Hi guys:
I hava test environment as below:
ENV: Neutron + ovs(2.1.2) with linux bond(eth2,eth3), vm in compute node
couldn't get ip from dhcp server.
I had flow [1] added in br-int, and with eth2 and eth3 GRO on, the kernel
cache flow was [3],and packets droped. But with eth2 and eth3 GRO off, the
kernel cache flow was[2], and the packets will be forward with pop_vlan, and
works OK.
In the failed situation, I found error msg in log as below:
openvswitch: netlink: Flow modification message rejected, unmasked key does
not match.
Anyone have idea about what wrong about ovs does not works with the linux bond?
OVS can't get field of vlan to match for packets from linux bond port with gro
on?
