skb allocation / cosumption tracer - Add consumption tracepoint This patch adds a tracepoint to skb_copy_datagram_iovec, which is called each time a userspace process copies a frame from a socket receive queue to a user space buffer. It allows us to hook in and examine each sk_buff that the system receives on a per-socket bases, and can be use to compile a list of which skb's were received by which processes. Signed-off-by:

This also avoids a potential buffer overflow in case the very first receive descriptor fails to allocate, as an index of -1 would be used afterwards. Kudos to Roel Kluin for pointing this out and providing an initial patch. Signed-off-by:

The macro DRV_NAME contains "korina", the field dev->name points to the actual interface name. So messages were formerly prefixed with 'korinaeth2:' (on my system). Signed-off-by:

This patch adds a 'hairpin' (also called 'reflective relay') mode port configuration to the Linux Ethernet bridge kernel module. A bridge supporting hairpin forwarding mode can send frames back out through the port the frame was received on. Hairpin mode is required to support basic VEPA (Virtual Ethernet Port Aggregator) capabilities. You can find additional information on VEPA here: http://tech.groups.yahoo.com/group/evb/ http://www.ieee802.org/1/files/public/docs2009/new-hudson-vepa_seminar-20090514d.pdf http://www.internet2.edu/presentations/jt2009jul/20090719-congdon.pdf An additional patch 'bridge-utils: Add 'hairpin' port forwarding mode' is provided to allow configuring hairpin mode from userspace tools.

If an interface has multiple addresses, the current message for DAD failure isn't really helpful, so this patch adds the address itself to the printk. Signed-off-by:

Without this check, when running out of memory, we will see PSOD's in bnx2x_init_fill() when doing a memset(). This is because at that time, bp->gunzip_buf is not pointing to a valid allocated space. Signed-off-by:

Moved the dmae_command from the heap to the stack. This will save 56 bytes per bnx2x structure. As a side benefit, we can also reduce the time the dmae_mutex is held. This is because do we not need to hold this mutex when setting up the dmae command. The memory where is dmae command is stored is not a shared resource and doesn not need to be protected.

Move printing of version from probe to the init function Rather then checking if this is the first module probe call to print the version of the driver only once, the statement is moved to the init function of the module where init is only called once Signed-off-by:

The functions bnx2x_get_pcie_width() and bnx2x_get_pcie_speed() were combined into bnx2x_get_pcie_width_speed() so that there is only 1 PCI read to PCICFG_OFFSET + PCICFG_LINK_CONTROL rather then 2 reads. Signed-off-by:

When a given ring is running out of space, the FW can send pause towards the network. When working with multi-queues, when one queue is getting out of space it can block all other queues. The preferred scheme is to send pause frames only when running out of the shared internal chip buffers and if a given queue cannot place a packet on the host, it will drop it. Since some users might want to work in drop-less mode, allowing changing the behavior as a module parameter. Signed-off-by:

There are 3 operations that the driver needs to support to allow applications to access the PHY FW (on top of the MDC/MDIO access). Since those are essentially nvram access commands, adding them to the ethtool -E interface. Signed-off-by:

The BCM8481 does not generate LASI interrupt for 10M, 100M and 1G link, so we are using LED4 output as the interrupt input to the 57711. This requires some adaptation in the link interrupt routines Signed-off-by:
