The following patch enables sending notifications also for events on FDB
entries that weren't added by the user. Give the drivers the information
necessary to distinguish between the two origins of FDB entries.

To maintain the current behavior, have switchdev-implementing drivers
bail out on notifications about non-user-added FDB entries. In case of
mlxsw driver, allow a call to mlxsw_sp_span_respin() so that SPAN over
bridge catches up with the changed FDB.

Some chips have a non-zero function id, however instead of hardcoding
the id's (CSIAR_FUNC_NIC and CSIAR_FUNC_NIC2) we can get them
dynamically via PCI_FUNC(pci_dev->devfn). This way we can get rid
of the csi_ops.

In general csi is just a fallback mechanism for PCI config space
access in case no native access is supported. Therefore let's
try native access first.

I checked with Realtek regarding the functionality of config space
byte 0x070f and according to them it controls the L0s/L1
entrance latency.
Currently ASPM is disabled in general and therefore this value
isn't used. However we may introduce a whitelist for chips
where ASPM is known to work, therefore let's keep this code.

the ranges of 8192~9216 and 9217~12287 are valid only for LGE/CGE, and are
always 0 for GE interfaces. it is easy to cause confusion when viewing the

The intention is to get notified of process failures as soon
as possible, before a possible core dumping (which could be very long)
(e.g. in some process-manager). Coredump and exit process events
are perfect for such use cases (see 2b5faa4c "connector: Added
coredumping event to the process connector").

The problem is that for now the process-manager cannot know the parent
of a dying process using connectors. This could be useful if the
process-manager should monitor for failures only children of certain
parents, so we could filter the coredump and exit events by parent
process and/or thread ID.

Add parent pid and tgid to coredump and exit process connectors event
data.
