They are not accessible from\nthe Virtual Functions.\n\nMoreover, attempting to access these registers crashes the kernel:\n\n$ echo 1 > /sys/bus/pci/devices/0000\\:00\\:00.0/sriov_numvfs\npci 0000:00:01.0: [1957:ef00] type 00 class 0x020001\nfsl_enetc_vf 0000:00:01.0: Adding to iommu group 15\nfsl_enetc_vf 0000:00:01.0: enabling device (0000 -> 0002)\nfsl_enetc_vf 0000:00:01.0 eno0vf0: renamed from eth0\n$ tc qdisc replace dev eno0vf0 root taprio num_tc 8 map 0 1 2 3 4 5 6 7 \\\n\tqueues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 base-time 0 \\\n\tsched-entry S 0x7f 900000 sched-entry S 0x80 100000 flags 0x2\nUnable to handle kernel paging request at virtual address ffff800009551a08\nInternal error: Oops: 96000007 [#1] PREEMPT SMP\npc : enetc_setup_tc_taprio+0x170/0x47c\nlr : enetc_setup_tc_taprio+0x16c/0x47c\nCall trace:\n enetc_setup_tc_taprio+0x170/0x47c\n enetc_setup_tc+0x38/0x2dc\n taprio_change+0x43c/0x970\n taprio_init+0x188/0x1e0\n qdisc_create+0x114/0x470\n tc_modify_qdisc+0x1fc/0x6c0\n rtnetlink_rcv_msg+0x12c/0x390\n\nSplit enetc_setup_tc() into separate functions for the PF and for the\nVF drivers.
