net: dsa: add support for the SMSC-LAN9303 tagging format

2017-04-20T17:48:54+00:00

To define the outgoing port and to discover the incoming port a regular
VLAN tag is used by the LAN9303. But its VID meaning is 'special'.

This tag handler/filter depends on some hardware features which must be
enabled in the device to provide and make use of this special VLAN tag
to control the destination and the source of an ethernet packet.

net: dsa: isolate legacy code

2017-04-17T15:03:17+00:00

This patch moves as is the legacy DSA code from dsa.c to legacy.c,
except the few shared symbols which remain in dsa.c.

net: dsa: Factor bottom tag receive functions

2017-04-08T20:49:36+00:00

All DSA tag receive functions do strictly the same thing after they have located
the originating source port from their tag specific protocol:

- push ETH_HLEN bytes
- set pkt_type to PACKET_HOST
- call eth_type_trans()
- bump up counters
- call netif_receive_skb()

Factor all of that into dsa_switch_rcv(). This also makes us return a pointer to
a sk_buff, which makes us symetric with the xmit function.

net-next: dsa: add Mediatek tag RX/TX handler

2017-04-07T20:50:55+00:00

Add the support for the 4-bytes tag for DSA port distinguishing inserted
allowing receiving and transmitting the packet via the particular port.
The tag is being added after the source MAC address in the ethernet
header.

net: break include loop netdevice.h, dsa.h, devlink.h

2017-03-29T05:46:04+00:00

There is an include loop between netdevice.h, dsa.h, devlink.h because
of NETDEV_ALIGN, making it impossible to use devlink structures in
dsa.h.

Break this loop by taking dsa.h out of netdevice.h, add a forward
declaration of dsa_switch_tree and netdev_set_default_ethtool_ops()
function, which is what netdevice.h requires.

No longer having dsa.h in netdevice.h means the includes in dsa.h no
longer get included. This breaks a few other files which depend on
these includes. Add these directly in the affected file.

net: dsa: check out-of-range ageing time value

2017-03-15T22:34:13+00:00

If a DSA switch driver cannot program an ageing time value due to it
being out-of-range, switchdev will raise a stack trace before failing.

To fix this, add ageing_time_min and ageing_time_max members to the
dsa_switch in order for the switch drivers to optionally specify their
supported ageing time limits.

The DSA core will now check for provided ageing time limits and return
-ERANGE from the switchdev prepare phase if the value is out-of-range.

net: dsa: remove unnecessary phy*.h includes

2017-02-10T18:51:04+00:00

Including phy.h and phy_fixed.h into net/dsa.h causes phy*.h to be an
unnecessary dependency for quite a large amount of the kernel.  There's
very little which actually requires definitions from phy.h in net/dsa.h
- the include itself only wants the declaration of a couple of
structures and IFNAMSIZ.

Add linux/if.h for IFNAMSIZ, declarations for the structures, phy.h to
mv88e6xxx.h as it needs it for phy_interface_t, and remove both phy.h
and phy_fixed.h from net/dsa.h.

This patch reduces from around 800 files rebuilt to around 40 - even
with ccache, the time difference is noticable.
