pre-fill TKIP phase 1 keys for RX now that we
can obtain the P1K from mac80211, a capability I
had added for WoWLAN initially.
Finally, some keys simply don't need to be added
into the device's key cache -- a key that won't
be used for RX is only needed in the TX header,
so "pretend" to have accepted any key without
adding it into the device -- no need to use up
key space there for it.

The device specific struct is allocated together with the common iwl_bus struct

upper layer that holds a pointer to iwl_bus instead of an embedded iw_bus.
The private data given to the PCI subsystem is now iwl_bus and not iwl_priv.

Based on original patch and description from Flavio Leitner <fbl@redhat.com>
When bnx2_reset_task() is called, it will stop,
(re)initialize and start the interface to restore
the working condition.
The bnx2_init_nic() calls bnx2_reset_nic() which will
reset the chip and then calls bnx2_free_skbs() to free
all the skbs.
The problem happens when bnx2_init_chip() fails because
bnx2_reset_nic() will just return skipping the ring
initializations at bnx2_init_all_rings(). Later, the
reset task starts the interface again and the system
crashes due a NULL pointer access (no skb in the ring).
To fix it, we call dev_close() if bnx2_init_nic() fails.
One minor wrinkle to deal with is the cancel_work_sync()
call in bnx2_close() to cancel bnx2_reset_task(). The
call will wait forever because it is trying to cancel
itself and the workqueue will be stuck.
Since bnx2_reset_task() holds the rtnl_lock() and checks
for netif_running() before proceeding, there is no need
to cancel bnx2_reset_task() in bnx2_close() even if
bnx2_close() and bnx2_reset_task() are running concurrently.
The rtnl_lock() serializes the 2 calls.
We need to move the cancel_work_sync() call to
bnx2_remove_one() to make sure it is canceled before freeing
the netdev struct.

since the Rx path needs to add the address of the page to the skb.

For unicast the hardware sometimes reports MIC errors even though the
frame that it received actually contains a valid MIC - on some chips this
can happen frequently enough to trigger TKIP countermeasures.
Fix this issue by not reporting MIC errors for unicast frames with a
valid key, letting mac80211 validate the MIC instead.
Additionally, strip the MIC for all frames that the hardware considers
valid to avoid wasting CPU cycles re-validating it.

Commit 5f77898de1 does not completely
fix the problem of handling allocations with irqs disabled.. The
below patch on top of it fixes the problem completely.
Based on review by "Ivan Vecera" <ivecera@redhat.com>..
"
Small note, the root of the problem was that non-atomic allocation was requested with IRQs disabled. Your patch description does not contain wwhy were the IRQs disabled.
The function bnad_mbox_irq_alloc incorrectly uses 'flags' var for two different things, 1) to save current CPU flags and 2) for request_irq
call.
First the spin_lock_irqsave disables the IRQs and saves _all_ CPU flags (including one that enables/disables interrupts) to 'flags'. Then the 'flags' is overwritten by 0 or 0x80 (IRQF_SHARED). Finally the spin_unlock_irqrestore should restore saved flags, but these flags are now either 0x00 or 0x80. The interrupt bit value in flags register on x86 arch is 0x100.
This means that the interrupt bit is zero (IRQs disabled) after spin_unlock_irqrestore so the request_irq function is called with disabled interrupts.

Fix the condition where PS3 network RX hangs when no network
TX is occurring by calling gelic_card_enable_rxdmac() during
RX_DMA_CHAIN_END event processing.
The gelic hardware automatically clears its RX_DMA_EN flag when
it detects an RX_DMA_CHAIN_END event. In its processing of
RX_DMA_CHAIN_END the gelic driver is required to set RX_DMA_EN
(with a call to gelic_card_enable_rxdmac()) to restart RX DMA
transfers. The existing gelic driver code does not set
RX_DMA_EN directly in its processing of the RX_DMA_CHAIN_END
event, but uses a flag variable card->rx_dma_restart_required
to schedule the setting of RX_DMA_EN until next inside the
interrupt handler.
It seems this delayed setting of RX_DMA_EN causes the hang since
the next RX interrupt after the RX_DMA_CHAIN_END event where
RX_DMA_EN is scheduled to be set will not occur since RX_DMA_EN
was not set. In the case were network TX is occuring, RX_DMA_EN
is set in the next TX interrupt and RX processing continues.

Overview:
Support mapping of priorities to traffic classes and
traffic classes to transmission queues ranges in the net device.
The queue ranges are (count, offset) pairs relating to the txq
array.
This can be done via DCBX negotiation or by kernel.
As a result Enhanced Transmission Selection (ETS) and Priority Flow
Control (PFC) are supported between L2 network traffic classes.
Mapping:
This patch uses the netdev_set_num_tc, netdev_set_prio_tc_map and
netdev_set_tc_queue functions to map priorities to traffic classes
and traffic classes to transmission queue ranges.
This mapping is performed by bnx2x_setup_tc function which is
connected to the ndo_setup_tc.
This function is always called at nic load where by default it
maps all priorities to tc 0, and it may also be called by the
kernel or by the bnx2x upon DCBX negotiation to modify the mapping.
rtnl lock:
When the ndo_setup_tc is called at nic load or by kernel the rtnl
lock is already taken. However, when DCBX negotiation takes place
the lock is not taken. The work is therefore scheduled to be
handled by the sp_rtnl task.
Fastpath:
The fastpath structure of the bnx2x which was previously used
to hold the information of one tx queue and one rx queue was
redesigned to represent multiple tx queues, one for each traffic
class.
The transmission queue supplied in the skb by the kernel can no
longer be interpreted as a straightforward index into the fastpath
structure array, but it must rather be decoded to the appropriate
fastpath index and the tc within that fastpath.
Slowpath:
The bnx2x's queue object was redesigned to accommodate multiple
transmission queues. The queue object's state machine was enhanced
to allow opening multiple transmission-only connections on top of
the regular tx-rx connection.
Firmware:
This feature relies on the tx-only queue feature introduced in the
bnx2x 7.0.23 firmware and the FW likewise must have the bnx2x multi
cos support.

There is no software fallback implemented for SCTP or FCoE checksumming,
and so it should not be passed on by software devices like bridge or bonding.
For VLAN devices, this is different. First, the driver for underlying device
should be prepared to get offloaded packets even when the feature is disabled
(especially if it advertises it in vlan_features). Second, devices under
VLANs do not get replaced without tearing down the VLAN first.
This fixes a mess I accidentally introduced while converting bonding to
ndo_fix_features.
NETIF_F_SOFT_FEATURES are removed from BOND_VLAN_FEATURES because they
are unused as of commit 712ae51afd.

This patch used to contain an implementation for the alternative method,

Decryping frames on key_miss handling shouldn't be done for Michael
MIC failed frames as h/w would have already decrypted such frames
successfully anyway.
Also leaving CRC and PHY error(where the frame is going to be dropped
anyway), we are left to prcoess Decrypt error for which s/w decrypt is
selected anway and so having key_miss as a separate check doesn't serve
anything. So making key_miss handling mutually exlusive with other RX

Make sure that the 'static' keywork is at the beginning of declaration
for drivers/net/usb/kalmia.c
This gets rid of warnings like
warning: ‘static’ is not at beginning of declaration
when building with -Wold-style-declaration (and/or -Wextra which also
enables it).

This fix makes it so that the fdir_perfect_lock is initialized in all
cases. This is necessary as the fdir_filter_exit routine will always
attempt to take the lock before inspecting the filter table.

Register writes followed by a delay are required to have a flush
before the delay in order to commit the values to the register. Without
the flush, the code following the delay may not function correctly.

A typo causes routine rtl92cu_phy_rf6052_set_cck_txpower() to test the
same condition twice. The problem was found using cppcheck-1.49, and the
proper fix was verified against the pre-mac80211 version of the code.

When commands time out, corruption ensues. As lbs_complete_command()
is called without locking, the command node is mistakenly freed twice.
Also fixed up locking here in a few other places.
The nature of command timeout may be that the card didn't even
acknowledge receipt of the request. Detect this case and reset dnld_sent
so that other commands don't hang forever.
When cmdnodes are moved between the free list and the pending list,
their list heads should be reinitialized. Fixed this.
Sometimes commands are completed without actually submitting them or
removing them from cmdpendingq. We must remember to remove them from
cmdpendingq in these cases, so handle this in lbs_complete_command().
Harmless signals generated during suspend/resume were interrupting
lbs_cmd. Convert to an uninterruptible sleep to avoid this.
lbs_thread must be woken up every time there is some new work to do.
I found that when 2 commands are queued, ther completion of the first
command would not wake up lbs_thread to submit the second. Poke lbs_thread
at the end of lbs_complete_command() to fix this.

Initialize the the clock-to-TSF field of AR_USEC and the SIFS and EIFS time
registers based on the clock rate instead of relying on initvals.
With those changes, some of the hardcoded AR9287 1.3+ specific overrides
can be dropped.
