Make use of the newly-added generic MDIO clause 45 support and remove redundant definitions. Add an 'efx_' prefix to the remaining driver-specific MDIO functions and remove arguments which are redundant with efx->mdio.prtad. Signed-off-by:

Ben Hutchings authored
IEEE 802.3 clause 45 specifies the MDIO interface and registers for use in 10G and other PHYs, similar to the MII management interface. PHYs may have up to 32 MMDs corresponding to different sub-layers and functions, each with up to 65536 registers. These are addressed by PRTAD (similar to the MII PHY address) and DEVAD. Define a mapping for specifying PRTAD and DEVAD through the existing MII ioctls. Signed-off-by:

These two memory barriers in performance-critical paths are not needed on x86. Even if some other architecture does buffer PCI I/O space writes, the existing memory-mapped I/O barriers are unlikely to be what is needed. Signed-off-by:

We were calling pci_enable_wake() twice in a row for both D3_hot and D3_cold. This replaces those calls with a call to pci_wake_from_d3() to avoid issues with PCI PM vs ordering constraints. Signed-off-by:

cacheable_memzero() is completely overkill for the clearing out the FCB block which is only 8-bytes. The compiler should easily optimize this with memset. Additionally, cacheable_memzero() only exists on ppc32 and thus breaks builds of gianfar on ppc64. Signed-off-by:

netif_tx_queue_stopped(txq) is most of the time false. Yet its cost is very expensive on SMP. static inline int netif_tx_queue_stopped(const struct netdev_queue *dev_queue) { return test_bit(__QUEUE_STATE_XOFF, &dev_queue->state); } I saw this on oprofile hunting and bnx2 driver bnx2_tx_int(). We probably should split "struct netdev_queue" in two parts, one being read mostly. __netif_tx_lock() touches _xmit_lock & xmit_lock_owner, these deserve a separate cache line.

This patch enables hardware receive side coalescing for 82599 hardware. 82599 can merge multiple frames from the same TCP/IP flow into a single structure that can span one ore more descriptors. The accumulated data is arranged similar to how jumbo frames are arranged with the exception that other packets can be interlaced inbetween. To overcome this issue a next pointer is included in the written back descriptor which indicates the next descriptor in the writeback sequence. This feature sets the NETIF_F_LRO flag and clearing it via the ethtool set flags operation will also disable hardware RSC. Signed-off-by:

Originally from: Vlad Yasevich <vladislav.yasevich@hp.com> This patch, both the driver portion and the sctp code was modified by Jesse Brandeburg and is Copyright(c) 2009 Intel Corporation. Thanks go to Vlad for starting this work. Intel 82576 chipset supports SCTP checksum offloading. This patch enables this functionality in the driver. A new NETIF feature is introduced for SCTP checksum offload. If the driver supports CRC32c checksum, it can set this feature flag. The hardware can offload both transmit and receive. Signed-off-by:

Both of these drivers do a check to verify ip_summed is set to CHECKSUM_UNNECESSARY prior to passing the packet to GRO. GRO itself already does such a check so it is redundant and can be removed as this will likely cause out of order issues when receiving a packet that didn't pass checksum validation. Signed-off-by:

This is V2 of the smsc911x fifo byteswap patch. The smsc911x hardware supports both big and little and endian hardware configurations, and the linux smsc911x driver currently detects word order. For correct operation on big endian platforms lacking swapped byte lanes the following patch is needed. Only fifo data is swapped, register data does not require any swapping. Signed-off-by:

Herbert Xu authored
The skb_gro_* code fails to handle the case where a header starts in the linear area but ends in the frags area. Since the goal of skb_gro_* is to optimise the case of completely non-linear packets, we can simply bail out if we have anything in the linear area. Signed-off-by:

>From now on FW will be downloaded from the binary file using request_firmware. There will be different files for every supported chip. Currently 57710 (e1) and 57711 (e1h). File names have the following format: bnx2x-<chip version>-<FW version>.fw. ihex versions of current FW files are submitted in the next patch. Each binary file has a header in the following format: struct bnx2x_fw_file_section { __be32 len; __be32 offset; } struct bnx2x_fw_file_hdr { struct bnx2x_fw_file_section init_ops; struct bnx2x_fw_file_section init_ops_offsets; struct bnx2x_fw_file_section init_data; struct bnx2x_fw_file_section tsem_int_table_data; struct bnx2x_fw_file_section tsem_pram_data; struct bnx2x_fw_file_section usem_int_table_data; struct bnx2x_fw_file_section usem_pram_data; struct bnx2x_fw_file_section csem_int_table_data; struct bnx2x_fw_file_section csem_pram_data; struct bnx2x_fw_file_section xsem_int_table_data; struct bnx2x_fw_file_section xsem_pram_data; struct bnx2x_fw_file_section fw_version; } Each bnx2x_fw_file_section contains the length and the offset of the appropriate section in the binary file. Values are stored in the big endian format. Data types of arrays: init_data __be32 init_ops_offsets __be16 XXsem_pram_data u8 XXsem_int_table_data u8 init_ops struct raw_op { u8 op; __be24 offset; __be32 data; } fw_version u8 >From now boundaries of a specific initialization stage are stored in init_ops_offsets array instead of being defined by separate macroes. The index in init_ops_offsets is calculated by BLOCK_OPS_IDX macro: #define BLOCK_OPS_IDX(block, stage, end) \ (2*(((block)*STAGE_IDX_MAX) + (stage)) + (end)) Security: In addition to sanity check of array boundaries bnx2x will check a FW version. Additional checks might be added in the future. Signed-off-by: -

When creating a certain types of VPN, NetworkManager will first attempt to find an available tun device by iterating through 'vpn%d' until it finds one that isn't already busy. Then it'll set that to be persistent and owned by the otherwise unprivileged user that the VPN dæmon itself runs as. There's a race condition here -- during the period where the vpn%d device is created and we're waiting for the VPN dæmon to actually connect and use it, if we try to create _another_ device we could end up re-using the same one -- because trying to open it again doesn't get -EBUSY as it would while it's _actually_ busy. So solve this, we add an IFF_TUN_EXCL flag which causes tun_set_iff() to fail if it would be opening an existing persistent tundevice -- so that we can make sure we're getting an entirely _new_ device.

When I initially implemented this protocol, I disregarded the use of netlink attribute headers, thinking for my purposes they weren't needed. I've come to find out that, as I'm starting to work with sending down messages with associated data (like config messages), the kernel code spits out warnings about trailing data in a netlink skb that doesn't have an associated header on it. As such, I'm going to start including attribute headers in my netlink transaction, and so for completeness, I should likely include them on messages bound from the kernel to user space. This patch adds that header to the kernel, and bumps the protocol version accordingly Signed-off-by:

82598 and 82599 do not support SFP 1G modules. Instead of allowing the driver to load, but never get link, rejecting the module and displaying a useful message is more preferrable. The framework for displaying the failure message already exists, now we just need to detect and reject the SFP modules. Signed-off-by:

The igb driver was switching between adapter->itr containing the EITR value and the number of interrupts per second. This resulted in high latencies being seen after brining the interface down and then back up. To resolve the issue the itr value will now only contain the value that should be programmed into EITR.

Pointed out by Sean E. Millichamp. Quote from Documentation/networking/bonding.txt: "Note that when a bonding interface has no active links, the driver will immediately reuse the first link that goes up, even if the updelay parameter has been specified (the updelay is ignored in this case). If there are slave interfaces waiting for the updelay timeout to expire, the interface that first went into that state will be immediately reused. This reduces down time of the network if the value of updelay has been overestimated, and since this occurs only in cases with no connectivity, there is no additional penalty for ignoring the updelay." This patch actually changes the behaviour in this way. Signed-off-by:
