The SELinux netfilter hooks just return NF_DROP if they drop a packet. We want to signal that a drop in this hook is a permanant fatal error and is not transient. If we do this the error will be passed back up the stack in some places and applications will get a faster interaction that something went wrong. Signed-off-by:

The current tcp_connect code completely ignores errors from sending an skb. This makes sense in many situations (like -ENOBUFFS) but I want to be able to immediately fail connections if they are denied by the SELinux netfilter hook. Netfilter does not normally return ECONNREFUSED when it drops a packet so we respect that error code as a final and fatal error that can not be recovered. Based-on-patch-by:

SELinux would like to pass certain fatal errors back up the stack. This patch implements the generic netfilter support for this functionality. Based-on-patch-by:

With enabling CONFIG_PCI_MSI, e1000e could work in MSI/MSI-X IRQ mode, and netpoll controller didn't deal with those IRQ modes on e1000e. This patch add the handling MSI/MSI-X IRQ modes to netpoll controller, so that netconsole could work with those IRQ modes. Signed-off-by:

The driver can fail initializing the hardware when manageability firmware is performing concurrent MDIO operations because the hardware semaphore scheme to prevent concurrent operations between software and firmware is incorrect for 82574/82583. Instead of using the SWSM register, the driver should be using the EXTCNF_CTRL register. A software mutex is also added to prevent simultaneous software threads from performing similar concurrent accesses. Signed-off-by:

SerDes Link detection on certain 82571 mezzanine cards can fail when the link is forced, the link partner does not recognize forced link and the link partner sends null code words. Detect the null code words and return to auto-negotiation state which causes the link partner to begin responding with valid code words. Within a reasonable interval the link will finally settle as forced by both partners. Signed-off-by:

The driver is calling netif_carrier_off and netif_tx_stop_all_queues before the netdevice is registered which causes an Oops. Move call to netif_carrier_off after the netdevice is registered and remove call to netif_tx_stop_all_queues because there aren't any TX queues yet. Signed-off-by:

I noticed ring variable was initialized before allocations, and that memory node management was a bit ugly. We also leak memory in case of ring allocations error. Signed-off-by:

When invalidating the DDP context is invalidated, the HW may not be done with the user buffer right away. In which case, we poll the FCBUFF register to check if the buffer valid bit is cleared or not, if not, we wait for max 100us that is guaranteed by the HW. Signed-off-by:

The hw automatically invalidates the context if DDP is successful or there is error detected. In case there is no error status available from the hw, initializing the per context error status to be 1 allows the DDP context to be still invalidated via the upper layer call to ddp_put().

The Tx hang logic has been known to detect false hangs when the device is receiving pause frames or has delayed processing for some other reason. This patch makes the logic more robust and resolves these known issues. The old logic checked to see if the device was paused by querying the HW then the hang logic was aborted if the device was currently paused. This check was racy because the device could have been in the pause state any time up to this check. The other operation of the hang logic is to verify the Tx ring is still advancing the old logic checked the EOP timestamp. This is not sufficient to determine the ring is not advancing but only infers that it may be moving slowly. Here we add logic to track the number of completed Tx descriptors and use the adapter stats to check if any pause frames have been received since the previous Tx hang check. This way we avoid racing with the HW register and do not detect false hangs if the ring is advancing slowly. This patch is primarily the work of Jesse Brandeburg. I clean it up some and fixed the PFC checking. Signed-off-by:

There are a number of places where we use the variable j to contain the register index of the ring. Instead of using such a non-descriptive variable name it is better that we name it reg_idx so that it is clear what the variable contains. Signed-off-by:

This change cleans up the use of rsc_count and changes it to a boolean since the actual numerical value is used nowhere in the Rx cleanup path. I am also moving the skb count into the RSC_CB path since it is much easier to track it there than when it is passed as a parameter to various function calls. Signed-off-by:
