net/mlx5e: Add data path for SHAMPO feature
The header buffer is used to store the headers of the rx packets.
The header buffer size deduced from WorkQueue size + restriction
of max packets per WorkQueueElement.
This commit adds the functionality for posting/updating memory for
the header buffer during the posting/updating of WQEs.
