2017-06-07cxgb4: Fix tids count for ipv6 offload connectionGanesh Goudar6-31/+71
the adapter consumes two tids for every ipv6 offload connection be it active or passive, calculate tid usage count accordingly. Also change the signatures of relevant functions to get the address family.

2017-06-07nfp: advertise support for NFD ABI 0.5Jakub Kicinski2-2/+2
NFD ABI 0.5 is equivalent to NFD ABI 3.0 but requires that the driver checks the APP id symbol and makes sure it can support given app. Most advanced apps will likely require control vNIC (ability to exchange control messages between the driver and app FW). Detailed app version checking and capability exchange is left to app-specific code. Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-06-07nfp: create control vNICs and wire up rx/txJakub Kicinski5-15/+177
When driver encounters an nfp_app which has a control message handler defined, allocate a control vNIC. This control channel will be used to exchange data with the application FW such as flow table programming, statistics and global datapath control.

2017-06-07nfp: allow non-equal distribution of IRQsJakub Kicinski1-1/+2

2017-06-07nfp: slice the netdev spawning functionJakub Kicinski1-25/+37
We want to be able to create a special vNIC for control messages. This vNIC should be created before any netdev is registered to allow nfp_app logic to exchange messages with the FW app before any netdev is visible to user space. Unfortunately we can't enable IRQs until we know how many vNICs we will need to spawn. Divide the function which spawns netdevs for vNICs into three parts: - vNIC/memory allocation; - IRQ allocation; - netdev init and register. This will help us insert the initialization of the control channel after IRQ allocation but before netdev init and register.

2017-06-07nfp: don't clutter init code passing fw_ver aroundJakub Kicinski1-10/+7
Reading fw version from the BAR is trivial. Don't pass it around through layers of init functions, simply read it again where needed. This commit has the side effect of each vNIC having the exact NFD version from its own control memory, rather than all data vNICs assuming the version of the first one. This should not result in user-visible changes, though. Capabilities of data vNICs of trival apps are identical. Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S.

2017-06-07nfp: map all queue controllers at onceJakub Kicinski3-101/+28

2017-06-07nfp: split out the allocation part of openJakub Kicinski1-22/+35
Our open/close implementations have 3 stages: - allocation/freeing of ring resources, irqs etc., - device config, - device/stack enable (can't fail). Right now all of those stages are placed in separate functions, apart from allocation during open. Fix that. It will make it easier for us to allocate resources for netdev-less vNICs. Because we want to reuse allocation code in netdev-less vNICs leave the netif_set_real_num_[rt]x_queues() calls inside open.

Add phylib support for the Marvell Alaska X 10 Gigabit PHY (MV88X3310). This phy is able to operate at 10G, 1G, 100M and 10M speeds, and only supports Clause 45 accesses. The PHY appears (based on the vendor IDs) to be two different vendors IP, with each devad containing several instances. This PHY driver has only been tested with the RJ45 copper port, fiber port and a Marvell Armada 8040-based ethernet interface. It should be noted that to use the full range of speeds, MAC drivers need to also reconfigure the link mode as per phydev->interface, since the PHY automatically changes its interface mode depending on the negotiated speed.

2017-06-06net: stmmac: fix completely hung TX when using TSONiklas Cassel1-1/+1
stmmac_tso_allocator can fail to set the Last Descriptor bit on a descriptor that actually was the last descriptor. This happens when the buffer of the last descriptor ends up having a size of exactly TSO_MAX_BUFF_SIZE. When the IP eventually reaches the next last descriptor, which actually has the bit set, the DMA will hang. When the DMA hangs, we get a tx timeout, however, since stmmac does not do a complete reset of the IP in stmmac_tx_timeout, we end up in a state with completely hung TX.

Commit a47b70ea86bd ("ravb: unmap descriptors when freeing rings") has introduced the issue seen in [1] reproduced on H3ULCB board. Fix this by relocating the RX skb ringbuffer free operation, so that swiotlb page unmapping can be done first. Freeing of aligned TX buffers is not relevant to the issue seen in [1]. Still, reposition TX free calls as well, to have all kfree() operations performed consistently _after_ dma_unmap_*()/dma_free_*().

Bridgeport is a l2-specific feature, and we should write its capabilities to a debug entry. Signed-off-by: Julian Wiedmann <jwi@linux.vnet.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>

HiperSocket devices don't need the full IPv6 initialization, but we should still query the supported assists for logging purposes. Signed-off-by: Julian Wiedmann <jwi@linux.vnet.ibm.com> Acked-by: Ursula Braun <ubraun@linux.vnet.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-06-06s390/qeth: remove skb_is_nonlinear() check on IQDJulian Wiedmann1-7/+1
qeth doesn't advertise NETIF_F_SG for L3 IQDs. So trust the stack to not hand us any nonlinear skbs, and remove an always-true condition. With the fact that data_offset < 0 is no longer possible on IQDs, apply a small cleanup to subsequent code.

The "trap_id" is 9bits long. So far, this was not a problem since we used only traps with ids that fit into 8bits. But the ACL traps that are going to be introduced use the 9th bit.
