netdevsim: don't embed file_operations into your structs
Just use debugfs_get_aux() instead of debugfs_real_fops().

netdevsim: Introduce support for L3 offload xstats
Add support for testing of HW stats support that was added recently, namely
the L3 stats support. L3 stats are provided for devices for which the L3
stats have been turned on, and that were enabled for netdevsim through a
debugfs toggle:
# echo $ifindex > /sys/kernel/debug/netdevsim/$DEV/hwstats/l3/enable_ifindex
For fully enabled netdevices, netdevsim counts 10pps of ingress traffic and
20pps of egress traffic. Similarly, L3 stats can be disabled for a given
device, and netdevsim ceases pretending there is any HW traffic going on:
# echo $ifindex > /sys/kernel/debug/netdevsim/$DEV/hwstats/l3/disable_ifindex
Besides this, there is a third toggle to mark a device for future failure:
# echo $ifindex > /sys/kernel/debug/netdevsim/$DEV/hwstats/l3/fail_next_enable
A future request to enable L3 stats on such netdevice will be bounced by
netdevsim:
# ip -j l sh dev d | jq '.[].ifindex'
66
# echo 66 > /sys/kernel/debug/netdevsim/netdevsim10/hwstats/l3/enable_ifindex
# echo 66 > /sys/kernel/debug/netdevsim/netdevsim10/hwstats/l3/fail_next_enable
# ip stats set dev d l3_stats on
Error: netdevsim: Stats enablement set to fail.
