* net: dsa: Remove redundant phy_attach()Andrew Lunn2015-02-09
| | | | | | | | | | | | | | | | | dsa_slave_phy_setup() finds the phy for the port via device tree and using of_phy_connect(), or it uses the fall back of taking a phy from the switch internal mdio bus and calling phy_connect_direct(). Either way, if a phy is found, phy_attach_direct() is called to attach the phy to the slave device. In dsa_slave_create(), a second call to phy_attach() is made. This results in the warning "PHY already attached". Remove this second, redundant attaching of the phy.

* net: dsa: set slave MII bus PHY maskVivien Didelot2015-01-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When registering a mdio bus, Linux assumes than every port has a PHY and tries to scan it. If a switch port has no PHY registered, DSA will fail to register the slave MII bus. To fix this, set the slave MII bus PHY mask to the switch PHYs mask. As an example, if we use a Marvell MV88E6352 (which is a 7-port switch with no registered PHYs for port 5 and port 6), with the following declared names: static struct dsa_chip_data switch_cdata = { [...] .port_names[0] = "sw0", .port_names[1] = "sw1", .port_names[2] = "sw2", .port_names[3] = "sw3", .port_names[4] = "sw4", .port_names[5] = "cpu", }; DSA will fail to create the switch instance. With the PHY mask set for the slave MII bus, only the PHY for ports 0-4 will be scanned and the instance will be successfully created.

|/ | | | | | | | | | | | | | | | | | Setting skb->protocol to a private protocol type may result in warning messages such as e1000e 0000:00:19.0 em1: checksum_partial proto=dada! This happens if the L3 protocol is IP or IPv6 and skb->ip_summed is set to CHECKSUM_PARTIAL. Looking through the code, it appears that changing skb->protocol for transmitted packets is not necessary and may actually be harmful. For example, it prevents purposely unmodified (from a DSA perspective) network drivers from properly setting up their transmit checksum offload pointers since they inspect skb->protocol to set up the IPv4 header or IPv6 header pointers. So don't unnecessarily change the protocol field. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: David S. Miller <davem@davemloft.net>

* dsa: Split ops up, and avoid assigning tag_protocol and receive separatelyAlexander Duyck2014-09-15
| | | | | | | | | | | | | | | | | | | | | | | | This change addresses several issues. First, it was possible to set tag_protocol without setting the ops pointer. To correct that I have reordered things so that rcv is now populated before we set tag_protocol. Second, it didn't make much sense to keep setting the device ops each time a new slave was registered. So by moving the receive portion out into root switch initialization that issue should be addressed. Third, I wanted to avoid sending tags if the rcv pointer was not registered so I changed the tag check to verify if the rcv function pointer is set on the root tree. If it is then we start sending DSA tagged frames. Finally I split the device ops pointer in the structures into two spots. I placed the rcv function pointer in the root switch since this makes it easiest to access from there, and I placed the xmit function pointer in the slave for the same reason.

This is the case, if e.g: Port 1 of the switch is used and connects to a PHY at a MDIO address different than 1.

* net: dsa: reduce number of protocol hooksFlorian Fainelli2014-08-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

The xfrm6_output.c has a bug fix which overlaps the renaming of skb->local_df to skb->ignore_df. In the Altera TSE driver cases, the register access cleanups in net-next overlapped with bug fixes done in net. Similarly a bug fix to send ALB packets in the bonding driver using the right source address overlaps with cleanups in net-next. Signed-off-by: David S. Miller <davem@davemloft.net>
