[PATCH net-next 0/3] net/mlx5: use indirect call wrappers

[Paolo Abeni <pabeni@redhat.com>]

The mlx5_core driver uses several indirect calls in fast-path, some of them
are invoked on each ingress packet, even for the XDP-only traffic.

This series leverage the indirect call wrappers infrastructure the avoid
the expansive RETPOLINE overhead for 2 indirect calls in fast-path.

Each call is addressed on a different patch, plus we need to introduce a couple
of additional helpers to cope with the higher number of possible direct-call
alternatives.

  net/mlx5e: use indirect calls wrapper for skb allocation
  indirect call wrappers: add helpers for 3 and 4 ways switch
  net/mlx5e: use indirect calls wrapper for the rx packet handler
