Since it replaces sys/queue.h, then maybe sys_queue.h (or =
rte_sys_queue.h).

But more importantly:
It is not really DPDK, and thus shouldn't really be part of the EAL.
So here's an idea:
As part of de-bloating the EAL, can we somehow add a new directory =
structure for independent "libraries" like this?
And treat this rte_queue.h file as a "header file only" library, and put =
it there.
Then, build wise, the EAL could depend on this "library".
