This patch skips flushing static fdb entries in
ndo_stop, but flushes all fdb entries during vxlan
device delete. This is consistent with the bridge
driver fdb

This makes sense but isn't this a uAPI change? Do you know whether
there are users relying on the current behavior?

yeah, i have debated about this also. I am sitting on a stash of such patches
which are borderline bug fixes but been out there long enough that people might care.

I leaned towards making it the default because,
- I am assuming not many people use static entries
- and people will not be very unhappy with this change....because it does not delete something
 they had...just retains them.
- Per device flag seems like an overkill here

Also, i think some such changes were done to the bridge driver too after it was out.
