David S. Miller ecbcd689d7 mlx5e-updates-2018-07-26 (XDP redirect)
This series from Tariq adds the support for device-out XDP redirect.
 
 Start with a simple RX and XDP cleanups:
 - Replace call to MPWQE free with dealloc in interface down flow
 - Do not recycle RX pages in interface down flow
 - Gather all XDP pre-requisite checks in a single function
 - Restrict the combination of large MTU and XDP
 
 Since now XDP logic is going to be called from TX side as well,
 generic XDP TX logic is not RX only anymore, for that Tariq creates
 a new xdp.c file and moves XDP related code into it, and generalizes
 the code to support XDP TX for XDP redirect, such as the xdp tx sq
 structures and xdp counters.
 
 XDP redirect support:
 Add implementation for the ndo_xdp_xmit callback.
 
 Dedicate a new set of XDP-SQ instances to satisfy the XDP_REDIRECT
 requests.  These instances are totally separated from the existing
 XDP-SQ objects that satisfy local XDP_TX actions.
 
 Performance tests:
 
 xdp_redirect_map from ConnectX-5 to ConnectX-5.
 CPU: Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz
 Packet-rate of 64B packets.
 
 Single queue: 7 Mpps.
 Multi queue: 55 Mpps.
