2021-03-19net: ocelot: support multiple bridgesVladimir Oltean1-36/+36
The ocelot switches are a bit odd in that they do not have an STP state to put the ports into. Instead, the forwarding configuration is delayed from the typical port_bridge_join into stp_state_set, when the port enters the BR_STATE_FORWARDING state. I can only guess that the implementation of this quirk is the reason that led to the simplification of the driver such that only one bridge could be offloaded at a time. We can simplify the data structures somewhat, and introduce a per-port bridge device pointer and STP state, similar to how the LAG offload works now (there we have a per-port bonding device pointer and TX enabled state). This allows offloading multiple bridges with relative ease, while still keeping in place the quirk to delay the programming of the PGIDs. We actually need this change now because we need to remove the bogus restriction from ocelot_bridge_stp_state_set that ocelot->bridge_mask needs to contain BIT(port), otherwise that function is a no-op.

2021-03-19net: ocelot: Fix deletetion of MRP entries from MAC tableHoratiu Vultur1-2/+2
When a MRP ring was deleted or disabled, the driver was iterating over the ports to detect if any other MPR rings exists and in case it didn't exist it would delete the MAC table entry. But the problem was that it used the last iterated port to delete the MAC table entry and this could be a NULL port. The fix consists of using the port on which the function was called.

The MKEX profile describes what packet fields need to be extracted from the input packet and how to place those packet fields in the output key for MCAM matching. The MKEX profile can be in a way where higher layer packet fields can overwrite lower layer packet fields in output MCAM Key. Hence MKEX profile is always ensured that there are no overlaps between any of the layers. But the commit 42006910b5ea ("octeontx2-af: cleanup KPU config data") introduced TX TOS field which overlaps with DMAC in MCAM key. This led to AF driver returning error when TX rule is installed with DMAC as match criteria since DMAC gets overwritten and cannot be supported.

2021-03-18octeontx2-pf: Add tc flower hardware offload on ingress trafficNaveen Mamindlapalli6-2/+551
This patch adds support for tc flower hardware offload on ingress traffic. Since the tc-flower filter rules use the same set of MCAM rules as the n-tuple filters, the n-tuple filters and tc flower rules are mutually exclusive. When one of the feature is enabled using ethtool, the other feature is disabled in the driver. By default the driver enables n-tuple filters during initialization. The following flow keys are supported. -> Ethernet: dst_mac -> L2 proto: all protocols -> VLAN (802.1q): vlan_id/vlan_prio -> IPv4: dst_ip/src_ip/ip_proto{tcp|udp|sctp|icmp}/ip_tos -> IPv6: ip_proto{icmpv6} -> L4(tcp/udp/sctp): dst_port/src_port The following flow actions are supported. -> drop -> accept -> redirect -> vlan pop The flow action supports multiple actions when vlan pop is specified as the first action. The redirect action supports redirecting to the PF/VF of same PCI device. Redirecting to other PCI NIX devices is not supported. Example #1: Add a tc filter rule to drop UDP traffic with dest port 80 # ethtool -K eth0 hw-tc-offload on # tc qdisc add dev eth0 ingress # tc filter add dev eth0 protocol ip parent ffff: flower ip_proto \ udp dst_port 80 action drop Example #2: Add a tc filter rule to redirect ingress traffic on eth0 with vlan id 3 to eth6 (ex: eth0 vf0) after stripping the vlan hdr. # ethtool -K eth0 hw-tc-offload on # tc qdisc add dev eth0 ingress # tc filter add dev eth0 parent ffff: protocol 802.1Q flower \ vlan_id 3 vlan_ethtype ipv4 action vlan pop action mirred \ ingress redirect dev eth6 Example #3: List the ingress filter rules # tc -s filter show dev eth4 ingress Example #4: Delete tc flower filter rule with handle 0x1 # tc filter del dev eth0 ingress protocol ip pref 49152 \ handle 1 flower Signed-off-by: Naveen Mamindlapalli <naveenm@marvell.com> Signed-off-by: David S.

2021-03-18octeontx2-pf: Add ip tos and ip proto icmp/icmpv6 flow offload supportNaveen Mamindlapalli3-4/+57
Add support for programming the HW MCAM match key with IP tos, IP(v6) proto icmp/icmpv6, allowing flow offload rules to be installed using those fields. The NPC HW extracts layer type, which will be used as a matching criteria for different IP protocols. The ethtool n-tuple filter logic has been updated to parse the IP tos and l4proto for HW offloading. l4proto tcp/udp/sctp/ah/esp/icmp are supported. See example usage below. Ex: Redirect l4proto icmp to vf 0 queue 0 ethtool -U eth0 flow-type ip4 l4proto 1 action vf 0 queue 0 Ex: Redirect flow with ip tos 8 to vf 0 queue 0 ethtool -U eth0 flow-type ip4 tos 8 vf 0 queue 0 Signed-off-by: Naveen Mamindlapalli <naveenm@marvell.com> Signed-off-by: David S.

2021-03-18netsec: restore phy power state after controller resetMian Yousaf Kaukab1-3/+6
Since commit 8e850f25b581 ("net: socionext: Stop PHY before resetting netsec") netsec_netdev_init() power downs phy before resetting the controller. However, the state is not restored once the reset is complete. As a result it is not possible to bring up network on a platform with Broadcom BCM5482 phy. Fix the issue by restoring phy power state after controller reset is complete.

2021-03-18bpf, devmap: Move drop error path to devmap for XDP_REDIRECTLorenzo Bianconi17-142/+95
We want to change the current ndo_xdp_xmit drop semantics because it will allow us to implement better queue overflow handling. This is working towards the larger goal of a XDP TX queue-hook. Move XDP_REDIRECT error path handling from each XDP ethernet driver to devmap code. According to the new APIs, the driver running the ndo_xdp_xmit pointer, will break tx loop whenever the hw reports a tx error and it will just return to devmap caller the number of successfully transmitted frames. It will be devmap responsibility to free dropped frames. Move each XDP ndo_xdp_xmit capable driver to the new APIs: - veth - virtio-net - mvneta - mvpp2 - socionext - amazon ena - bnxt - freescale (dpaa2, dpaa) - xen-frontend - qede - ice - igb - ixgbe - i40e - mlx5 - ti (cpsw, cpsw-new) - tun - sfc Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Reviewed-by: Ioana Ciornei <ioana.ciornei@nxp.com> Reviewed-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Reviewed-by: Camelia Groza <camelia.groza@nxp.com> Acked-by: Edward Cree <ecree.xilinx@gmail.com> Acked-by: Jesper Dangaard Brouer <brouer@redhat.com> Acked-by: Shay Agroskin <shayagr@amazon.com> Link: https://lore.kernel.org/bpf/ed670de24f951cfd77590decf0229a0ad7fd12f6.1615201152.git.lorenzo@kernel.org
2021-03-18net: macb: simplify clk_init with dev_err_probeMichael Tretter1-11/+9
On some platforms, e.g., the ZynqMP, devm_clk_get can return -EPROBE_DEFER if the clock controller, which is implemented in firmware, has not been probed yet. As clk_init is only called during probe, use dev_err_probe to simplify the error message and hide it for -EPROBE_DEFER.
