This patch implements prefetching of skb->data from a copy of the pointer in the descriptor (which is already in the L1 cache at this point). This improves netperf rx performance (netperf -L 0,0 -c -H 192.168.254.2 -- -M 131072 -m 131072) by 4.9% on a P4 Xeon host. Signed-off-by:

This patch prefetches RxD descriptors which helps to lower the latency of a cache miss in vxge_hw_ring_rxd_next_completed. This lowers the % of CPU time used by vxge_hw_ring_rxd_next_completed() where the descriptor is accessed in profiling netperf on a P4 Xeon from 1.5% to 1.0%. Signed-off-by:

wmb() is extremely heavy on x86. The semantics required in the driver are provided by mmiowb(), so use that and improve tx performance on P4 Xeons by 5-10%. Signed-off-by:

This patch fixes a case in the transmit completion code which was resulting in pktgen hanging at the end of a run. The cause is due to the fact that the ->cb[] area of an skb cannot be used in a network driver's transmit path, as that area belongs to the network protocol. Pktgen hangs, as it sends out the same packet multiple times, and vxge's use of this area of the skb for a temporary list can only add the packet to the temporary list once (while it may be on the queue many times). The fix is to remove this abuse of skb->cb[]. Instead, skb pointers are placed into a temporary stack array, and then free outside of the tx lock. This retains the smp optimization of doing dev_kfree_skb() outside of the tx lock. Signed-off-by:

The vxge driver will drop a packet in its transmit function if the number of TxDs available hits 0. Instead of doing that, simply stop the transmit queue when transmitting a packet with the last available TxD. Signed-off-by:

The skb priority to vlan-qos egress mapping that can be configured using set_egress_map with vconfig is overriden by the DCB code in the driver. This patch allows this existing mechanism to work and will increase the configuration flexibility of DCB mode on Linux. A hierarchy of configuration is: 1. Modifies the ixgbe_select_queue() routine for DCB mode to return the priority value from the VLAN tag. It will normally be zero, unless the egress priority map has modified it. This will get packets into the correct queue and result in the queue_mapping field being set correctly. 2. Any tc filter which modifies queue_mapping will be honored, as the filters are handled after the vlan egress map is handled. Signed-off-by:

This patch is a bug fix to avoid system going into a bad state when driver is loaded in context of kdump kernel. The patch fixes the issue by performing a soft reset of pci function at probe time. Signed-off-by:

This sockopt goes in line with SO_TYPE and SO_PROTOCOL. It makes it possible for userspace programs to pass around file descriptors — I am referring to arguments-to-functions, but it may even work for the fd passing over UNIX sockets — without needing to also pass the auxiliary information (PF_INET6/IPPROTO_TCP).

Similar to SO_TYPE returning the socket type, SO_PROTOCOL allows to retrieve the protocol used with a given socket. I am not quite sure why we have that-many copies of socket.h, and why the values are not the same on all arches either, but for where hex numbers dominate, I use 0x1029 for SO_PROTOCOL as that seems to be the next free unused number across a bunch of operating systems, or so Google results make me want to believe. SO_PROTOCOL for others just uses the next free Linux number, 38. Signed-off-by:

Add support to handle aggregate packets from firmware. Local TCP flows are automatically identified by firmware based on the dest IP hash added by driver for local IP addresses. The packets are sent down on the jumbo rx ring. Signed-off-by:

This patch adds support for fixed PHY connected in MII mode to cpmac. We allow external and dumb_switch module parameters to override the PHY detection process since they are always connected with MDIO bus identifier 0. This lets fixed PHYs to be detected correctly and be connected to the their corresponding MDIO bus identifier. Signed-off-by:

Current neigh_periodic_timer() function is fired by timer IRQ, and scans one hash bucket each round (very litle work in fact) As we are supposed to scan whole hash table in 15 seconds, this means neigh_periodic_timer() can be fired very often. (depending on the number of concurrent hash entries we stored in this table) Converting this to a workqueue permits scanning whole table, minimizing icache pollution, and firing this work every 15 seconds, independantly of hash table size. This 15 seconds delay is not a hard number, as work is a deferrable one. Signed-off-by:

This renames away a variable clash: * ipv6_table[] is declared as a static global table; * ipv6_sysctl_net_init() uses ipv6_table to refer/destroy dynamic memory; * ipv6_sysctl_net_exit() also uses ipv6_table for the same purpose; * both the two last functions call kfree() on ipv6_table.
