staging: fsl-dpaa2/eth: Update number of netdev queues (bb5b42c0) · Commits · 戴 / test

Currently, the netdevice is allocated with a default number of Rx/Tx queues equal to CONFIG_NR_CPUS, meaning the maximum number of cores supported by the current kernel. The actual number of queues is reflected by the DPNI object attribute, so update the netdevice configuration based on that. Signed-off-by:
