====================
mlx5-updates-2021-03-29

Coexistence of CQE compression and HW PTP time-stamp:

From Aya this series improves mlx5 netdev driver to allow
both mlx5 CQE compression (RX descriptor compression, that saves on PCI
transaction) and HW time-stamp PTP to co-exists.

Prior to this series both features were mutually exclusive due to the
nature of CQE compression which reduces the size of RX descriptor for
the price of trimming some data, such as the time-stamp.

In order to allow CQE compression when PTP time stamping is enabled,
We enable it on the regular performance critical RX queues which will
service all the data path traffic that is not PTP.

PTP traffic will be re-directed to dedicated RX queues on which we will
not enable CQE compression and thus keep the time-stamp intact.

Having both features is critical for systems with low PCI BW, e.g.
Multi-Host.

The series will be adding:
1) Infrastructure to create a dedicated RX queue to service the PTP traffic
2) Flow steering plumbing to capture PTP traffic both UDP packets with
 destination port 319 and L2 packets with ethertype 0x88F7
3) Steer PTP traffic to the dedicated RX queue.
4) The feature will be enabled when PTP is being configured via the
   already existing PTP IOCTL when CQE compression is active, otherwise
   no change to the driver flow.
