* bnxt_en: Implement missing tx timeout reset logic.Michael Chan2015-12-111-3/+13
| | | | | | | | | | | The reset logic calls bnxt_close_nic() and bnxt_open_nic() under rtnl_lock from bnxt_sp_task. BNXT_STATE_IN_SP_TASK must be cleared before calling bnxt_close_nic() to avoid deadlock. v2: Fixed white space error. Thanks Dave.

* bnxt_en: Don't cancel sp_task from bnxt_close_nic().Michael Chan2015-12-112-2/+12
| | | | | | | | | | | | | When implementing driver reset from tx_timeout in the next patch, bnxt_close_nic() will be called from the sp_task workqueue. Calling cancel_work() on sp_task will hang the workqueue. Instead, set a new bit BNXT_STATE_IN_SP_TASK when bnxt_sp_task() is running. bnxt_close_nic() will wait for BNXT_STATE_IN_SP_TASK to clear before proceeding.

* net: ezchip: fix address space confusion in nps_enet.cArnd Bergmann2015-12-081-21/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The nps_enet driver happily mixes virtual, physical and __iomem addresses, which are all different depending on the architecture and configuration. That causes a warning when building the code on ARM with LPAE mode enabled: drivers/net/ethernet/ezchip/nps_enet.c: In function 'nps_enet_send_frame': drivers/net/ethernet/ezchip/nps_enet.c:370:13: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] but will also fail to work for other reasons. In this patch, I'm trying to change the code to use only normal kernel pointers, which I assume is what the author actually meant: * For reading or writing a 32-bit word that may be unaligned when an SKB contains unaligned data, I'm using get_unaligned/put_unaligned() rather than memcpy_fromio/toio. * For converting a u8 pointer to a u32 pointer, I use a cast rather than the incorrect virt_to_phys. * For copying a couple of bytes from one place to another while respecting alignment, I use memcpy instead of memcpy_toio.

* net: thunderx: Correctly distinguish between VF and LMAC countPavel Fedin2015-12-081-21/+18
| | | | | | | | | | | | | | | | | | | | | Commit bc69fdfc6c13 ("net: thunderx: Enable BGX LMAC's RX/TX only after VF is up") introduces lmac_cnt member and starts verifying VF number against it. This is plain wrong, and works only because currently we have hardcoded 1:1 mapping between VFs and LMACs, and in this case num_vf_en and lmac_cnt are always equal. However in future this may change, and the code will badly misbehave. The worst consequence of this is failure to deliver link status messages, causing VFs to go defunct because since commit 0b72a9a1060e ("net: thunderx: Switchon carrier only upon interface link up") VF will not fully bring itself up without it. This patch fixes the potential problem by doing VF number checks against the num_vf_en. Since lmac_cnt is not used anywhere else, it is removed. Additionally some duplicated code is factored out into nic_enable_vf() Signed-off-by: Pavel Fedin <p.fedin@samsung.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* qed: Correct slowpath interrupt schemeSudarsana Kalluru2015-12-074-52/+55
| | | | | | | | | | | | | | | | | When using INTa, ISR might be called before device is configured for INTa [E.g., due to other device asserting the shared interrupt line], in which case the ISR would read the SISR registers that shouldn't be read unless HW is already configured for INTa. This might break interrupts later on. There's also an MSI-X issue due to this difference, although it's mostly theoretical. This patch changes the initialization order, calling request_irq() for the slowpath interrupt only after the chip is configured for working in the preferred interrupt mode.

* qed: fix handling of concurrent ramrods.Tomer Tayar2015-12-072-17/+54
| | | | | | | | | | | | | | | | | | | | | Concurrent non-blocking slowpath ramrods can be completed out-of-order on the completion chain. Recycling completed elements, while previously sent elements are still completion pending, can lead to overriding of active elements on the chain. Furthermore, sending pending slowpath ramrods currently lacks the update of the chain element physical pointer. This patch: * Ensures that ramrods are sent to the FW with consecutive echo values. * Handles out-of-order completions by freeing only first successive completed entries. * Updates the chain element physical pointer when copying a pending element into a free element for sending.

| | | | | | | | | | | | | | | | There is a memleak when suspend/resume this driver version. Currently the stmmac, during resume step, reallocates all the resources but they are not released when suspend. The patch is not to release these resources but the logic has been changed. In fact, it is not necessary to free and reallocate all from scratch because the memory data will be always preserved. As final solution, the patch just reinit the descriptors and the rx/tx pointers only when resume. Tested done on STi boxes.

| * ixgbe: Reset interface after enabling SR-IOVAlexander Duyck2015-12-031-0/+3

Specifically the MAC address was enabled for both VF 0 and the PF. This resulted in some odd behaviors such as VF 0 receiving a copy of the PFs traffic, which in turn enables the ability for VF 0 to spoof the PF. A workaround for this issue appears to be to bring up the interface first and then enable SR-IOV as this way the reset is then triggered in the existing code. In order to correct this I have added a change to ixgbe_setup_tc where if the interface is down we still will at least call ixgbe_reset so that the MAC addresses for the device are reset to the correct pools. Steps to reproduce issue: modprobe ixgbe echo 7 > /sys/bus/pci/devices/0000\:01\:00.1/sriov_numvfs ifconfig enp1s0f1 up ethregs -s 1:00.1 | grep MPSAR | grep -v 00000000 Result: MPSAR[0] 00000081 MPSAR[254] 00000001 Expected Result, behavior after patch: MPSAR[0] 00000080 MPSAR[254] 00000080 Signed-off-by: Alexander Duyck <aduyck@mirantis.com> Tested-by: Darin Miller <darin.j.miller@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the driver is used on an ARM platform with SPARSE_IRQ defined, semantics of NR_IRQS is different (minimal value of virtual irqs) and by default it is set to 16, see arch/arm/include/asm/irq.h. This value may be less than the actual number of virtual irqs, which may break the driver initialization. The check removal allows to use the driver on such a platform, and, if irq controller driver works correctly, the check is not needed on legacy platforms.

| * net: mvneta: enable setting custom TX IP checksum limitMarcin Wojtas2015-12-021-2/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since Armada 38x SoC can support IP checksum for jumbo frames only on a single port, it means that this feature should be enabled per-port, rather than for the whole SoC. This patch enables setting custom TX IP checksum limit by adding new optional property to the mvneta device tree node. If not used, by default 1600B is set for "marvell,armada-370-neta" and 9800B for other strings, which ensures backward compatibility. Binding documentation is updated accordingly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the actual RX processing, there is same error path for both descriptor ring refilling and building skb fails. This is not correct, because after successful refill, the ring is already updated with newly allocated buffer. Then, in case of build_skb() fail, hitherto code left the original buffer unmapped. This patch fixes above situation by swapping error check of skb build with DMA-unmap of original buffer.

While testing on a network environment with not standard MTU (e.g. 3000), a panic occurred if an incoming packet had a length greater than rx skb buffer size. This is because the HW is programmed to copy, from the DMA, an Jumbo frame and the Sw must check if the allocated buffer is enough to store the frame.
