2009-08-06vxge: prefetch skb->dataBenjamin LaHaise2-1/+6
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.

2009-08-06vxge: prefetch RxD descriptorsBenjamin LaHaise2-0/+2
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%.

2009-08-06vxge: fix pktgen hangs (don't abuse skb->cb[])Benjamin LaHaise5-32/+40
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.

2009-08-06vxge: don't drop frame on tx queue fullBenjamin LaHaise1-0/+6
The vxge driver will drop a packet in its transmit function if the number of TxDs available hits 0.

2009-08-06ixgbe: allow vlan egress priority mapping in DCB modeLucy Liu1-1/+1
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.

2009-08-06net: implement a SO_DOMAIN getsockoptionJan Engelhardt20-0/+24
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).

2009-08-06net: implement a SO_PROTOCOL getsockoptionJan Engelhardt20-0/+40
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: Jan Engelhardt <jengelh@medozas.de> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-08-03neigh: Convert garbage collection from softirq to workqueueEric Dumazet2-48/+45
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: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-07-31xfrm: select sane defaults for xfrm[4|6] gc_threshNeil Horman6-14/+40
Choose saner defaults for xfrm[4|6] gc_thresh values on init Currently, the xfrm[4|6] code has hard-coded initial gc_thresh values (set to 1024). Given that the ipv4 and ipv6 routing caches are sized dynamically at boot time, the static selections can be non-sensical. This patch dynamically selects an appropriate gc threshold based on the corresponding main routing table size, using the assumption that we should in the worst case be able to handle as many connections as the routing table can. For ipv4, the maximum route cache size is 16 * the number of hash buckets in the route cache. Given that xfrm4 starts garbage collection at the gc_thresh and prevents new allocations at 2 * gc_thresh, we set gc_thresh to half the maximum route cache size. For ipv6, its a bit trickier. there is no maximum route cache size, but the ipv6 dst_ops gc_thresh is statically set to 1024. It seems sane to select a simmilar gc_thresh for the xfrm6 code that is half the number of hash buckets in the v6 route cache times 16 (like the v4 code does).
