Having DPDK libraries as Rust crates would be beneficial as well. The
mempool library in particular is something I've wanted to use in some
Rust projects. I've previousl

A PMD could be software based (e.g. net_pcap). For such PMDs, Rust can
be a good option.

Hi,
I've noticed an issue of `rte_memory_get_nchannel()` or
`rte_memory_get_nrank()` always returning zero regardless of the -n or
-r options set.
I think this is due to `--in-memory` forcing `conf->no_shconf = 1`
[1], which leads to `rte_eal_memdevice_init()` never being executed
[2].

Sorry, I used the wrong --to and --cc switches.
Adding Slava just in case.

A number of `log_max_*` fields' types are unnecessarily large, and can
be reduced to `uint8_t`.

Thanks! No warnings now, except for "Wrong headline prefix" for the
first patch because it modifies both
issues.

Which overflows ring size and generates the following log:

as I do not have the NIC
programmer's manual.
Using anything larger than 8192 resulted in an error. Similarly,
anything in the [8193, 32768) range with the DPDK PMD results in an rx
queue allocation failure.
