[net-next 03/15] net/mlx5e: Use page-sized fragments with XDP multi buffer

[Saeed Mahameed <saeed@kernel.org>]

From: Maxim Mikityanskiy <maximmi@nvidia.com>

The implementation of XDP in mlx5e assumes that the frame size is equal
to the page size. Force this limitation in the non-linear mode for XDP
multi buffer.
