Hi, i would also appreciate some newer Kernels. I'm experiencing really poor throughput (under 10 Mbit/s instead of Gigabit) with ip6gre on Debian and the 5.10 Kernel. I think this was resolved in newer Versions. I'm currently still searching which patch resolved this or what the preferred way forward should be. But being able to just use something current would be the easiest way for me. Cheers, Tom
