Hi John,
Is it possible to try the attached patch?
I am not sure if it actually fixes the issue. But I think it is worth a try.
Also, could you get me all the ipv6 routes when you plug in the usb
using "ip -6 route show"? (If you have multiple routing tables
configured, could you dump them all?)

Currently, eBPF only understands BPF_JGT (>), BPF_JGE (>=),
BPF_JSGT (s>), BPF_JSGE (s>=) instructions, this means that
particularly *JLT/*JLE counterparts involving immediates need
to be rewritten from e.g. X < [IMM] by swapping arguments into

This work implements jiting of BPF_J{LT,LE} instructions with
BPF_X/BPF_K variants for the nfp eBPF JIT. The two BPF_J{SLT,SLE}
instructions have not been added yet given BPF_J{SGT,SGE} are

Do not use uarg->zerocopy outside msg_zerocopy. In other paths the
field is not explicitly initialized and aliases another field.
Those paths have only one reference so do not need this intermediate

Hi,
I am debugging a system where rcu_sched detects cpu stall. The system
is running a test which runs fine if IPSec is not used. With IPSec it
stalls. I have tried reducing the value of netdev_budget to 100 but
that seems to have no impact. I have included two stack traces below.
