The following drivers have the same kind of issue.
Drivers with unsafe pthread_mutex:
net/
af_xdp
atlantic
axgbe
bnxt
ena
failsafe (see patch #2)
hinic
mlx5
qede
vhost
virtio
raw/
ifpga
vdpa/
ifc
mlx5
Another alternative would be to create a DPDK wrapper (rte_mutex?)
which had the proper semantics. That might make the Windows port easier.
But it would make backport to stable harder.
If this does not get fixed in April, we should change documentation
to warn users.
