Would be interesting to know why nobody else hit such error?

What about #include <rte_ethdev_trace.h> ?

I only changed the .h files since that was enough to fix the issue, but I'll add that include as well.

Except this,
Acked-by: Thomas Monjalon <thomas@monjalon.net>

I would change the title to be more generic (nothing specific to gcc or Arm here):
	ethdev: fix local include

According to my research, the handling of include directives could be differenct across compilers so I made it specific, as I only looked at how gcc does it. The implementations are probably basically the same, so I'll change to wording so it's generic.

It needs to be backported, so these lines are required:
	Fixes: 7f0a669e7b04 ("ethdev: add allocation helper for virtual drivers")
	Fixes: dcd5c8112bc3 ("ethdev: add PCI driver helpers")
	Fixes: ffc905f3b856 ("ethdev: separate driver APIs")
	Fixes: 331c447ad913 ("ethdev: separate internal structures into own header")
	Cc: stable@dpdk.org

I didn't know which patches this fixes, so I'll add this. How should I figure this out? Just look at which patch(es) changed the lines I'm modifying?
