2020-02-27net: dsa: propagate resolved link config via mac_link_up()Russell King
Propagate the resolved link configuration down via DSA's phylink_mac_link_up() operation to allow split PCS/MAC to work. Tested-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-01-08net: dsa: Get information about stacked DSA protocolFlorian Fainelli
It is possible to stack multiple DSA switches in a way that they are not part of the tree (disjoint) but the DSA master of a switch is a DSA slave of another. When that happens switch drivers may have to know this is the case so as to determine whether their tagging protocol has a remove chance of working. This is useful for specific switch drivers such as b53 where devices have been known to be stacked in the wild without the Broadcom tag protocol supporting that feature. This allows b53 to continue supporting those devices by forcing the disabling of Broadcom tags on the outermost switches if necessary. The get_tag_protocol() function is therefore updated to gain an additional enum dsa_tag_protocol argument which denotes the current tagging protocol used by the DSA master we are attached to, else DSA_TAG_PROTO_NONE for the top of the dsa_switch_tree.

There is no need to set variable 'mbus' static since new value always be assigned before use it. Signed-off-by: Mao Wenan <maowenan@huawei.com> Reviewed-by: Oleksij Rempel <o.rempel@pengutronix.de> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-12-20net: dsa: add support for Atheros AR9331 built-in switchOleksij Rempel
Provide basic support for Atheros AR9331 built-in switch. So far it works as port multiplexer without any hardware offloading support.
