--- Comment #9 from nico...@deffayet.com ---
I confirm this bug on FreeBSD 11.0 RELEASE. Only igb interfaces are affected as
the issue don't occur with host using em instead of igb interfaces.
The crash seem to be related to a certain type and amount of packets.
Removing ALTQ support from kernel fix the issue.
It seem to be related to r303174. ALTQ seem to have not been supported with igb
interface according https://forums.freebsd.org/threads/48283/ and
https://lists.freebsd.org/pipermail/freebsd-pf/2016-August/008217.html
I suggest to test with r303174 removed:

Did you have the same issue with msix disabled ?
sysctl -w hw.pci.enable_msix=0
Not sure if this is true but MSI-IX and ALTQ seem to be incompatible.
