This patch introduces a new knob ndisc_notify. If enabled, the kernel will transmit an unsolicited neighbour advertisement on link-layer address change to update the neighbour tables of the corresponding hosts more quickly. This is the equivalent to arp_notify in ipv4 world. Signed-off-by:

This change is meant to both improve the performance and reduce the size of igb_tx_map. To do this I have expanded the work done in the main loop by pushing first into tx_buffer. This allows us to pull in the dma_mapping_error check, the tx_buffer value assignment, and the initial DMA value assignment to the Tx descriptor. The net result is that the function reduces in size by a little over a 100 bytes and is about 1% or 2% faster. Signed-off-by:

This change is meant to improve the efficiency of the Tx flags in igb by aligning them with the values that will later be written into either the cmd_type or olinfo. By doing this we are able to reduce most of these functions to either just a simple shift followed by an or in the case of cmd_type, or an and followed by an or in the case of olinfo. In order to avoid type conversion errors I also adjusted the locations where we were switching between CPU and little endian. Signed-off-by:

This change is meant to reduce the overhead for workloads that are not using either TSO or checksum offloads. Most of the time the compiler should jump ahead after failing this check to the VLAN check since in the igb_tx_csum call we start with that check as well. Signed-off-by:

napi_gro_receive shouldn't be called from netpoll context. Doing so was causing kernel panics when jumbo frames larger than 2K were set.

The way the code was previously written it was causing DCA to prefetch the entire packet into the cache when it was enabled. That is excessive as we only really need the headers. We are now prefetching the headers via software so doing this from DCA would be redundant anyway. So clear the bit that was causing us to prefetch the packet data and instead only use DCA for the descriptor rings. Signed-off-by:

If a gianfar ethernet device is down prior to hibernating a system, it will no longer be present upon system restore. For example: ~# ifconfig eth0 down ~# echo disk > /sys/power/state <trigger a restore from hibernation> ~# ifconfig eth0 up SIOCSIFFLAGS: No such device This happens because the restore function bails out early upon finding devices that were not up at hibernation. In doing so, it never gets to the netif_device_attach call at the end of the restore function. Adding the netif_device_attach as done here also makes the gfar_restore code consistent with what is done in the gfar_resume code. Cc: Claudiu Manoil <claudiu.manoil@freescale.com> Signed-off-by:

Should gfar_init_bds() return with -ENOMEM inside gfar_alloc_skb_resources(), free_skb_resources() will be called twice in a row on the "cleanup" path, leading to duplicate kfree() calls for rx_|tx_queue->rx_|tx_skbuff resulting in segmentation fault. This patch prevents the segmentation fault to happen in the future (rx_|tx_sbkbuff set to NULL), and corrects the error path handling for gfar_init_bds().

when something goes wrong, a flood of these messages can be generated by usbnet (thousands per second). This doesn't generally *help* the condition so this patch ratelimits the rate of their generation. There's an underlying problem in usbnet's kevent deferral mechanism which needs fixing, specifically that events *can* get dropped and not handled. This patch doesn't address this, but just mitigates fallout caused by the current implemention. Signed-off-by:
