IB/core: Remove ib_uverbs_flow_spec structure from userspace
The structure holding any types of flow_spec is of no use to
userspace. It would be wrong for userspace to do:
struct ib_uverbs_flow_spec flow_spec;
flow_spec.type = IB_FLOW_SPEC_TCP;
flow_spec.size = sizeof(flow_spec);
Instead, userspace should use the dedicated flow_spec structure for
- Ethernet : struct ib_uverbs_flow_spec_eth,
- IPv4 : struct ib_uverbs_flow_spec_ipv4,
- TCP/UDP : struct ib_uverbs_flow_spec_tcp_udp.
In other words, struct ib_uverbs_flow_spec is a "virtual" data
structure that can only be use by the kernel as an alias to the other.
