Sean Wang says: ==================== net-next: dsa: add Mediatek MT7530 support MT7530 is a 7-ports Gigabit Ethernet Switch that could be found on Mediatek router platforms such as MT7623A or MT7623N which includes 7-port Gigabit Ethernet MAC and 5-port Gigabit Ethernet PHY. Among these ports, The port from 0 to 4 are the user ports connecting with the remote devices while the port 5 and 6 are the CPU ports connecting into Mediatek Ethernet GMAC. The patch series integrated Mediatek MT7530 into DSA support which includes the most of the essential callbacks such as tag insertion for port distinguishing, port control, bridge offloading, STP setup and ethtool operations to allow DSA to model each user port into independently standalone netdevice as the other DSA driver had done. Changes since v1: - rebased into 4.11-rc1 - refined binding document including below five items - changed the type of mediatek,mcm into bool - used reset controller binding for MCM reset and removed "mediatek,ethsys" property from binding - reused CPU port's ethernet Phandle instead of creating new one and removed "mediatek,ethernet" property from binding - aligned naming for GPIO reset with dsa/marvell.txt - added phy-mode as required property child nodes within ports container - handled gpio reset with devm_gpiod_* API - refined comment words - removed condition for CDM setting since the setup looks both fine for all cases - allowed of_find_net_device_by_node() working with pointing the device node into real netdev instance - fixed Kbuild warnings Changes since v2: - reuse readx_poll_timeout() to poll - add proper macro instead of hard coding - treat inconsistent cpu port as warning - remove the usage for regmap-debugfs - show error message when invalid id is found - put the logic for the setup of trgmii into adjut_link() - refine and reuse logic between port_[disable,enable], and default port setup - correct typo Changes since v3: - used struct as the parameter for readx_poll_timeout() and kill extra lpriv defined - moved around function to get out of an additional declaration - fixed kbuild errors caused by missing proper include in the latest tree ==================== Signed-off-by: -

MT7530 is a 7-ports Gigabit Ethernet Switch that could be found on Mediatek router platforms such as MT7623A or MT7623N platform which includes 7-port Gigabit Ethernet MAC and 5-port Gigabit Ethernet PHY. Among these ports, The port from 0 to 4 are the user ports connecting with the remote devices while the port 5 and 6 are the CPU ports connecting into Mediatek Ethernet GMAC. For port 6, it can communicate with the CPU via Mediatek Ethernet GMAC through either the TRGMII or RGMII which could be controlled by phy-mode in the dt-bindings to specify which mode is preferred to use. And for port 5, only RGMII can be specified. However, currently, only port 6 is being supported in this DSA driver. The driver is made with the reference to qca8k and other existing DSA driver. The most of the essential callbacks of the DSA are already support in the driver, including tag insert for user port distinguishing, port control, bridge offloading, STP setup and ethtool operation to allow DSA to model each user port into a standalone netdevice as the other DSA driver had done.

the patch adds the setup of the corresponding device node of GMAC into the netdev instance which could allow other modules such as DSA to find the instance through the node in dt-bindings using of_find_net_device_by_node() call. Signed-off-by:

The patch adds the setup for allowing CDM can recognize these packets with carrying port-distinguishing tag. Otherwise, these tagging packets will be handled incorrectly by CDM. The setup is also working out for general untag packets as well. Signed-off-by:

inet_rtm_getroute synthesizes a skeletal ICMP skb, which is passed to ip_route_input when iif is given. If a multipath route is present for the designated destination, fib_multipath_hash ends up being called with that skb. However, as that skb contains no information beyond the protocol type, the calculated hash does not match the one we would see for a real packet. There is currently no way to fix this for layer 4 hashing, as RTM_GETROUTE doesn't have the necessary information to create layer 4 headers. To fix this for layer 3 hashing, set appropriate saddr/daddrs in the skb and also change the protocol to UDP to avoid special treatment for ICMP. Signed-off-by:

Yuval Mintz says: ==================== qede: support XDP head adjustments Daniel has brought to my attention the fact that qede is the only driver that currently supports XDP but still fails any program where xdp_adjust_head is set on the bpf_prog. This series is meant to remedy this and align qede with the rest of the driver, making it possible to remove said field. Patch #1 contains a minor cache-saving optimization for latter patches. Patches #2 & #3 address existing issues with the qede implementation [#2 should have been a part of this as it addresses something that's affected by the additional headroom; #3 is simply here for the ride]. Patches #4 & #5 add the necessary logic in driver for ingress headroom, the first adding the infrastrucutre needed for supporting the headroon [as currently qede doesn't support such], and the second removing the existing XDP limitation. ==================== Signed-off-by: -
Mintz, Yuval authored
In case an XDP program is attached, reserve XDP_PACKET_HEADROOM bytes at the beginning of the packet for the program to play with. Modify the XDP logic in the driver to fill-in the missing bits and re-calculate offsets and length after the program has finished running to properly reflect the current status of the packet. We can then go and remove the limitation of not supporting XDP programs where xdp_adjust_head is set. Signed-off-by:

Driver currently doesn't support any headroom; The only 'available' space it has in the head of the buffer is due to the placement offset. In order to allow [later] support of XDP adjustment of headroom, modify the the ingress flow to properly handle a scenario where the packets would have such. Signed-off-by:

Mintz, Yuval authored
Current implementation of VFs is very tight in regard to queue resources. VFs support for XDP would require quite a bit of additional infrastructure in qede and qed [sharing of queue-zones between queues, more VF cids, mapping of the doorbell bar, etc.]. For now, prevent XDP programs from being attached to VFs. Signed-off-by:

Mintz, Yuval authored
Driver is currently using dma_unmap_single() with the address it passed to device for the purpose of forwarding, but the XDP transmission buffer was originally a page allocated for the rx-queue. The mapped address is likely to differ from the original mapped address due to the placement offset. This difference is going to get even bigger once we support headroom. Cache the original mapped address of the page, and use it for unmapping of the buffer when completion arrives for the XDP forwarded packet. Signed-off-by:

Mintz, Yuval authored
Currently, each time an ingress packet is passed to networking stack the driver increments a per-queue SW statistic. As we want to have additional fields in the first cache-line of the Rx-queue struct, change flow so this statistic would be updated once per NAPI run. We will later push the statistic to a different cache line. Signed-off-by:
