[ Upstream commit 56c09de347e40804fc8dad155272fb9609e0a97b ]
Currently, trying to change the DF parameter of a geneve device does
nothing:
# ip -d link show geneve1
14: geneve1: <snip>
link/ether <snip>
geneve id 1 remote 10.0.0.1 ttl auto df set dstport 6081 <snip>
# ip link set geneve1 type geneve id 1 df unset
# ip -d link show geneve1
14: geneve1: <snip>
link/ether <snip>
geneve id 1 remote 10.0.0.1 ttl auto df set dstport 6081 <snip>
We just need to update the value in geneve_changelink.
Fixes: a025fb5f49ad ("geneve: Allow configuration of DF behaviour")
