Since multiple team instances are putting defined options into their option list, during register each option must be cloned before added into list. This resolves uncool memory corruptions when using multiple teams. Signed-off-by:

Lancer uses V1 version of TXQ create. This command needs interface id for TX queue creation. Rearrange code such that tx queue create is after interface create. As TXQ create is now called after MCC ring create use MCC instead of MBOX. Signed-off-by:

Only distinct use is checking if NETIF_F_NOCACHE_COPY should be enabled by default. The check heuristics is altered a bit here, so it hits other people than before. The default shouldn't be trusted for performance-critical cases anyway. For all other uses NETIF_F_NO_CSUM is equivalent to NETIF_F_HW_CSUM. Signed-off-by:

Define feature values by bit position instead of direct 2**i values and force the values to be of type netdev_features_t. Cleaned and extended from patch by Mahesh Bandewar <maheshb@google.com>: + added netdev_features_t casts + included bits under NETIF_F_GSO_MASK + moved feature #defines out of struct net_device definition Signed-off-by:

netstamp_needed seems a good candidate to jump_label conversion. This avoids 3 conditional branches per incoming packet in fast path. No measurable difference, given that these conditional branches are predicted on modern cpus. Only a small icache reduction, thanks to the unlikely() stuff. Signed-off-by:

Add a new .bus_name to virtio_config_ops then modify virtio_net to call through to it in an ethtool .get_drvinfo routine to report bus_info in ethtool -i output which is consistent with other emulated NICs and the output of lspci. Signed-off-by:

This patch adds phy reset functionality to mdio-gpio driver. Now mdio_gpio_platform_data has new member as function pointer which can be filled at the bsp level for a callback from phy infrastructure. Also the mdio-bitbang driver fills-in the reset function of mii_bus structure. Without this patch the bsp level code has to takecare of the reseting PHY's on the bus, which become bit hacky for every bsp and phy-infrastructure is ignored aswell. Signed-off-by:

The support for NLM_F_* flags at IPv6 routing requests. If NLM_F_CREATE flag is not defined for RTM_NEWROUTE request, warning is printed, but no error is returned. Instead new route is added. Later NLM_F_CREATE may be required for new route creation. Exception is when NLM_F_REPLACE flag is given without NLM_F_CREATE, and no matching route is found. In this case it should be safe to assume that the request issuer is familiar with NLM_F_* flags, and does really not want route to be created. Specifying NLM_F_REPLACE flag will now make the kernel to search for matching route, and replace it with new one. If no route is found and NLM_F_CREATE is specified as well, then new route is created. Also, specifying NLM_F_EXCL will yield returning of error if matching route is found.

bnx2x uses following formula to compute its rx_buf_sz : dev->mtu + 2*L1_CACHE_BYTES + 14 + 8 + 8 + 2 Then core network adds NET_SKB_PAD and SKB_DATA_ALIGN(sizeof(struct skb_shared_info)) Final allocated size for skb head on x86_64 (L1_CACHE_BYTES = 64, MTU=1500) : 2112 bytes : SLUB/SLAB round this to 4096 bytes. Since skb truesize is then bigger than SK_MEM_QUANTUM, we have lot of false sharing because of mem_reclaim in UDP stack. One possible way to half truesize is to reduce the need by 64 bytes (2112 -> 2048 bytes) Instead of allocating a full cache line at the end of packet for alignment, we can use the fact that skb_shared_info sits at the end of skb->head, and we can use this room, if we convert bnx2x to new build_skb() infrastructure. skb_shared_info will be initialized after hardware finished its transfert, so we can eventually overwrite the final padding. Using build_skb() also reduces cache line misses in the driver, since we use cache hot skb instead of cold ones. Number of in-flight sk_buff structures is lower, they are recycled while still hot. Performance results : (820.000 pps on a rx UDP monothread benchmark, instead of 720.000 pps) Signed-off-by:
