vhost: vhost TX zero-copy support
>From: Shirley Ma <mashirle@us.ibm.com>
This adds experimental zero copy support in vhost-net,
disabled by default. To enable, set
experimental_zcopytx module option to 1.
This patch maintains the outstanding userspace buffers in the
sequence it is delivered to vhost. The outstanding userspace buffers
will be marked as done once the lower device buffers DMA has finished.
This is monitored through last reference of kfree_skb callback. Two
buffer indices are used for this purpose.
The vhost-net device passes the userspace buffers info to lower device
skb through message control. DMA done status check and guest
notification are handled by handle_tx: in the worst case is all buffers
in the vq are in pending/done status, so we need to notify guest to
release DMA done buffers first before we get any new buffers from the
vq.
One known problem is that if the guest stops submitting
buffers, buffers might never get used until some
further action, e.g. device reset. This does not
seem to affect linux guests.

bnx2: Close device if tx_timeout reset fails
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.

Separate handling of irq type flags variable from the irq_flags request_irq variable
Commit
5f77898de17ff983ff0e2988b73a6bdf4b6f9f8b 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.

net/ps3: Fix gelic RX DMA restart
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.

bnx2x: Multiple concurrent l2 traffic classes
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.

mac80211: allow driver to disconnect after resume
In WoWLAN, devices may use crypto keys for TX/RX
and could also implement GTK rekeying. If the
driver isn't able to retrieve replay counters and
similar information from the device upon resume,
or if the device isn't responsive due to platform
issues, it isn't safe to keep the connection up
as GTK rekey messages from during the sleep time
could be replayed against it.
The only protection against that is disconnecting
from the AP. Modifying mac80211 to do that while
it is resuming would be very complex and invasive
in the case that the driver requires a reconfig,
so do it after it has resumed completely. In that
case, however, packets might be replayed since it
can then only happen after TX/RX are up again, so
mark keys for interfaces that need to disconnect
as "tainted" and drop all packets that are sent
or received with those keys.

ath9k_hw: Fix incorrect key_miss handling
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
status handling makes much more sense.
This patch addresses an issue with STA not reporting MIC failure events
resulting in STA being disconnected immediately.
