      sctp: add support for setting flowlabel when adding a transport · 4be4139f
      由 Xin Long 提交于 
      Struct sockaddr_in6 has the member sin6_flowinfo that includes the
ipv6 flowlabel, it should also support for setting flowlabel when
adding a transport whose ipaddr is from userspace.

Note that addrinfo in sctp_sendmsg is using struct in6_addr for
the secondary addrs, which doesn't contain sin6_flowinfo, and
it needs to copy sin6_flowinfo from the primary addr.

      sctp: add spp_ipv6_flowlabel and spp_dscp for sctp_paddrparams · 0b0dce7a
      由 Xin Long 提交于 
      spp_ipv6_flowlabel and spp_dscp are added in sctp_paddrparams in
this patch so that users could set sctp_sock/asoc/transport dscp
and flowlabel with spp_flags SPP_IPV6_FLOWLABEL or SPP_DSCP by
SCTP_PEER_ADDR_PARAMS , as described section 8.1.12 in RFC6458.

As said in last patch, it uses '| 0x100000' or '|0x1' to mark
flowlabel or dscp is set,  so that their values could be set
to 0.

Note that to guarantee that an old app built with old kernel
headers could work on the newer kernel, the param's check in
sctp_g/setsockopt_peer_addr_params() is also improved, which
follows the way that sctp_g/setsockopt_delayed_ack() or some
other sockopts' process that accept two types of params does.

      sctp: add support for dscp and flowlabel per transport · 8a9c58d2
      由 Xin Long 提交于 
      Like some other per transport params, flowlabel and dscp are added
in transport, asoc and sctp_sock. By default, transport sets its
value from asoc's, and asoc does it from sctp_sock. flowlabel
only works for ipv6 transport.

Other than that they need to be passed down in sctp_xmit, flow4/6
also needs to set them before looking up route in get_dst.

Note that it uses '& 0x100000' to check if flowlabel is set and
'& 0x1' (tos 1st bit is unused) to check if dscp is set by users,
so that they could be set to 0 by sockopt in next patch.

      ipv4: add __ip_queue_xmit() that supports tos param · 69b9e1e0
      由 Xin Long 提交于 
      This patch introduces __ip_queue_xmit(), through which the callers
can pass tos param into it without having to set inet->tos. For
ipv6, ip6_xmit() already allows passing tclass parameter.

It's needed when some transport protocol doesn't use inet->tos,
like sctp's per transport dscp, which will be added in next patch.

      net: dsa: Add Vitesse VSC73xx DSA router driver · 05bd97fc
      由 Linus Walleij 提交于 
      This adds a DSA driver for:

Vitesse VSC7385 SparX-G5 5-port Integrated Gigabit Ethernet Switch
Vitesse VSC7388 SparX-G8 8-port Integrated Gigabit Ethernet Switch
Vitesse VSC7395 SparX-G5e 5+1-port Integrated Gigabit Ethernet Switch
Vitesse VSC7398 SparX-G8e 8-port Integrated Gigabit Ethernet Switch

These switches have a built-in 8051 CPU and can download and execute
firmware in this CPU. They can also be configured to use an external
CPU handling the switch in a memory-mapped manner by connecting to
that external CPU's memory bus.

This driver (currently) only takes control of the switch chip over
SPI and configures it to route packages around when connected to a
CPU port. The chip has embedded PHYs and VLAN support so we model it
using DSA as a best fit so we can easily add VLAN support and maybe
later also exploit the internal frame header to get more direct
control over the switch.

The four built-in GPIO lines are exposed using a standard GPIO chip.

      net: phy: vitesse: Add support for VSC73xx · 975ae7c6
      由 Linus Walleij 提交于 
      The VSC7385, VSC7388, VSC7395 and VSC7398 are integrated
switch/router chips for 5+1 or 8-port switches/routers. When
managed directly by Linux using DSA we need to do a special
set-up "dance" on the PHY. Unfortunately these sequences
switches the PHY to undocumented pages named 2a30 and 52b6
and does undocumented things. It is described by these opaque
sequences also in the reference manual. This is a best
effort to integrate it anyways.

====================
pull-request: bpf-next 2018-07-03

The following pull-request contains BPF updates for your *net-next* tree.

The main changes are:

1) Various improvements to bpftool and libbpf, that is, bpftool build
   speed improvements, missing BPF program types added for detection
   by section name, ability to load programs from '.text' section is
   made to work again, and better bash completion handling, from Jakub.

2) Improvements to nfp JIT's map read handling which allows for optimizing
   memcpy from map to packet, from Jiong.

3) New BPF sample is added which demonstrates XDP in combination with
   bpf_perf_event_output() helper to sample packets on all CPUs, from Toke.

4) Add a new BPF kselftest case for tracking connect(2) BPF hooks
   infrastructure in combination with TFO, from Andrey.

5) Extend the XDP/BPF xdp_rxq_info sample code with a cmdline option to
   read payload from packet data in order to use it for benchmarking.
   Also for '--action XDP_TX' option implement swapping of MAC addresses
   to avoid drops on some hardware seen during testing, from Jesper.
