/**
* Parse a series of data segments for page fault handling.
*
* @pfault contains page fault information.
* @wqe points at the first data segment in the WQE.
* @wqe_end points after the end of the WQE.
* @bytes_mapped receives the number of bytes that the function was able to
* map. This allows the caller to decide intelligently whether
* enough memory was mapped to resolve the page fault
* successfully (e.g. enough for the next MTU, or the entire
* WQE).
* @total_wqe_bytes receives the total data size of this WQE in bytes (minus
* the committed bytes).
* @dev: Pointer to mlx5 IB device
* @pfault: contains page fault information.
* @wqe: points at the first data segment in the WQE.
* @wqe_end: points after the end of the WQE.
* @bytes_mapped: receives the number of bytes that the function was able to
* map. This allows the caller to decide intelligently whether
* enough memory was mapped to resolve the page fault
* successfully (e.g. enough for the next MTU, or the entire
* WQE).
* @total_wqe_bytes: receives the total data size of this WQE in bytes (minus
* the committed bytes).
* @receive_queue: receive WQE end of sg list
*
* Returns the number of pages loaded if positive, zero for an empty WQE, or a
* negative error code.
