I presume you're using some hardware (I'm guessing Mellanox?) that can actually do TLS offload? Unfortunately, I don't have any hardware that can do this, so I can't test the tls_device stuff.

Can you find out what source line this corresponds to?
RIP: 0010:skb_splice_from_iter+0x102/0x300
Assuming you're building your own kernel, something like the following might do the trick:
echo "RIP: 0010:skb_splice_from_iter+0x102/0x300" | ./scripts/decode_stacktrace.sh /my/built/vmlinux /my/build/tree
if you run it in the kernel source tree you're using and substitute the paths to vmlinux and the build tree for modules.
