Did you follow the instructions for enabling support for ingress policing in
"INSTALL.Linux"?
For optional support of ingress policing, you must enable kernel
configuration options NET_CLS_BASIC, NET_SCH_INGRESS, and
NET_ACT_POLICE, either built-in or as modules. (NET_CLS_POLICE is
obsolete and not needed.)
If you're running an older version of OVS, the instructions are as follows:
For optional support of ingress policing, you must enable kernel
configuration options NET_CLS_ACT, NET_CLS_U32, NET_SCH_INGRESS,
and NET_ACT_POLICE, either built-in or as modules.
(NET_CLS_POLICE is obsolete and not needed.)
I don't see some of the modules in your list below. Are they built into your
kernel?
