Can you repeat your test, disabling gro splitting in cake?

the option is "no-split-gso"

Still panics. Takes a couple of rounds, but panics.

Moreover, I've stressed my HTB setup like this too for a longer time, 
and it panics as well. So, at least, now I have a proof this is not a 
CAKE-specific thing.

Also, I've stressed it even with noqueue, and the panic is still there. 
So, this thing is not even sch-specific.

Next, I've seen GRO bits in the call trace and decided to disable GRO on 
this NIC. So far, I cannot trigger a panic with GRO disabled even after 
20 rounds of speedtest.

So, must be some generic thing indeed.
