[PATCH rdma-core 14/17] verbs: Use kernel uapi header for flow steering types

[Jason Gunthorpe <jgg-uk2M96/98Pc@public.gmane.org>]

From: Jason Gunthorpe <jgg-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

The kernel versions are a bit different, they have a union
around the header fields mapping to ib_uverbs_flow_spec_hdr
but are otherwise the same.

Performed by this script:

$ sed -i \
 -e 's/struct[ \t]ibv_kern_spec_action_drop\([ \t,)]\)/struct ib_uverbs_flow_spec_action_drop\1/g' \
 -e 's/struct[ \t]ibv_kern_spec_action_tag\([ \t,)]\)/struct ib_uverbs_flow_spec_action_tag\1/g' \
 -e 's/struct[ \t]ibv_kern_spec_eth\([ \t,)]\)/struct ib_uverbs_flow_spec_eth\1/g' \
 -e 's/struct[ \t]ibv_kern_spec_ipv4_ext\([ \t,)]\)/struct ib_uverbs_flow_spec_ipv4\1/g' \
 -e 's/struct[ \t]ibv_kern_spec_ipv6\([ \t,)]\)/struct ib_uverbs_flow_spec_ipv6\1/g' \
 -e 's/struct[ \t]ibv_kern_spec_tcp_udp\([ \t,)]\)/struct ib_uverbs_flow_spec_tcp_udp\1/g' \
 -e 's/struct[ \t]ibv_kern_spec_tunnel\([ \t,)]\)/struct ib_uverbs_flow_spec_tunnel\1/g' \
    `git ls-files`

And some minor touch ups.
