  • 36909ea43   net: Add alloc_netdev_mqs function ... Browse Code »

    Added alloc_netdev_mqs function which allows the number of transmit and
    receive queues to be specified independenty. alloc_netdev_mq was
    changed to a macro to call the new function. Also added
    alloc_etherdev_mqs with same purpose.

  • 40d0802b3   gro: __napi_gro_receive() optimizations ... Browse Code »

    compare_ether_header() can have a special implementation on 64 bit
    arches if CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS is defined.

    __napi_gro_receive() and vlan_gro_common() can avoid a conditional
    branch to perform device match.

    On x86_64, __napi_gro_receive() has now 38 instructions instead of 53

    As gcc-4.4.3 still choose to not inline it, add inline keyword to this
    performance critical function.

  • c1f79426e   sysfs: add attribute to indicate hw address assignment type ... Browse Code »

    Add addr_assign_type to struct net_device and expose it via sysfs.
    This new attribute has the purpose of giving user-space the ability to
    distinguish between different assignment types of MAC addresses.

    For example user-space can treat NICs with randomly generated MAC
    addresses differently than NICs that have permanent (locally assigned)
    MAC addresses.
    For the former udev could write a persistent net rule by matching the
    device path instead of the MAC address.
    There's also the case of devices that 'steal' MAC addresses from slave
    devices. In which it is also be beneficial for user-space to be aware
    of the fact.

    This patch also introduces a helper function to assist adoption of
    drivers that generate MAC addresses randomly.

  • f001fde5e   net: introduce a list of device addresses dev_addr_list (v6) ... Browse Code »

    v5 -> v6 (current):
    -removed so far unused static functions
    -corrected dev_addr_del_multiple to call del instead of add

    v4 -> v5:
    -added device address type (suggested by davem)
    -removed refcounting (better to have simplier code then safe potentially few
    bytes)

    v3 -> v4:
    -changed kzalloc to kmalloc in __hw_addr_add_ii()
    -ASSERT_RTNL() avoided in dev_addr_flush() and dev_addr_init()

    v2 -> v3:
    -removed unnecessary rcu read locking
    -moved dev_addr_flush() calling to ensure no null dereference of dev_addr

    v1 -> v2:
    -added forgotten ASSERT_RTNL to dev_addr_init and dev_addr_flush
    -removed unnecessary rcu_read locking in dev_addr_init
    -use compare_ether_addr_64bits instead of compare_ether_addr
    -use L1_CACHE_BYTES as size for allocating struct netdev_hw_addr
    -use call_rcu instead of rcu_synchronize
    -moved is_etherdev_addr into __KERNEL__ ifdef

    This patch introduces a new list in struct net_device and brings a set of
    functions to handle the work with device address list. The list is a replacement
    for the original dev_addr field and because in some situations there is need to
    carry several device addresses with the net device. To be backward compatible,
    dev_addr is made to point to the first member of the list so original drivers
    sees no difference.

  • aa4b9f533   gro: Optimise Ethernet header comparison ... Browse Code »

    This patch optimises the Ethernet header comparison to use 2-byte
    and 4-byte xors instead of memcmp. In order to facilitate this,
    the actual comparison is now carried out by the callers of the
    shared dev_gro_receive function.

    This has a significant impact when receiving 1500B packets through
    10GbE.

  • 1f87e235e   eth: Declare an optimized compare_ether_addr_64bits() function ... Browse Code »

    Linus mentioned we could try to perform long word operations, even
    on potentially unaligned addresses, on x86 at least. David mentioned
    the HAVE_EFFICIENT_UNALIGNED_ACCESS test to handle this on all
    arches that have efficient unailgned accesses.

    I tried this idea and got nice assembly on 32 bits:

    158: 33 82 38 01 00 00 xor 0x138(%edx),%eax
    15e: 33 8a 34 01 00 00 xor 0x134(%edx),%ecx
    164: c1 e0 10 shl $0x10,%eax
    167: 09 c1 or %eax,%ecx
    169: 74 0b je 176

    And very nice assembly on 64 bits of course (one xor, one shl)

    Nice oprofile improvement in eth_type_trans(), 0.17 % instead of 0.41 %,
    expected since we remove 8 instructions on a fast path.

    This patch implements a compare_ether_addr_64bits() function, that
    uses the CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS ifdef to efficiently
    perform the 6 bytes comparison on all capable arches.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
