This is very similar to bnx2x conversion, but bnx2 only requires 16bytes alignement at start of the received frame to store its l2_fhdr, so goal was not to reduce skb truesize (in fact it should not change after this patch) Using build_skb() 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 more likely recycled in SLUB caches while still hot. Signed-off-by:

Most machines dont use RPS/RFS, and pay a fair amount of instructions in netif_receive_skb() / netif_rx() / get_rps_cpu() just to discover RPS/RFS is not setup. Add a jump_label named rps_needed. If no device rps_map or global rps_sock_flow_table is setup, netif_receive_skb() / netif_rx() do a single instruction instead of many ones, including conditional jumps. jmp +0 (if CONFIG_JUMP_LABEL=y) Signed-off-by:

This patch fixes a crash when non existing IPv6 route is tried to be changed. When new destination node was inserted in middle of FIB6 tree, no relevant sanity checks were performed. Later route insertion might have been prevented due to invalid request, causing node with no rt info being left in tree. When this node was accessed, a crash occurred. Patch adds missing checks in fib6_add_1() Signed-off-by:

Mark stats timer as deferrable: punctuality in waking the stats timer callback doesn't matter much, as it is responsible only to avoid integer wraparound. We need at least 1 other timer to fire within 17s (fully loaded 1Gbps) to avoid wrap-arounds. Desired period is still 10s. Signed-off-by:

This commit implements the ndo_get_stats64() API for forcedeth. Since hardware stats are being updated from different contexts (process and timer), this commit adds synchronization. For software stats, it relies on the u64_stats_sync.h API. Tested: - 16-way SMP x86_64 -> RX bytes:7244556582 (7.2 GB) TX bytes:181904254 (181.9 MB) - pktgen + loopback: identical rx_bytes/tx_bytes and rx_packets/tx_packets Signed-off-by: -

This adds a new module parameter "debug_tx_timeout" to silence most debug messages in case of TX timeout. These messages don't provide a signal/noise ratio high enough for production systems and, with ~30kB logged each time, they tend to add to a cascade effect if the system is already under stress (memory pressure, disk, etc.). By default, the parameter is clear, meaning that only a single warning will be reported. Signed-off-by:

This adds the /sys/class/net/DEV/queues/Q/tx_timeout attribute containing the total number of timeout events on the given queue. It is always available with CONFIG_SYSFS, independently of CONFIG_RPS/XPS. Credits to Stephen Hemminger for a preliminary version of this patch. Tested: without CONFIG_SYSFS (compilation only) with sysfs and without CONFIG_RPS & CONFIG_XPS with sysfs and without CONFIG_RPS with sysfs and without CONFIG_XPS with defaults Signed-off-by:

This change makes sure that tx_packets/rx_bytes ifconfig counters are updated even on NICs that don't provide hardware support for these stats: they are now updated in software. For the sake of consistency, we also now have tx_bytes updated in software (hardware counters include ethernet CRC, and software doesn't account for it). This reverts parts of: - "forcedeth: statistics optimization" (21828163) - "forcedeth: Improve stats counters" (0bdfea8b) - "forcedeth: remove unneeded stats updates" (4687f3f3) Tested: pktgen + loopback (http://patchwork.ozlabs.org/patch/124698/) reports identical tx_packets/rx_packets and tx_bytes/rx_bytes.

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:
