Subject: net/mlx5e: Use page-sized fragments with XDP multi buffer
Patch-mainline: v5.18-rc1
Git-commit: d51f4a4cca6f629927b1871af0c6f5ce7a9022e9
References: jsc#PED-1549

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.
