interface gif0 bouncing

[Jeffrey]

I have enabled a gif interface for use with Hurricane Electric for IPv6 connectivity.  I have noticed in the dmesg logs thousands of the message:

gif0: link state changed to UP
gif0: link state changed to DOWN

The IPv6 connectivity appears to be working fine however

Software on my unit from the dashboard page is:

OPNsense 19.1.1-amd64
FreeBSD 11.2-RELEASE-p8-HBSD
OpenSSL 1.0.2q 20 Nov 2018

Suggestions as to what I might need to change to correct the issue?

Thanks,
Jeff
