Async enqueue offloads large copies to DMA devices, and small copies
are still performed by the CPU. However, it requires users to get
enqueue completed packets by rte_vhost_poll_enqueue_completed(), even
if they are completed by the CPU when rte_vhost_submit_enqueue_burst()
returns. This design incurs extra overheads of tracking completed
pktmbufs and function calls, thus degrading performance on small packets.
This patch enhances async enqueue for small packets by enabling
rte_vhost_submit_enqueue_burst() to return completed packets.

Two warnings are reported by gcc 9.3.0 on Ubuntu 20.04.
When producing a printable mac address the buffer was appropriately sized
for holding the mac address exactly, but the actual snprintf included a
'\n' character at the end, which means that the snprintf technically is
getting truncated i.e. the \n would not be added due to lack of space.
This gets flagged as a problem by modern versions of gcc, e.g. on Ubuntu
20.04.
main.c:77:37: warning: ‘__builtin___snprintf_chk’ output truncated
before the last format character [-Wformat-truncation=]
77 | "%02x:%02x:%02x:%02x:%02x:%02x\n",
| ^
Since the \n is getting stripped anyway, we can fix the issue by just
removing it. In the process we can switch to using the standard ethernet
address formatting function from rte_ether.h.
The other warning is about possible string truncation when getting the
RX queue name:
In file included from init.c:36:
init.c: In function ‘init’:
../shared/common.h:38:28: warning: ‘%u’ directive output may be truncated
writing between 1 and 10 bytes into a region of size 8

../shared/common.h:52:35: note: in expansion of macro ‘MP_CLIENT_RXQ_NAME’
52 | snprintf(buffer, sizeof(buffer), MP_CLIENT_RXQ_NAME, id);
| ^~~~~~~~~~~~~~~~~~
This is a false positive, as the value of the "id" is limited to 255,
being stored in the app as a uint8_t value, removing the possibility of
the %u being replaced by anything other then 3 characters max (rather than
up to 10 as thought by the compiler). Therefore, the warning can be easily
removed by changing the type of the "id" parameter to the local function
from "unsigned" to "uint8_t" also, ensuring the compiler is aware of the
range limit.
