linux-toradex.git/net/openvswitch/flow_netlink.h, branch v3.14.9 Linux kernel for Apalis and Colibri modules openvswitch: Per cpu flow stats. 2014-01-06T23:52:24+00:00 Pravin B Shelar pshelar@nicira.com 2013-10-30T00:22:21+00:00 e298e505700604c97e6a9edb21cebb080bdb91f6 With mega flow implementation ovs flow can be shared between multiple CPUs which makes stats updates highly contended operation. This patch uses per-CPU stats in cases where a flow is likely to be shared (if there is a wildcard in the 5-tuple and therefore likely to be spread by RSS). In other situations, it uses the current strategy, saving memory and allocation time. Signed-off-by: Pravin B Shelar <pshelar@nicira.com> Signed-off-by: Jesse Gross <jesse@nicira.com>

openvswitch: Restructure datapath.c and flow.c 2013-10-04T01:16:47+00:00 Pravin B Shelar pshelar@nicira.com 2013-10-04T01:16:47+00:00 e64457191a259537bbbfaebeba9a8043786af96f Over the time datapath.c and flow.c has became pretty large files. Following patch restructures functionality of component into three different components: flow.c: contains flow extract. flow_netlink.c: netlink flow api. flow_table.c: flow table api. This patch restructures code without changing logic. Signed-off-by: Pravin B Shelar <pshelar@nicira.com> Signed-off-by: Jesse Gross <jesse@nicira.com> 
Over the time datapath.c and flow.c has became pretty large files.
Following patch restructures functionality of component into three
different components:

flow.c: contains flow extract.
flow_netlink.c: netlink flow api.
flow_table.c: flow table api.

This patch restructures code without changing logic.
