====================
net/mlx5: Avoid payload in skb's linear part for better GRO-processing

This is V7 of a series originally submitted by Christoph.

When LRO is enabled on the MLX, mlx5e_skb_from_cqe_mpwrq_nonlinear
copies parts of the payload to the linear part of the skb.

This triggers suboptimal processing in GRO, causing slow throughput.

This patch series addresses this by using eth_get_headlen to compute the
size of the protocol headers and only copy those bits. This results in a
significant throughput improvement (detailed results in the specific
patch).
