This change is meant to address possible race conditions from the status and error bits on the RX descriptors being re-read by multiple functions in the RX cleanup path. To resolve this I have added code that will pass the staterr value to those functions. Signed-off-by:

This change moves work_limit, total_packets, and total_bytes into the ring container struct of the q_vector. The advantage of this is that it should reduce the size of memory used in the event of multiple rings being assigned to a single q_vector. In addition it should help to reduce the total workload for calculating itr since now total_packets and total_bytes will be the total work done of the interrupt instead of for the ring.

This patch adds support for a ring container structure to be used within the q_vector. The basic idea is to provide a means of separating the RX and TX rings while maintaining a common structure for their containment. The advantage to this is that later we should be able to pass this structure to the update_itr functions without needing to pass individual rings. Signed-off-by:

The ixgbe_maybe_stop_tx function is only a few lines long and is called multiple times through the xmit hotpath. In order to streamline things it makes sense to just inline it. Signed-off-by:

This change is meant to update ATR so that it will use the recorded RX queue instead of the CPU in the case of routing. This change is meant to help ixgbe default behavior to more closely match that of the kernel. Signed-off-by:

On this chipset it is required to configure the MPHY block for loopback tests. If MPHY is not configured then all loopback tests will report failures. Signed-off-by:

Interrupts about link lost or rx sequence errors are not reported by the ce4100 hardware, leading to transitions from link UP to link DOWN never being reported. Signed-off-by:

This patch adds new information for the driver especially about its platform structure fields. Signed-off-by:

Prior to this change, most PHY configuration parameters were passed into the STMMAC device as a separate PHY device. As well as being unusual, this made it difficult to make changes to the MAC/PHY relationship. This patch moves all the PHY parameters into the MAC configuration structure, mainly as a separate structure. This allows us to completely ignore the MDIO bus attached to a stmmac if desired, and not create the PHY bus. It also allows the stmmac driver to use a different PHY from the one it is connected to, for example a fixed PHY or bit banging PHY. Also derive the stmmac/PHY connection type (MII/RMII etc) from the mode can be passed into <platf>_configure_ethernet. STLinux kernel at git://git.stlinux.com/stm/linux-sh4-2.6.32.y.git provides several examples how to use this new infrastructure (that actually is easier to maintain and clearer). Signed-off-by:

Some drivers (ab)use the ethtool_ops::get_regs operation to expose only a hardware revision ID. Commit a77f5db3 ('ethtool: Allocate register dump buffer with vmalloc()') had the side-effect of breaking these, as vmalloc() returns a null pointer for size=0 whereas kmalloc() did not. For backward-compatibility, allow zero-length dumps again. Reported-by:

This patch add the missing dma_unmap(). Which solved the critical issue of system freeze on heavy load. Michal Miroslaw's rejected patch: [PATCH v2 10/46] net: jme: convert to generic DMA API Pointed out the issue also, thank you Michal. But the fix was incorrect. It would unmap needed address when low memory. Got lots of feedback from End user and Gentoo Bugzilla. https://bugs.gentoo.org/show_bug.cgi?id=373109 Thank you all. :) Cc: stable@kernel.org Signed-off-by:

There are two problems: 1) "n" was allocated with alloc_skb() so we should free it with kfree_skb() instead of regular kfree(). 2) We return the freed pointer instead of NULL. Signed-off-by:
