[v2] app/test:subprocess synchronization of parameters
Checks
Commit Message
In meson_test, because the child process does not synchronize
the NIC startup parameters of the parent process at startup,
it uses all NICs bound by vfio as startup parameters by default,
and an exception occurs in the subsequent hugefile check,
causing the test to fail. Synchronize the NIC startup parameters
of the parent process to the child process to solve this problem.
Fixes: af75078fece3 ("first public release")

Changes since v1:
- change the patch title to modify the way child
processes get NIC parameters
