2013-07-02alx: fix MAC address alignment problemJohannes Berg1-4/+4
In two places, parts of MAC addresses are used as u32/u16 values. This can cause alignment problems, use put_unaligned and get_unaligned to fix this.

2013-07-02net/mlx4_core: Dynamic VST to VST vlan/qos changesJack Morgenstein4-10/+282
Within VST mode, enable modifying the vlan and/or qos for a VF without requiring unbind/rebind. This requires firmware which supports the UPDATE_QP command. (If the command is not available, we fall back to requiring unbind/bind to activate these changes). To avoid race conditions with modify-qp on QPs that are affected by update-qp, this operation is performed on the comm_wq. If the update operation succeeds for all the necessary QPs, a vlan_unregister is performed for the abandoned vlan id.

2013-06-26arc_emac: fix compile-time errors & warnings on PPC64Alexey Brodkin1-26/+39
As reported by "kbuild test robot" there were some errors and warnings on attempt to build kernel with "make ARCH=powerpc allmodconfig". And this patch addresses both errors and warnings. Below is a list of introduced changes: 1. Fix compile-time errors (misspellings in "dma_unmap_single") on PPC. 2. Use DMA address instead of "skb->data" as a pointer to data buffer. This fixed warnings on pointer to int conversion on 64-bit systems. 3. Re-implemented initial allocation of Rx buffers in "arc_emac_open" in the same way they're re-allocated during operation (receiving packets). So once again DMA address could be used instead of "skb->data". 4. Explicitly use EMAC_BUFFER_SIZE for Rx buffers allocation.

2013-06-26mlx4: allow order-0 memory allocations in RX pathEric Dumazet2-86/+95
Signed-off-by: Eric Dumazet <edumazet@google.com> mlx4 exclusively uses order-2 allocations in RX path, which are likely to fail under memory pressure. We therefore drop frames more than needed. This patch tries order-3, order-2, order-1 and finally order-0 allocations to keep good performance, yet allow allocations if/when memory gets fragmented. By using larger pages, and avoiding unnecessary get_page()/put_page() on compound pages, this patch improves performance as well, lowering false sharing on struct page. Also use GFP_KERNEL allocations in initialization path, as allocating 12 MB (390 order-3 pages) can easily fail with GFP_ATOMIC.

Enable accelerated RFS for VLAN-tagged flows, from Andy Lutomirski. 3. Improve performance for non-TCP (and particularly UDP) traffic, which regressed in 3.10 when we switched to always allocating paged RX buffers. Partly by Jon Cooper. 4. Some minor bug fixes to IOMMU detection, timestamping capabilities, and IRQ cleanup on the probe failure path. I've dropped the RX skb cache, which improved some benchmarks but perhaps needs some reworking to be more generally useful. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2013-06-24sfc: Fix IRQ cleanup in case of a probe failureBen Hutchings2-38/+40
The lifetime of an irq_cpu_rmap is odd: we have to allocate it before installing IRQ handlers and free it before removing the IRQ handlers. As a result of this asymmetry, it was omitted from some failure paths. On another failure path, we could try to remove IRQ handlers we had not yet installed. Move the irq_cpu_rmap allocation and freeing alongside IRQ handler installation and removal, in efx_nic_{init,fini}_interrupts(). Count the number of IRQ handlers successfully installed and only remove those on the failure path. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2013-06-24sfc: Do not pass non-TCP packets into GRO codeBen Hutchings1-1/+1
GRO can handle non-TCP packets and pass them up without coalescing, but it has to do some extra work to parse the packet which we can bypass using the hardware parse result. (This condition yields a false negative for TCP/IPv6 packets received by Falcon, but its performance is already poor in that case due to lack of checksum offload.)
