2014-09-23net: bcmgenet: call bcmgenet_dma_teardown in bcmgenet_fini_dmaFlorian Fainelli1-53/+52
We should not be manipulaging the DMA_CTRL registers directly by writing 0 to them to disable DMA. This is an operation that needs to be timed to make sure the DMA engines have been properly stopped since their state machine stops on a packet boundary, not immediately. Make sure that tha bcmgenet_fini_dma() calls bcmgenet_dma_teardown() to ensure a proper DMA engine state. As a result, we need to reorder the function bodies to resolve the use dependency.

2014-09-23net: bcmgenet: fix TX reclaim accounting for fragmentsFlorian Fainelli1-1/+4
The GENET driver supports SKB fragments, and succeeds in transmitting them properly, but when reclaiming these transmitted fragments, we will only update the count of free buffer descriptors by 1, even for SKBs with fragments. This leads to the networking stack thinking it has more room than the hardware has when pushing new SKBs, and backing off consequently because we return NETDEV_TX_BUSY. Fix this by accounting for the SKB nr_frags plus one (itself) and update ring->free_bds accordingly with that value for each iteration loop in __bcmgenet_tx_reclaim().

2014-09-22macvlan: allow to enqueue broadcast pkt on virtual deviceNicolas Dichtel1-1/+2
Since commit 412ca1550cbe ("macvlan: Move broadcasts into a work queue"), the driver uses tx_queue_len of the master device as the limit of packets enqueuing. Problem is that virtual drivers have this value set to 0, thus all broadcast packets were rejected. Because tx_queue_len was arbitrarily chosen, I replace it with a static limit of 1000 (also arbitrarily chosen).

2014-09-22mlx4: Fix mlx4 reg/unreg mac to work properly with 0-mac addressesJack Morgenstein1-4/+7
There is a chance that the VF mlx4 RoCE driver (mlx4_ib) may see a 0-mac as the current default MAC address when a RoCE interface first comes up. In this case, the RoCE driver registers the 0-mac to get its MAC index -- used in the INIT2RTR transition when it creates its proxy Q1 qp's. If we do not allow QP1 to be created, the RoCE driver will not come up. If we do not register the 0-mac, but simply use a random mac-index, QP1 will attempt to send packets with an someone's else source MAC which will get the system into more troubled. Since a 0-mac was previously used to indicate a free slot, this leads to errors, both when the 0-mac is registered and when it is unregistered. The required fix is to check in addition that the slot containing the 0-mac has a reference count of zero. Additionally, when comparing MAC addresses, need to mask out the 2 MSBs of the u64 mac on both sides of the comparison. Note that when the EN driver (mlx4_en) comes up, it set itself a proper mac --> the RoCE driver gets to be notified on that and further handing is done with the update qp command, as was added by commit 9433c188915c ("IB/mlx4: Invoke UPDATE_QP for proxy QP1 on MAC changes").

Ethan Zhao cleans up ixgbe and ixgbevf by removing bd_number from the adapter struct because it is not longer useful. Mark fixes ixgbe where if a hardware transmit timestamp is requested, an uninitialized workqueue entry may be scheduled. Added a check for a PTP clock to avoid that. Jacob provides a number of cleanups for ixgbe. Since we may call ixgbe_acquire_msix_vectors() prior to registering our netdevice, we should not use the netdevice specific printk and use e_dev_warn() instead. Similar to how ixgbevf handles acquiring MSI-X vectors, we can return an error code instead of relying on the flag being set. This makes it more clear that we have failed to setup MSI-X mode and will make it easier to consolidate MSI-X related code into a single function. In the case of disabling DCB, it is not an error since we still can function, we just have to let the user know. So use e_dev_warn() instead of e_err(). Added warnings for other features that are disabled when we are without MSI-X support. Cleanup flags that are no longer used or needed. ==================== Signed-off-by: David S.

2014-09-20net/mlx4_en: Add mlx4_en_get_cqe helperIdo Shamay4-4/+11
This function derives the base address of the CQE from the CQE size, and calculates the real CQE context segment in it from the factor (this is like before). Before this change the code used the factor to calculate the base address of the CQE as well. The factor indicates in which segment of the cqe stride the cqe information is located. For 32-byte strides, the segment is 0, and for 64 byte strides, the segment is 1 (bytes 32..63). Using the factor was ok as long as we had only 32 and 64 byte strides. However, with larger strides, the factor is zero, and so cannot be used to calculate the base of the CQE. The helper uses the same method of CQE buffer pulling made by all other components that reads the CQE buffer (mlx4_ib driver and libmlx4).

2014-09-20net/mlx4_core: Enable CQE/EQE stride supportIdo Shamay4-4/+100
This feature is intended for archs having cache line larger then 64B. Since our CQE/EQEs are generally 64B in those systems, HW will write twice to the same cache line consecutively, causing pipe locks due to he hazard prevention mechanism. For elements in a cyclic buffer, writes are consecutive, so entries smaller than a cache line should be avoided, especially if they are written at a high rate. Reduce consecutive writes to same cache line in CQs/EQs, by allowing the driver to increase the distance between entries so that each will reside in a different cache line. Until the introduction of this feature, there were two types of CQE/EQE: 1. 32B stride and context in the [0-31] segment 2. 64B stride and context in the [32-63] segment This feature introduces two additional types: 3. 128B stride and context in the [0-31] segment (128B cache line) 4. 256B stride and context in the [0-31] segment (256B cache line) Modify the mlx4_core driver to query the device for the CQE/EQE cache line stride capability and to enable that capability when the host cache line size is larger than 64 bytes (supported cache lines are 128B and 256B). The mlx4 IB driver and libmlx4 need not be aware of this change. The PF context behaviour is changed to require this change in VF drivers running on such archs.

Arend van Spriel sends a trio of minor brcmfmac fixes, including a fix for a Kconfig/build issue, a fix for a crash (null reference), and a regression fix related to event handling on a P2P interface. Hante Meuleman follows-up with a brcmfmac fix for a memory leak. Johannes Stezenbach brings an ath9k_htc fix for a regression related to hardware decryption offload. Marcel Holtmann delivers a one-liner to properly mark a device ID table in rfkill-gpio. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2014-09-20bnx2x: Add a fallback multi-function mode NPAR1.5Yuval Mintz3-21/+42
When using new Multi-function modes it's possible that due to incompatible configuration management FW will fallback into an existing mode. Notice that at the moment this fallback is exactly the same as the already existing switch-independent multi-function mode, but we still use existing infrastructure to hold this information [in case some small differences will arise in the future].

2014-09-20bnx2x: Changes with storage & MAC macrosDmitry Kravkov5-42/+54
Rearrange macros to query for storage-only modes in different MF environment. Improves the readibility and maintainability of the code. E.g.: - if (IS_MF_STORAGE_SD(bp) || IS_MF_FCOE_AFEX(bp)) + if (IS_MF_STORAGE_ONLY(bp)) In addition, this removes the need for bnx2x_is_valid_ether_addr().
