Made in-memory rcvhdrq tail update be in dma_alloc'ed memory, not random user or special kernel (needed for ppc, also "just the right thing to do"). Some cleanups to make unexpected link transitions less likely to produce complaints about packet errors, and also to not leave SMA packets stuck and unable to go out. A few other random debug and comment cleanups. Always init rcvhdrq head/tail registers to 0, to avoid race conditions (should have been that way some time ago). Signed-off-by:

These limits are somewhat artificial in that we don't actually have any device limits. However, the verbs layer expects that such limits exist and are enforced, so we make up arbitrary (but sensible) limits. Signed-off-by:

There is no longer a /dev/ipath_diag file; instead, there's /dev/ipath_diag0, 1, etc. It's still not possible to have diags run on more than one unit at a time, but that's easy to fix at some point. Signed-off-by:

IRQ_PER_CPU is a bit in the struct irq_desc "status" field, not in the struct irqaction "flags", so the previous code checked the wrong bit. SA_PERCPU_IRQ is only used by drivers/char/mmtimer.c for SGI ia64 boxes. Signed-off-by:

lock_queue was getting called essentially twice in a row and was continually incrementing the mm_count ref count, thus causing a memory leak. Dinakar Guniguntala provided a proper fix for the problem that simply grabs the spinlock for the hash bucket queue rather than calling lock_queue. The second time we do a queue_lock in futex_lock_pi, we really only need to take the hash bucket lock. Signed-off-by:

This patch adds GSO support for IPv6 and TCPv6. This is based on a patch by Ananda Raju <Ananda.Raju@neterion.com>. His original description is: This patch enables TSO over IPv6. Currently Linux network stacks restricts TSO over IPv6 by clearing of the NETIF_F_TSO bit from "dev->features". This patch will remove this restriction. This patch will introduce a new flag NETIF_F_TSO6 which will be used to check whether device supports TSO over IPv6. If device support TSO over IPv6 then we don't clear of NETIF_F_TSO and which will make the TCP layer to create TSO packets. Any device supporting TSO over IPv6 will set NETIF_F_TSO6 flag in "dev->features" along with NETIF_F_TSO. In case when user disables TSO using ethtool, NETIF_F_TSO will get cleared from "dev->features". So even if we have NETIF_F_TSO6 we don't get TSO packets created by TCP layer. SKB_GSO_TCPV4 renamed to SKB_GSO_TCP to make it generic GSO packet. SKB_GSO_UDPV4 renamed to SKB_GSO_UDP as UFO is not a IPv4 feature. UFO is supported over IPv6 also The following table shows there is significant improvement in throughput with normal frames and CPU usage for both normal and jumbo. -------------------------------------------------- | | 1500 | 9600 | | ------------------|-------------------| | | thru CPU | thru CPU | -------------------------------------------------- | TSO OFF | 2.00 5.5% id | 5.66 20.0% id | -------------------------------------------------- | TSO ON | 2.63 78.0 id | 5.67 39.0% id | -------------------------------------------------- Signed-off-by:

This patch generalises the TSO-specific bits from sk_setup_caps by adding the sk_gso_type member to struct sock. This makes sk_setup_caps generic so that it can be used by TCPv6 or UFO. The only catch is that whoever uses this must provide a GSO implementation for their protocol which I think is a fair deal :) For now UFO continues to live without a GSO implementation which is OK since it doesn't use the sock caps field at the moment.
