The BKL push down added some BKL into the open callback of the virtual
driver. The driver is really simple and need no such locking and so just
remove it.Signed-off-by: Marcel Holtmann
-
The virtual driver still uses a home grown way of waiting for events and
so just replace it with wait_event_interruptible. And while at it remove
the useless access_ok() checks.Signed-off-by: Marcel Holtmann
-
Allowing to specify a specific misc minor number for the virtual driver
is pretty much useless and nobody is using this feature. So just remove
it and use MISC_DYNAMIC_MINOR all the time.Signed-off-by: Marcel Holtmann

The Bluetooth source uses some endian conversion helpers, that in the end
translate to kernel standard routines. So remove this obfuscation since it

With all the last patchsets going in for 82599 feature enablement, the
driver version needs to be increased for better identification.Signed-off-by: Peter P Waskiewicz Jr
Signed-off-by: Jeff Kirsher
Signed-off-by: David S. Miller -
82599 has a FW running that helps manage the internal SFI PHY. There are
also a number of pre-production samples of these SFI-based devices in the
field. This patch adds a check to look for the firmware running on all
SFP+ based adapters, and displays a warning to the system log if a
pre-production adapter is identified. The driver will continue loading
though, with no functional degradation.Also remove an old function prototype from ixgbe_82599.c that isn't being
used.Signed-off-by: Peter P Waskiewicz Jr

This patch adds the functions for ixgbe to initialize Flow Director. It
also has the function APIs to add Flow Director filters from the base
driver. This also includes ATR, Application Targeted Routing, which is a
feature set of Flow Director. This is the hash-based mechanism to
automatically identify flows and add filters based on the hash, and direct
the Rx of that flow back to that same CPU.Signed-off-by: Peter P Waskiewicz Jr

Signed-off-by: David S. Miller -
Flow Director is a Rx filter mechanism designed to match Rx flows back to
the same CPU that the flow's Tx occurred from. This patch adds the first

This patch moves the tx cleanup processing out of the MSI-X interrupt
processing and gives it it's own napi routine. This allows the driver to
process TX cleanup in a polling context instead of in an interrupt context
which prevents TX from starving RX.Signed-off-by: Alexander Duyck

The v_idx value was being used as both a bitmask and an index. This change
makes it so that the q_vector contains the index and allows for much of the
code to be simplified since disabling a q_vector involves only clearing one
bit in the interrupt bitmask.Signed-off-by: Alexander Duyck

This patch changes the driver so that it uses rx_buffer_info->dma to
determine if it needs to unmap the page instead of sh_info->nr_frags. This
helps to prevent a cache line miss when receiving small packets as the
rx_buffer_info data should already be in the cache.Signed-off-by: Alexander Duyck

Fix autoneg restart issues in flow control path which might create
endless link flickering due to known timing issues with 82599
adapters.Signed-off-by: Mallikarjuna R Chilakala
Signed-off-by: Jeff Kirsher
Signed-off-by: David S. Miller -
82599 supports multispeed fiber optical modules (10Gbps/1Gbps). Some
scenarios can cause the autotry mechanism to not negotiate link properly.
What needs to happen is the driver must flap the Tx laser to induce an Rx
Loss of Signal on the link partner. This will restart the autotry
mechanism to get link into a known state. The software definable pin (SDP)
3 on the 0x10fb NIC is wired to cause a Tx LOS event, which triggers the
Rx LOS we require.Signed-off-by: Peter P Waskiewicz Jr

When reprogramming the 82599 analog PHY to either SFI optical or Direct
Attach Twinax, we need to restart the DSP in the PHY. The current method
can cause contention with our FW which is managing PHY state, and will
cause unexpected link flaps. This patch fixes the DSP restart by issuing
an AN_RESTART in the MAC, which will properly propagate the DSP restart to
the PHY. This ensures we don't collide with the FW.Signed-off-by: Peter P Waskiewicz Jr

Patch fixes the bug at
http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1903when SW rfkill is invoked by 'iwconfig txpower off',
the existing connection disassociates and led off command is sent
to the device which returns error as rfkill is 'true'.Patch fixes this by just avoiding sending the led off/on command when
disassociated. The main purpose of the led_disassociate callback
is to start or stop the blinking.
There are three states in led
1) Always on when radio is on
2) Always off when radio is off
3) blink when associated and if there is some traffic.In this callback 'allow_blinking' needs to be set false
when associated, as LED will be always on.Signed-off-by: Abhijeet Kolekar

When I added socket accounting to tun I inadvertently introduced
spurious wake-up events that kills qemu performance. The problem
occurs when qemu polls on the tun fd for read, and then transmits
packets. For each packet transmitted, we will wake up qemu even
if it only cares about read events.Now this affects all sockets, but it is only a new problem for
tun. So this patch tries to fix it for tun first and we can then
look at the problem in general.Signed-off-by: Herbert Xu
