On A0 revision of 57765 asic rev devices, the bootcode will perform some hardware operations, after the magic signature is presented, that will collide with setup operations performed by the driver. The best way to avoid the contention is to have the driver delay an additional 10 milliseconds. B0 revisions of the chip will make this workaround unnecessary. Signed-off-by:

The previous patch changed the code so that new rx buffer submissions to the hardware stall if a new submission would overwrite data needed by an unserviced rx packet. On very busy 5717 and 57765 asic rev devices, there is a corner case where the hardware will fail to assert an MSI-X interrupt for rx traffic. If that vector's interrupt never has another reason to assert, any rx buffers held will never be serviced. If the buffers are never serviced and the hardware consumes all the available rx packets for other rx rings, deadlock will result. The most reliable and least intrusive way to work around the problem is to detect the case where new submissions would overwrite existing data and force all rx interrupt vectors to fire.

When operating in RSS mode, it is possible for one rx return ring to submit enough rx buffers back to the hardware such that it inadvertently overwrites data needed by another rx return ring. This patch addresses the problem by looking for non-NULL skb pointers in the rx_[std|jmb]_buffers rings that parallel the rx producer rings. Signed-off-by:

RSS ring 1 is responsible for submitting new rx buffers to the hardware on behalf of all the other RSS rx return rings. Up until now this ring submitted its new rx buffers to the producer ring directly. The following patch will require that this ring have a place to put backlogged rx packets. As a consequence, it can no longer submit new buffers to the producer ring. This patch adds code to allocate an extra shadow producer ring for this RSS ring and adds RSS ring 1 to the list of rings needing buffer transfers. Signed-off-by:

The variable 'copied' is used in udp_recvmsg() to emphasize that the passed 'len' is adjusted to fit the actual datagram length. But the same can be done by adjusting 'len' directly. This patch thus removes the indirection. Signed-off-by:

DCCP is datagram-oriented but lacks UDP's support for MSG_TRUNC as defined in recvmsg(2)/recv(2). Hence the following 'Hello world\0' receiver len = recv(fd, buf, 10, MSG_PEEK | MSG_TRUNC); wrongly (always) returns 10, while in UDP it returns 12 as expected. This patch adds the missing MSG_TRUNC support to recvmsg(). Signed-off-by:

Rewrite sky2_reset to work with interrupts disabled and avoid freeing and reallocing memory. The old code used sky2_down and sky2_up to implement sky2_reset, which meant interrupts could not be disabled, and the transmit and receive ring buffers would be free'd and reallocated. To avoid the interrupt handler waking the transmit queue while we're doing a reset, it's better to have interrupts and NAPI polls disabled. Note: Modified Mike's patch to do IRQ disable in sky2_down before calling sky2_hw_down - Stephen Signed-off-by:

Allocate everything in one place so there's a single point of failure in sky2_up, and sky2_rx_start can no longer fail. Don't leave the hardware in a partially initialized state in the case rx ring allocation fails. As with the old code, the rx ring still needs to be fully allocated for sky2_up to succeed.

These netdev_printk routines take a struct net_device * and emit dev_printk logging messages adding "%s: " ... netdev->dev.parent to the dev_printk format and arguments.

Permanent IPV6 addresses should not be removed when the link is set to admin down, only when device is removed. When link is lost permanent addresses should be marked as tentative so that when link comes back they are subject to duplicate address detection (if DAD was enabled for that address). Other routing systems keep manually configured IPv6 addresses when link is set down. Signed-off-by:
