====================
net/mlx5e: Extend XDP multi-buffer capabilities

This series extends the XDP multi-buffer support in the mlx5e driver.

Patchset breakdown:
- Infrastructural changes and preparations.
- Add XDP multi-buffer support for XDP redirect-in.
- Use TX MPWQE (multi-packet WQE) HW feature for non-linear
  single-segmented XDP frames.
- Add XDP multi-buffer support for striding RQ.

In Striding RQ, we overcome the lack of headroom and tailroom between
the RQ strides by allocating a side page per packet and using it for the
xdp_buff descriptor. We structure the xdp_buff so that it contains
nothing in the linear part, and the whole packet resides in the
fragments.

Performance highlight:

Packet rate test, 64 bytes, 32 channels, MTU 9000 bytes.
CPU: Intel(R) Xeon(R) Platinum 8380 CPU @ 2.30GHz.
NIC: ConnectX-6 Dx, at 100 Gbps.

+----------+-------------+-------------+---------+
| Test     | Legacy RQ   | Striding RQ | Speedup |
+----------+-------------+-------------+---------+
| XDP_DROP | 101,615,544 | 117,191,020 | +15%    |
+----------+-------------+-------------+---------+
| XDP_TX   |  95,608,169 | 117,043,422 | +22%    |
