netif_napi_del is called implicitely by free_netdev, therefore we
don't have to do it explicitely.
When the probe error path is reached, the net_device isn't
registered yet. Therefore reordering the call to netif_napi_del
shouldn't cause any issues.

Suggested by Arnd Bergmann
2 Add of_clk.name = "PCLK" to be explicit on
VDSO needs real-time cycle count to ensure the time accuracy.
Unlike others, nds32 architecture does not define clock source,
hence VDSO needs atcpit100 offering real-time cycle count
to derive the correct time.

The function call paths are:

Implement an ILA resolver. This uses LWT to implement the hook to a

backend net resolver.
The idea is that the kernel sets an ILA resolver route to the

ip route add ::/64 encap ila-resolve \

Add a netlink family to processe netlinkf for the ILA resolver.
This calls the net resolver netlink functions.

This patch implements the backend of a resolver, specifically it
provides a means to track unresolved addresses and expire entries
based on timeout.
The resolver is mostly a frontend to an rhashtable where the key
of the table is whatever address type or object is tracked. A resolver
instance is c
Add ILA_CMD_FLUSH netlink command to clear the ILA translation table.

Add interfaces into resolver backend that can be used to provide

Create a main ila file that contains the module intialization functions
as well as netlink definitions. Previously these were defined in
ila_xlat and ila_common. This approach allows better extensibility.

This patch implements generic in-kernel network resolver. The idea is
that an LWT "resolver" route is set in the kernel to cover some prefix.
When a packet hits the route a netlink message is fired to request
resolution and pending resolutions are tracked in a table.
Route resolution works in the

Perform better EAGAIN handling, handle case where ila_dump_info
fails and we miss mis objects in the dump, and add a skip index
to skip over ila entires in a list on a rhashtable node that have
already been visited (by a previous call to ila_nl_dump).

Still seems kinda odd to overload IFLA_VLAN_FLAGS to carry

Commit e87c6bc3852b ("bpf: permit multiple bpf attachments
for a single perf event") added support to attach multiple
bpf programs to a single perf event.
Although this provides flexibility, users may want to know
what other bpf programs attached to the same tp interface.
Besides getting visibility
Added a subtest in test_progs. The tracepoint is
sched/sched_switch. Multiple bpf programs are attached to
this tracepoint and the query interface is exercised.

Hello Stefan,
Thanks for this page!
I have applied your patch, and made a few tweaks, but
I have some minor questions. Please see below.
