When compiling each file, the CPU flags are given as RTE_MACHINE_CPUFLAG_*
and in the list RTE_COMPILE_TIME_CPUFLAGS.
RTE_MACHINE_CPUFLAG_* are used to check the CPU features when compiling.
The list RTE_COMPILE_TIME_CPUFLAGS is used only to check the CPU at
runtime in the function rte_cpu_check_supported(). So it is not needed to
define this list for every files.
That's why RTE_COMPILE_TIME_CPUFLAGS is removed from the common variable
MACHINE_CFLAGS and is added only to the CFLAGS of eal_common_cpuflags.c.

Issuing a zero objects dequeue with a single consumer has no effect.
Doing so with multiple consumers, can get more than one thread to succeed
the compare-and-set operation and observe starvation or even deadlock in
the while loop that checks for preceding dequeues. The problematic piece
of code when n = 0:
cons_next = cons_head + n;
success = rte_atomic32_cmpset(&r->cons.head, cons_head, cons_next);
The same is possible on the enqueue path.

In certain autotests lpm->max_rules turned out to be non initialized.
That was caused by a failing allocation for lpm->rules_tbl in rte_lpm6_create.
It then left the function via goto exit with lpm freed, but still a pointer

In case of an allocation failure it resets lpm to NULL now, to avoid the

We have to reset the virtio net hdr at virtio_enqueue_offload()
before, due to all mbufs share a single virtio_hdr structure:
struct virtio_net_hdr_mrg_rxbuf virtio_hdr = {{0, }, 0};
foreach (mbuf) {
virtio_enqueue_offload(mbuf, &virtio_hdr.hdr);
copy net hdr and mbuf to desc buf
}
However, after the vhost rxtx refactor, the code looks like:
copy_mbuf_to_desc(mbuf)
{
struct virtio_net_hdr_mrg_rxbuf virtio_hdr = {{0, }, 0}
virtio_enqueue_offload(mbuf, &virtio_hdr.hdr);
copy net hdr and mbuf to desc buf
}
foreach (mbuf) {
copy_mbuf_to_desc(mbuf);

with body buffers. This allows for non-jumbo frames to only
use one mbuf (from primary ring); and jumbo frames will have
