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.

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. This increases such a drain request to the theoretical maximum. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>

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.

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.

2016-03-11net: dsa: mv88e6xxx: avoid writing the same modeVivien Didelot1-8/+13
There is no need to change the 802.1Q port mode for the same value. Thus avoid such message: [ 401.954836] dsa dsa@0 lan0: 802.1Q Mode: Disabled (was Disabled) Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Tested-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

2016-03-11net: dsa: mv88e6xxx: read then write PVIDVivien Didelot1-4/+26
The port register 0x07 contains more options than just the default VID, even though they are not used yet. So prefer a read then write operation over a direct write. This also allows to keep track of the change through dynamic debug. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Tested-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

2016-03-11net: dsa: mv88e6xxx: rework port state setterVivien Didelot2-22/+34
Apply a few non-functional changes on the port state setter: * add a dynamic debug message with state names to track changes * explicit states checking instead of assuming their numeric values * lock mutex only once when changing several port states * use bitmap macros to declare and access port_state_update_mask Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Tested-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

2016-03-11sh_eth: advance 'rxdesc' later in sh_eth_ring_format()Sergei Shtylyov1-3/+4
Iff dma_map_single() fails, 'rxdesc' should point to the last filled RX descriptor, so that it can be marked as the last one, however the driver would have already advanced it by that time. In order to fix that, only fill an RX descriptor once all the data for it is ready. Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> Signed-off-by: David S.
