cf5560a100 libzpci: opticsmon: Refactor on_link_change() using new zpci_find_by_netdev()
Finding a PCI device given the name of a netdev seems generally useful
so pull this out into a new zpci_find_by_netdev() function in libzpci
and use this to simplify on_link_change() removing the need for
backwards goto.

e0caed5534 libzpci: Add operational state for netdevs
The operational state is read from sysfs but can later also be updated
via AF_NETLINK.

8704c9c80e zpcictl: Pull SCLP handling out and into libzpci
The upcoming optics monitoring tool will have to issue SCLP Write Event
data just like zpcictl so pull that functionality out and into libzpci.
While at it decouple getting SMART data from the actual SCLP handling.
No change in behavior intended.

3a4c20b443 libzpci: Introduce libzpci
This introduces libzpci which is a library intended to handle s390x
specific PCI attributes and peculiarities. As a first step it introduces
code to list PCI devices on s390x including an initial set of s390x
specific attributes like FID, PFT, UID etc. It also collects information
on network device associated with a particular PCI function. The
included example serves as a demonstration of using libzpci to list PCI
devices.
