2016-03-13csum: Update csum_block_add to use rotate instead of byteswapAlexander Duyck1-6/+6
The code for csum_block_add was doing a funky byteswap to swap the even and odd bytes of the checksum if the offset was odd. Instead of doing this we can save ourselves some trouble and just shift by 8 as this should have the same effect in terms of the final checksum value and only requires one instruction. In addition we can update csum_block_sub to just use csum_block_add with a inverse value for csum2. This way we follow the same code path as csum_block_add without having to duplicate it.

2016-03-13gro: Defer clearing of flush bit in tunnel pathsAlexander Duyck4-11/+5
This patch updates the GRO handlers for GRE, VXLAN, GENEVE, and FOU so that we do not clear the flush bit until after we have called the next level GRO handler. Previously this was being cleared before parsing through the list of frames, however this resulted in several paths where either the bit needed to be reset but wasn't as in the case of FOU, or cases where it was being set as in GENEVE. By just deferring the clearing of the bit until after the next level protocol has been parsed we can avoid any unnecessary bit twiddling and avoid bugs.

Yuval Mintz says: ==================== qed: Management firmware updates This series contains several changes to driver interaction with the management fw.

2016-03-11qed: Enlrage the drain timeoutYuval Mintz1-2/+2
In the scenario where slowpath configuration isn't passing due to various pause configurations affecting the chip, the theoretical time required in worst-case-scenario to empty hw fifos sufficiently to guarantee that slowpath configuration would flow is currently insufficient.

2016-03-11qed: Major changes to MB lockingTomer Tayar2-97/+167
Driver interaction with the managemnt firmware is done via mailbox commands which the management firmware periodically sample, as well as placing of additional data in set places in the shared memory. Each PF has a single designated mailbox address, and all flows that require messaging to the management should use it. This patch does 2 things: 1. It re-defines the critical section surrounding the mailbox sending - that section should include the setting of the shared memory as well as the sending of the command [otherwise a race might send a command with the data of a different command]. 2. It moves the locking scheme from using mutices into using spinlocks. This lays the groundwork for sending MFW commands from non-sleepable contexts.

2016-03-11qed: Prevent MF link notificationsSudarsana Reddy Kalluru2-1/+9
When device is configured for Multi-function mode, some older management firmware might incorrectly notify interfaces of link changes while they haven't requested the physical link configuration to be set. This can create bizzare race conditions where unloading interfaces are getting notified that the link is up. Let the driver compensate - store the logical requested state of the link and don't propagate notifications after protocol driver explicitly requires the link to be unset.

This patchset introduces cls_flower hardware offload support over ConnectX-4 driver, more hardware vendors are welcome to use it too.

It also extends the support to an additional tc action - skbedit mark operation. NIC driver that was used is ConnectX-4. Feature is off by default and could be turned on using ethtool.

2016-03-10net-next: mediatek: add support for MT7623 ethernetJohn Crispin2-0/+2228
Add ethernet support for MediaTek SoCs from the MT7623 family. These have dual GMAC. Depending on the exact version, there might be a built-in Gigabit switch (MT7530). The core does not have the typical DMA ring setup. Instead there is a linked list that we add descriptors to. There is only one linked list that both MACs use together. There is a special field inside the TX descriptors called the VQID. This allows us to assign packets to different internal queues. By using a separate id for each MAC we are able to get deterministic results for BQL. Additionally we need to provide the core with a block of scratch memory that is the same size as the RX ring and data buffer. This is really needed to make the HW datapath work. Although the driver does not support this yet, we still need to assign the memory and tell the core about it for RX to work.

We need to enable interrupts before we register our network device, so that we don't loose link up interrupts. Allocate rx queues based on interrupt type. Set number of tx/rx queues in probe function only. Also adds check for some invalid configurations. This patch series has been created against net-next tree and includes patches on cxgb4vf driver. We have included all the maintainers of respective drivers. Kindly review the change and let us know in case of any review comments. ==================== Signed-off-by: David S.

2016-03-10cxgb4vf: Configure queue based on resource and interrupt typeHariprasad Shenai1-71/+94
The Queue Set Configuration code was always reserving room for a Forwarded interrupt Queue even in the cases where we weren't using it. Figure out how many Ports and Queue Sets we can support. This depends on knowing our Virtual Function Resources and may be called a second time if we fall back from MSI-X to MSI Interrupt Mode. This change fixes that problem.
