We need to delete from offload the device externally learnded fdbs when any
one of these events happen:
1) Bridge ages out fdb. (When bridge is doing ageing vs. device doing
ageing. If device is doing ageing, it would send SWITCHDEV_FDB_DEL
directly).
2) STP state change flushes fdbs on port.
3) User uses sysfs interface to flush fdbs from bridge or bridge port:
echo 1 >/sys/class/net/BR_DEV/bridge/flush
echo 1 >/sys/class/net/BR_PORT/brport/flush
4) Offload driver send event SWITCHDEV_FDB_DEL to delete fdb entry.
For rocker, we can now get called to delete fdb entry in wait and nowait
contexts, so set NOWAIT flag when deleting fdb entry.

Clarify in documentation and code that IPV4 FIB add operation is used for
both adding a new FIB entry to the device and for modifying an existing FIB
entry on the device.
Also, remove left-over references to ipv4_fib ops and replace with details
on SWITCHDEV_PORT_IPV4_FIB object.

There were a few review comments on the switchdev.txt documentation that
didn't get included with the Spring Cleanup series, so include them now.

Much need updated of switchdev documentation to cover what's been
implmented to-date. There are some XXX comments in the text for
unimplemented or broken items. I'd like to keep these in there (poor-man's
TODO list) and update the document once each issue is resolved.

The goal of this is to provide a possibility to support various switch
chips. Drivers should implement relevant ndos to do so. Now there is
only one ndo defined:
- for getting physical switch id is in place.
Note that user can use random port netdevice to access the switch.
