Hi, can you help me to understand this part here? I believe that this
will lead to userspace sending a OVS_ACTION_ATTR_PUSH_ETH action
argument to the kernel that is different from what the kernel actually
wants. What's the idea, and how is that problem avoided?
struct ovs_action_push_eth {
struct ovs_key_ethernet addresses;
#ifndef __KERNEL__
__be16 eth_type;
#endif
};
Thanks,
Ben.
