Currently the driver will schedule isoc transfers immediately on the
next interval, which is quite aggressive when the interval is 125us.
There's report that some platforms may need more time to process the
transfer, otherwise the controller may miss the first interval. Let's
keep it simple and give the controller at least 500us to schedule the
isoc transfer.

This leads to various memory leaks and can be found in

====================
netdevsim: Support for L3 HW stats
"L3 stats" is a suite of interface statistics aimed at reflecting traffic
taking place in a HW device, on an object corresponding to some software
netdevice. Support for this stats suite has been added recently, in commit
ca0a53dcec ("Merge branch 'net-hw-counters-for-soft-devices'").
In this patch set:
- Patch #1 adds support for L3 stats to netdevsim.
Real devices can have various conditions for when an L3 counter is
available. To simulate this, netdevsim maintains a list of devices
suitable for HW stats collection. Only when l3_stats is enabled on both a
netdevice itself, and in netdevsim, will netdevsim contribute values to
L3 stats.
This enablement and disablement is done via debugfs:
# echo $ifindex > /sys/kernel/debug/netdevsim/$DEV/hwstats/l3/enable_ifindex
# 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
- This allows HW-independent testing of stats reporting and in-kernel APIs,
as well as a test for enablement rollback, which is difficult to do
otherwise. This netdevsim-specific selftest is added in patch #2.
- Patch #3 adds another driver-specific selftest, namely a test aimed at
checking mlxsw-induced stats monitoring events.

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
