The netdevsim driver previously lacked RX statistics support, which prevented its use with the GenerateTraffic() test framework, as this framework verifies traffic flow by checking RX byte counts.
This patch migrates netdevsim from its custom statistics collection to the NETDEV_PCPU_STAT_DSTATS framework, as suggested by Jakub. This change not only standardizes the statistics handling but also adds the necessary RX statistics support required by the test framework.
