ether: add IEEE 1722 ethertype - TSN

2015-09-10T05:06:29+00:00

IEEE 1722 describes AVB (later renamed to TSN - Time Sensitive
Networking), a protocol, encapsualtion and synchronization to utilize
standard networks for audio/video (and later other time-sensitive)
streams.

This standard uses ethertype 0x22F0.

This is a respin of a previous patch ("ether: add AVB frame type
ETH_P_AVB")

net: dsa: reduce number of protocol hooks

2014-08-28T05:59:39+00:00

DSA is currently registering one packet_type function per EtherType it
needs to intercept in the receive path of a DSA-enabled Ethernet device.
Right now we have three of them: trailer, DSA and eDSA, and there might
be more in the future, this will not scale to the addition of new
protocols.

This patch proceeds with adding a new layer of abstraction and two new
functions:

dsa_switch_rcv() which will dispatch into the tag-protocol specific
receive function implemented by net/dsa/tag_*.c

dsa_slave_xmit() which will dispatch into the tag-protocol specific
transmit function implemented by net/dsa/tag_*.c

When we do create the per-port slave network devices, we iterate over
the switch protocol to assign the DSA-specific receive and transmit
operations.

A new fake ethertype value is used: ETH_P_XDSA to illustrate the fact
that this is no longer going to look like ETH_P_DSA or ETH_P_TRAILER
like it used to be.

This allows us to greatly simplify the check in eth_type_trans() and
always override the skb->protocol with ETH_P_XDSA for Ethernet switches
tagged protocol, while also reducing the number repetitive slave
netdevice_ops assignments.

ether: add loopback type ETH_P_LOOPBACK

2014-03-15T02:20:57+00:00

Per IEEE 802.3*, the correct packet type for loopback 0x9000. There's
already one ETH_P_LOOP 0x0060, which has been there for ages, however it's
plainly wrong as anything that small is considered a length field.

We can't remove it because legacy, so add a new type which corresponds to
the correct id.

net: order MPLS ethertypes numerically

2014-02-26T20:14:26+00:00

All ethertypes other than ETH_P_MPLS_UC, ETH_P_MPLS_MC and
ETH_P_ATMMPOA were already ordered numerically.  This commit moves
those three ETH_P_... values into correct numerical order too.

net/hsr: Add support for the High-availability Seamless Redundancy protocol (HSRv0)

2013-11-04T04:20:14+00:00

High-availability Seamless Redundancy ("HSR") provides instant failover
redundancy for Ethernet networks. It requires a special network topology where
all nodes are connected in a ring (each node having two physical network
interfaces). It is suited for applications that demand high availability and
very short reaction time.

HSR acts on the Ethernet layer, using a registered Ethernet protocol type to
send special HSR frames in both directions over the ring. The driver creates
virtual network interfaces that can be used just like any ordinary Linux
network interface, for IP/TCP/UDP traffic etc. All nodes in the network ring
must be HSR capable.

This code is a "best effort" to comply with the HSR standard as described in
IEC 62439-3:2010 (HSRv0).

net: add ETH_P_802_3_MIN

2013-03-28T05:20:42+00:00

Add a new constant ETH_P_802_3_MIN, the minimum ethernet type for
an 802.3 frame. Frames with a lower value in the ethernet type field
are Ethernet II.

Also update all the users of this value that David Miller and
I could find to use the new constant.

Also correct a bug in util.c. The comparison with ETH_P_802_3_MIN
should be >= not >.

As suggested by Jesse Gross.

Compile tested only.

if_ether.h: add B.A.T.M.A.N.-Advanced Ethertype

2012-11-03T19:05:25+00:00

Add Ethertype 0x4305 (not an officially registered id).
This Ethertype is used by every frame generated by B.A.T.M.A.N.-Advanced. Its
definition is currently batman-adv local only and since it is not officially
registered it is better to make its definition kernel-wide so that we avoid
collisions given by future unofficial uses of the same Ethertype.
