This patch adds the register dump format for FUJITSU Extended
Network device like the following:
# ethtool -d es0
0x: OWNER_EPID(Owner EPID) 0x0001
0x0004: MAX_EP(Maximum EP) 0x0008
0x0010: DCTL (Device C
There is no need to call ether_setup after alloc_ethdev since it was
already called there.

Some comments:
IIUC, the main struggle seems to be whether the redirect to dummy0
is useful or not? i.e instead of just letting the packets go up the
stack on eth1?
It seems like sflowd needs to read off eth1 via packet socket?
To be backward compatible - supporting that approach seems sensible.

This set improves the test_verifier and test_maps suite and moves
it over to a new BPF selftest directory, so we can keep improving
it under kernel selftest umbrella. This also integrates a test
script for checking test_bpf.ko under various JIT options.

This patch implements the following operations:
- Intermediate segment endpoint: incrementation of active segment and rerouting.
- Egress for SR-enc
Segment Routing (SR) is a source routing paradigm, architecturally
defined in draft-ietf-spring-segment-routing-09 [1]. The IPv6 flavor of
SR is defined in draft-ietf-6man-segment-routing-header-02 [2].
The main idea is that an SR-enabled packet contains a list of segments,
which represent mandato
This patch creates a new type of interfaceless lightweight tunnel (SEG6),
enabling the encapsulation and injection of SRH within locally emitted
packets and forwarded packets.
>From a configuration viewpoint, a seg6 tunnel would be configured as follows:
ip -6 ro ad fc00::1/128 via encap seg6
This patch adds the necessary functions to compute and check the HMAC signature
of an SR-enabled packet. Two HMAC algorithms are supported: hmac(sha1) and
hmac(sha256).
In order to avoid dynamic memory allocation for each HMAC computation,
a per-cpu ring buffer is allocated for this purpose.
Sign
This patch adds the necessary hooks and structures to provide support
for SR-IPv6 control plane, essentially the Generic Netlink commands
that will be used for userspace control over the Segment Routing
kernel structures.
The genetlink commands provide control over two different structures:
tunnel
This patch adds support for per-socket SRH injection with the setsockopt
system call through the IPPROTO_IPV6, IPV6_RTHDR options.
The SRH is pushed through the ipv6_push_nfrag_opts function.

This patch provides an implementation of the genetlink commands
to associate a given HMAC key identifier with an hashing algorithm
and a secret. It also provides a per-interface sysctl called
seg6_require_hmac, allowing a user-defined policy for processing
HMAC-signed SR-enabled packets. A value of

This patch prepares for insertion of SRH through setsockopt().
The new source address argument is used when an HMAC field is
present in the SRH, which must be filled. The HMAC signature
process requires the source address as input text.
