2022-11-11net: microchip: sparx5: Adding more tc flower keys for the IS2 VCAPSteen Hegelund3-1/+396
This adds the following TC flower filter keys to Sparx5 for IS2: - ipv4_addr (sip and dip) - ipv6_addr (sip and dip) - control (IPv4 fragments) - portnum (tcp and udp port numbers) - basic (L3 and L4 protocol) - vlan (outer vlan tag info) - tcp (tcp flags) - ip (tos field) as well as an 128 bit keyfield interface on the VCAP API to set the IPv6 addresses. IS2 supports the classified VLAN information which amounts to the outer VLAN info in case of multiple tags. Here are some examples of the tc flower filter operations that are now supported for the IS2 VCAP: - IPv4 Addresses tc filter add dev eth12 ingress chain 8000000 prio 12 handle 12 \ protocol ip flower skip_sw dst_ip 1.0.1.1 src_ip 2.0.2.2 \ action trap action goto chain 81000000 - IPv6 Addresses tc filter add dev eth12 ingress chain 8000000 prio 13 handle 13 \ protocol ipv6 flower skip_sw dst_ip 1::1:1 src_ip 2::2:2 \ action trap action goto chain 81000000 - IPv4 fragments tc filter add dev eth12 ingress chain 8000000 prio 14 handle 14 \ protocol ip flower skip_sw dst_ip 3.0.3.3 src_ip 2.0.2.2 \ ip_flags frag/nofirstfrag action trap action goto chain 81000000 - TCP and UDP portnumbers tc filter add dev eth12 ingress chain 8000000 prio 21 handle 21 \ protocol ip flower skip_sw dst_ip 8.8.8.8 src_ip 2.0.2.2 \ ip_proto tcp dst_port 100 src_port 12000 action trap action goto chain 81000000 tc filter add dev eth12 ingress chain 8000000 prio 23 handle 23 \ protocol ipv6 flower skip_sw dst_ip 5::5:5 src_ip 2::2:2 \ ip_proto tcp dst_port 300 src_port 13000 action trap action goto chain 81000000 - Layer 3 and Layer 4 protocol info tc filter add dev eth12 ingress chain 8000000 prio 28 handle 28 \ protocol ipv4 flower skip_sw dst_ip 9.0.9.9 src_ip 2.0.2.2 \ ip_proto icmp action trap action goto chain 81000000 - VLAN tag info (outer tag) tc filter add dev eth12 ingress chain 8000000 prio 29 handle 29 \ protocol 802.1q flower skip_sw vlan_id 600 vlan_prio 6 \ vlan_ethtype ipv4 action trap action goto chain 81000000 tc filter add dev eth12 ingress chain 8000000 prio 31 handle 31 \ protocol 802.1q flower skip_sw vlan_id 600 vlan_prio 5 \ vlan_ethtype ipv6 action trap action goto chain 81000000 - TCP flags tc filter add dev eth12 ingress chain 8000000 prio 15 handle 15 \ protocol ip flower skip_sw dst_ip 4.0.4.4 src_ip 2.0.2.2 \ ip_proto tcp tcp_flags 0x2a/0x3f action trap action goto chain 81000000 - IP info (IPv4 TOS field) tc filter add dev eth12 ingress chain 8000000 prio 16 handle 16 \ protocol ip flower skip_sw ip_tos 0x35 dst_ip 5.0.5.5 \ src_ip 2.0.2.2 action trap action goto chain 81000000 Notes: - The "protocol all" selection is not supported yet. - The MAC address rule now needs to use non-ip and non "protocol all".

2022-11-01net: lan966x: Fix unmapping of received frames using FDMAHoratiu Vultur1-6/+12
When lan966x was receiving a frame, then it was building the skb and after that it was calling dma_unmap_single with frame size as the length. This actually has 2 issues: 1. It is using a length to map and a different length to unmap. 2. When the unmap was happening, the data was sync for cpu but it could be that this will overwrite what build_skb was initializing. The fix for these two problems is to change the order of operations. First to sync the frame for cpu, then to build the skb and in the end to unmap using the correct size but without sync the frame again for cpu.

2022-11-01net: lan966x: Fix FDMA when MTU is changedHoratiu Vultur2-3/+7
When MTU is changed, FDMA is required to calculate what is the maximum size of the frame that it can received. So it can calculate what is the page order needed to allocate for the received frames. The first problem was that, when the max MTU was calculated it was reading the value from dev and not from HW, so in this way it was missing L2 header + the FCS. The other problem was that once the skb is created using __build_skb_around, it would reserve some space for skb_shared_info. So if we received a frame which size is at the limit of the page order then the creating will failed because it would not have space to put all the data.

2022-10-24net: lan966x: Stop replacing tx dcbs and dcbs_buf when changing MTUHoratiu Vultur1-21/+3
When a frame is sent using FDMA, the skb is mapped and then the mapped address is given to an tx dcb that is different than the last used tx dcb. Once the HW finish with this frame, it would generate an interrupt and then the dcb can be reused and memory can be freed. For each dcb there is an dcb buf that contains some meta-data(is used by PTP, is it free). There is 1 to 1 relationship between dcb and dcb_buf. The following issue was observed. That sometimes after changing the MTU to allocate new tx dcbs and dcbs_buf, two frames were not transmitted. The frames were not transmitted because when reloading the tx dcbs, it was always presuming to use the first dcb but that was not always happening. Because it could be that the last tx dcb used before changing MTU was first dcb and then when it tried to get the next dcb it would take dcb 1 instead of 0. Because it is supposed to take a different dcb than the last used one. This can be fixed simply by changing tx->last_in_use to -1 when the fdma is disabled to reload the new dcb and dcbs_buff. But there could be a different issue. For example, right after the frame is sent, the MTU is changed. Now all the dcbs and dcbs_buf will be cleared. And now get the interrupt from HW that it finished with the frame. So when we try to clear the skb, it is not possible because we lost all the dcbs_buf. The solution here is to stop replacing the tx dcbs and dcbs_buf when changing MTU because the TX doesn't care what is the MTU size, it is only the RX that needs this information.

2022-10-24net: microchip: sparx5: Writing rules to the IS2 VCAPSteen Hegelund1-1/+425
This adds rule encoding functionality to the VCAP API. A rule consists of keys and actions in separate cache sections. The maximum size of the keyset or actionset determines the size of the rule. The VCAP hardware need to be able to distinguish different rule sizes from each other, and for that purpose some extra typegroup bits are added to the rule when it is encoded. The API provides a bit stream iterator that allows highlevel encoding functionality to add key and action value bits independent of typegroup bits. This is handled by letting the concrete VCAP model provide the typegroup table for the different rule sizes. After the key and action values have been added to the encoding bit streams the typegroup bits are set to their correct values just before the rule is written to the VCAP hardware. The key and action offsets provided in the VCAP model are the offset before adding the typegroup bits.

2022-10-24net: microchip: sparx5: Adding port keyset config and callback interfaceSteen Hegelund3-0/+431
This provides a default port keyset configuration for the Sparx5 IS2 VCAP where all ports and all lookups in IS2 use the same keyset (MAC_ETYPE) for all types of traffic. This means that no matter what frame type is received on any front port it will generate the MAC_ETYPE keyset in the IS VCAP and any rule in the IS2 VCAP that uses this keyset will be matched against the keys in the MAC_ETYPE keyset. The callback interface used by the VCAP API is populated with Sparx5 specific handler functions that takes care of the actual reading and writing to data to the Sparx5 IS2 VCAP instance. A few functions are also added to the VCAP API to support addition of rule fields such as the ingress port mask and the lookup bit. The IS2 VCAP in Sparx5 is really divided in two instances with lookup 0 and 1 in the first instance and lookup 2 and 3 in the second instance. The lookup bit selects lookup 0 or 3 in the respective instance when it is set.

The Sparx5 IS2 C code model is generated from the Sparx5 RTL design model. Signed-off-by: Steen Hegelund <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2022-10-24net: microchip: sparx5: Adding initial VCAP API supportSteen Hegelund9-2/+698
This provides the initial VCAP API framework and Sparx5 specific VCAP implementation. When the Sparx5 Switchdev driver is initialized it will also initialize its VCAP module, and this hooks up the concrete Sparx5 VCAP model to the VCAP API, so that the VCAP API knows what VCAP instances are available.

2022-10-20net: lan966x: Fix the rx drop counterHoratiu Vultur1-1/+9
Currently the rx drop is calculated as the sum of multiple HW drop counters. The issue is that not all the HW drop counters were added for the rx drop counter. So if for example you have a police that drops frames, they were not see in the rx drop counter. Fix this by updating how the rx drop counter is calculated. It is required to add also RX_RED_PRIO_* HW counters.

2022-10-03net: lan966x: Fix return type of lan966x_port_xmitNathan Huckleberry1-1/+2
The ndo_start_xmit field in net_device_ops is expected to be of type netdev_tx_t (*ndo_start_xmit)(struct sk_buff *skb, struct net_device *dev). The mismatched return type breaks forward edge kCFI since the underlying function definition does not match the function hook definition. The return type of lan966x_port_xmit should be changed from int to netdev_tx_t.

2022-10-03net: lan966x: Add port mirroring support using tc-matchallHoratiu Vultur5-1/+193
Add support for port mirroring. It is possible to mirror only one port at a time and it is possible to have both ingress and egress mirroring. Frames injected by the CPU don't get egress mirrored because they are bypassing the analyzer module. Signed-off-by: Horatiu Vultur <[email protected]> Signed-off-by: David S.
