x86_64 x86_64 x86_64 GNU/Linux bnx2x doesn't crash when vxlans are enabled.

The v4.9-rc8 upstream kernel is now available. It might be worthwhile to test
it:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.9-rc8/
If the bug still exists in -rc9, would it be possible for you to open an
upstream bug report[0]? That will allow the upstream Developers to
examine the
Kernel team, is there anything missing?
Thanks

Did this issue start happening after an update/upgrade? Was there a
prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.9
