Packet scheduler guarantees there won't be multiple senders for the same queue and as we use q_idx for multi_send_data the spinlock is redundant. Signed-off-by:

The rndis header is 116 bytes big and can be placed in the default head room that will be available in the skb. Since the netvsc packet is less than 48 bytes, we can use the skb control buffer for the netvsc packet. With these changes we don't need to ask for additional head room. Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-12-01 This series contains updates to i40e and i40evf only. Helin adds new fields to i40e_vsi to store user configured RSS config data and the code to use it. Also renamed RSS items to clarify functionality and scope to users. Fixed a confusing kernel message of enabling RSS size by reporting it together with the hardware maximum RSS size. Anjali fixes the issue of forcing writeback too often causing us to not benefit from NAPI. Jesse adds a prefetch for data early in the transmit path to help immensely for pktgen and forwarding workloads. Fixed the i40e driver that was possibly sleeping inside critical section of code. Carolyn fixes an issue where adminq init failures always provided a message that NVM was newer than expected, when this is not always the case for init_adminq failures. Fixed by adding a check for that specific error condition and a different helpful message otherwise. Mitch fixes error message by telling the user which VF is being naughty, rather than making them guess. Updated the queue_vector array from a statically-sized member of the adapter structure, to a dynamically-allocated and -sized array. This reduces the size of the adapter structure and allows us to support any number of queue vectors in the future without changing the code. ==================== Signed-off-by: -

With the final edition of the patches to remove sleeps from the driver's entry points, the grab_rtnl argument is no longer needed, so partially revert the commit that added it. Change-ID: Ib9778476242586cc9e58b670f5f48d415cb59003 Signed-off-by:

The driver was being called by VLAN, bonding, teaming operations that expected to be able to hold locks like rcu_read_lock(). This causes the driver to be held to the requirement to not sleep, and was found by the kernel debug options for checking sleep inside critical section, and the locking validator.

Instead of awkwardly keeping a fixed array of pointers in the adapter struct and then allocating ring structs individually, just keep a single pointer and allocate a single blob for the arrays. This simplifies code, shrinks the adapter structure, and future-proofs the driver by not limiting the number of rings we can handle.

If, upon a midnight dreary, the PF returns ERR_PARAM when the VF is requesting resources, that's fatal. Either the firmware or NVM is badly, badly misconfigured, or this VF has been disabled due to a previous VF driver sending a bunch of bogus messages. Either way, there is no recovery from this. Don't ponder weak and weary, just quit. Change-ID: I09d9f16cc4ee7fec3b57646a289d33838c1c5bf5 Signed-off-by:

This patch fixes an issue where adminq init failures always provided a message that NVM was newer than expected. This is not always the case for init_adminq failures. Without this patch, if adminq init fails for any reason, newer NVM message would be given. This problem is fixed by adding a check for that specific error condition and a different hopefully helpful message otherwise. Change-ID: Iaeaebee4e398989eae40bb70f943ab66a3a521a5 Signed-off-by:

Issue a prefetch for data early in the transmit path. This should not be generally needed for Tx traffic, but it helps immensely for pktgen workloads and should help for forwarding workloads as well. Change-ID: Iefee870c20599e0c4240e1d8637e4f16b625f83a Signed-off-by:

This patch fixes the issue of forcing WB too often causing us to not benefit from NAPI. Without this patch we were forcing WB/arming interrupt too often taking away the benefits of NAPI and causing a performance impact. With this patch we disable force WB in the clean routine for X710 and XL710 adapters. X722 adapters do not enable interrupt to force a WB and benefit from WB_ON_ITR and hence force WB is left enabled for those adapters. For XL710 and X710 adapters if we have less than 4 packets pending a software Interrupt triggered from service task will force a WB. This patch also changes the conditions for setting RS bit as described in code comments. This optimizes when the HW does a tail bump amd when it does a WB. It also optimizes when we do a wmb.

The 'sc' ISDN driver relies on using readl() to access ISA I/O memory. This has been deprecated and produced warnings since linux-2.3.23, disabled by default since 2.4.10 and finally removed in 2.6.5. I found this because the compiling the driver for ARM produces a warning: In file included from ../drivers/isdn/sc/includes.h:8:0, from ../drivers/isdn/sc/init.c:13: ../arch/arm/include/asm/io.h:115:21: note: expected 'const volatile void *' but argument is of type 'long unsigned int' It is pretty clear that this driver has not been used for a long time and there is no point fixing it now, so let's remove it.
