Hi Stephen!
The current version of our PMD supports only Linux x86_64 platforms.
Due to this, we have added a special condition to the meson.build file:
```
if not is_linux or not dpdk_conf.has('RTE_ARCH_X86_64')
build = false
reason = 'only supported on x86_64 Linux'
subdir_done()
endif
```
We prefer to use pthread for the current patch set and fix it later.
Best regards,
Serhii
NOTE: Please ignore the disclaimer. We are working on fix it.
