David S. Miller 65d51f2682 mlx5-updates-2018-01-08
Four patches from Or that add Hairpin support to mlx5:
 ===========================================================
 From:  Or Gerlitz <ogerlitz@mellanox.com>
 
 We refer the ability of NIC HW to fwd packet received on one port to
 the other port (also from a port to itself) as hairpin. The application API
 is based
 on ingress tc/flower rules set on the NIC with the mirred redirect
 action. Other actions can apply to packets during the redirect.
 
 Hairpin allows to offload the data-path of various SW DDoS gateways,
 load-balancers, etc to HW. Packets go through all the required
 processing in HW (header re-write, encap/decap, push/pop vlan) and
 then forwarded, CPU stays at practically zero usage. HW Flow counters
 are used by the control plane for monitoring and accounting.
 
 Hairpin is implemented by pairing a receive queue (RQ) to send queue (SQ).
 All the flows that share <recv NIC, mirred NIC> are redirected through
 the same hairpin pair. Currently, only header-rewrite is supported as a
 packet modification action.
 
 I'd like to thanks Elijah Shakkour <elijahs@mellanox.com> for implementing this
 functionality
 on HW simulator, before it was avail in the FW so the driver code could be
 tested early.
 ===========================================================
 
 From Feras three patches that provide very small changes that allow IPoIB
 to support RX timestamping for child interfaces, simply by hooking the mlx5e
 timestamping PTP ioctl to IPoIB child interface netdev profile.
 
 One patch from Gal to fix a spilling mistake.
 
 Two patches from Eugenia adds drop counters to VF statistics
 to be reported as part of VF statistics in netlink (iproute2) and
 implemented them in mlx5 eswitch.
