[PATCH] staging: r8188eu: Add queue_index to xdp_rxq_info

From: Varshini Elangovan
Date: Thu Jun 02 2022 - 13:37:50 EST


Queue_index from the xdp_rxq_info is populated in cpumap file.
Using the NR_CPUS, results in patch check warning, as recommended,
using the num_possible_cpus() instead of NR_CPUS
