The net\ncore therefore leaves dev-\u003etstats NULL for PFCP devices.\n\nCreating a PFCP rtnetlink device can immediately ask the new netdev for\nstats while building the RTM_NEWLINK notification.  That reaches\ndev_get_tstats64() and dereferences the NULL dev-\u003etstats pointer.\n\nSet pcpu_stat_type to NETDEV_PCPU_STAT_TSTATS during PFCP link setup so\nthe net core allocates the storage expected by dev_get_tstats64()."
