Comment 2 for bug 1961566

This issue is due to missing functionality in iproute2. Upstream commit 69629b4e43c4 from the iproute2 git repo adds the requisite functionality to fix this. Upstream 0486388a877 is required as a prerequisite for the target commit. Part of cfad32569f is also necessary to add the appropriate value to an enum. Specifically, the addition of SEG6_LOCAL_VRFTABLE to the SEG6 enum in include/uapi/linux/seg6_local.h.
