Hi,
I'm stumped by a weird development in measured CPU utilization when testing an
upgrade path from 3.14.70 to 4.4.14.
I'm running, on identical hardware (2 4-core Xeon E5420), a HA
(active/standby) pair of firewall/loadbalancer VMs. The OS on the host and the
VM is identical - openSUSE 13.1
Dear LVS users / netdev readers,
today I've got a pretty peculiar problem.
I've been running 3.14.48 (and some earlier 3.14 kernels) for a long time now
in an LVS / keepalived driven loadbalancing cluster. See below for more detail
on the setup.
Today I started to upgrade to the current 3.14.7

That is my understanding, yes. That macvlan device is created by
keepalived
Dear netdev,
I've got a peculiar issue, and hope for clarification / workarounds here.
Scenario:
- a bridge interface br0, over some ethernet base
- a macvlan interface br0-vrrp on top, set up by keepalived, with VRRP VMAC
- keepalived regularly sending gratuitous ARP with that VRRP VMAC
- (new)

Sorry, Grant - I'm sticking to 3.14.xx for now.

driver), I just encountered a full loss of connectivity through the 10 GE

On the console I could see this (timestamps omitted, have to type by hand,

Dear kernel developers,
I recently started to upgrade my production hosts and VMs from the 3.14 series
