[PATCH net v3 0/2] bpf: devmap: provide rxq after redirect

Posted by Florian Kauer 2 months, 3 weeks ago

rxq contains a pointer to the device from where
the redirect happened. Currently, the BPF program
that was executed after a redirect via BPF_MAP_TYPE_DEVMAP*
does not have it set.

Add bugfix and related selftest.
