Add support to count upall packets, when kmod of openvswitch upcall to count the number of packets for upcall succeed and failed, which is a better way to see how many packets upcalled on every interfaces.
Signed-off-by: wangchuanlei <wangchuan...@inspur.com> --- ovs-kmod already support count statistic of interfaces, the link is below, and this commit is the part of userspace. https://git.kernel.org/netdev/net-next/c/1933ea365aa7 note: this commit is compatible with old version of ovs-kmod, that is, even the kernel is older, and do not support count statistic of interfaces(do not have the code in upper link), this part of code is still stable! include/linux/openvswitch.h | 19 +++++++++++++++++++ include/openvswitch/netdev.h | 3 +++ lib/dpctl.c | 2 ++ lib/dpif-netlink.c | 13 +++++++++++++ lib/dpif-netlink.h | 2 ++ lib/netdev-linux.c | 8 ++++++++ 6 files changed, 47 insertions(+) diff --git a/include/linux/openvswitch.h b/include/linux/openvswitch.h index 8bb5abdc8..ff2dc58c9 100644 --- a/include/linux/openvswitch.h +++ b/include/linux/openvswitch.h @@ -141,6 +141,11 @@ struct ovs_vport_stats { __u64 tx_dropped;
