Subject: [RFC PATCH bpf-next 2/9] selftests/bpf: fib_lookup: Enable forwarding on second net device
Date: Thu, 26 Feb 2026 09:59:56 +0200 [thread overview]
Message-ID: <20260226080003.524935-3-idosch@nvidia.com> (raw)
In-Reply-To: <20260226080003.524935-1-idosch@nvidia.com>
Currently, the bpf_fib_lookup() helper is only called with the ifindex
of veth1. In preparation for calling the bpf_fib_lookup() helper with
the ifindex of veth2, enable forwarding on this device.
