2022-11-25net: lan966x: Add support for XDP_REDIRECTHoratiu Vultur
Extend lan966x XDP support with the action XDP_REDIRECT. This is similar with the XDP_TX, so a lot of functionality can be reused. Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2022-11-25net: lan966x: Add support for XDP_TXHoratiu Vultur
Extend lan966x XDP support with the action XDP_TX. In this case when the received buffer needs to execute XDP_TX, the buffer will be moved to the TX buffers. So a new RX buffer will be allocated. When the TX finish with the frame, it would give back the buffer to the page pool. Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2022-11-25net: lan966x: Update dma_dir of page_pool_paramsHoratiu Vultur
To add support for XDP_TX it is required to be able to write to the DMA area therefore it is required that the pages will be mapped using DMA_BIDIRECTIONAL flag. Therefore check if there are any xdp programs on the interfaces and in that case set DMA_BIDRECTIONAL otherwise use DMA_FROM_DEVICE. Therefore when a new XDP program is added it is required to redo the page_pool. Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2022-11-25net: lan966x: Update rxq memory modelHoratiu Vultur
By default the rxq memory model is MEM_TYPE_PAGE_SHARED but to be able to reuse pages on the TX side, when the XDP action XDP_TX it is required to update the memory model to PAGE_POOL. Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2022-11-25net: lan966x: Add len field to lan966x_tx_dcb_bufHoratiu Vultur
Currently when a frame was transmitted, it is required to unamp the frame that was transmitted. The length of the frame was taken from the transmitted skb. In the future we might not have an skb, therefore store the length skb directly in the lan966x_tx_dcb_buf and use this one to unamp the frame. While at this, also arrange the members in lan966x_tx_dcb_buf not to have any holes. Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Introduce lan966x_fdma_tx_setup_dcb and lan966x_fdma_tx_start functions and use of them inside lan966x_fdma_xmit. There is no functional change in here. They are introduced to be used when XDP_TX/REDIRECT actions are introduced. Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2022-11-25net: lan966x: Add XDP_PACKET_HEADROOMHoratiu Vultur

2022-11-25net: microchip: sparx5: Support for TC protocol allSteen Hegelund
This allows support of TC protocol all for the Sparx5 IS2 VCAP. This is done by creating multiple rules that covers the rule size and traffic types in the IS2. Each rule size (e.g X16 and X6) may have multiple keysets and if there are more than one the type field in the VCAP rule will be wildcarded to support these keysets.

This adds API methods to set and get a rule counter. A VCAP instance may contain the counter as part of the VCAP cache area, and this counter may be one or more bits in width. This type of counter automatically increments it value when the rule is hit. Other VCAP instances have a dedicated counter area outside of the VCAP and in this case the rule must contain the counter id to be able to locate the counter value. In this case there must also be a rule action that updates the counter using the rule id when the rule is hit. The Sparx5 IS2 VCAP uses a dedicated counter area.

Here is an example: tc filter add dev eth12 ingress chain 8000000 prio 10 handle 10 \ protocol 0xbeef flower skip_sw \ dst_mac 0a:0b:0c:0d:0e:0f \ src_mac 2:0:0:0:0:1 \ action trap action goto chain 81000000 - The VLAN rules use classified VLAN information, and to get the classification information into the frame metadata, the ingress port need to be added to a bridge with the VID and vlan filtering enabled, like this (using VID 600 and four ports eth12, eth13, eth14 and eth15): ip link add name br5 type bridge ip link set dev br5 up ip link set eth12 master br5 ip link set eth13 master br5 ip link set eth14 master br5 ip link set eth15 master br5 sysctl -w net.ipv6.conf.eth12.disable_ipv6=1 sysctl -w net.ipv6.conf.eth13.disable_ipv6=1 sysctl -w net.ipv6.conf.eth14.disable_ipv6=1 sysctl -w net.ipv6.conf.eth15.disable_ipv6=1 sysctl -w net.ipv6.conf.br5.disable_ipv6=1 ip link set dev br5 type bridge vlan_filtering 1 bridge vlan add dev eth12 vid 600 bridge vlan add dev eth13 vid 600 bridge vlan add dev eth14 vid 600 bridge vlan add dev eth15 vid 600 bridge vlan add dev br5 vid 600 self Signed-off-by: Steen Hegelund <steen.hegelund@microchip.com> Tested-by: Casper Andersson <casper.casan@gmail.com> Signed-off-by: David S.

This changes the port keyset configuration for Sparx5 IS2 so that - IPv4 generates a IP4_TCP_UDP keyset for IPv4 TCP/UDP frames and a IP4_OTHER keyset for other IPv4 frames (both UC and MC) - IPv6 generates a IP_7TUPLE keyset (both UC and MC) ARP and non-IP traffic continues to generate the MAC_ETYPE keyset Signed-off-by: Steen Hegelund <steen.hegelund@microchip.com> Signed-off-by: David S.

2022-11-07net: remove explicit phylink_generic_validate() referencesRussell King (Oracle)
Virtually all conventional network drivers are now converted to use phylink_generic_validate() - only DSA drivers and fman_memac remain, so lets remove the necessity for network drivers to explicitly set this member, and default to phylink_generic_validate() when unset. This is possible as .validate must currently be set. Any remaining instances that have not been addressed by this patch can be fixed up later.
