2023-02-08nfp: ethtool: fix the bug of setting unsupported port speedYu Xiao2-36/+170
Unsupported port speed can be set and cause error. Now fixing it and return an error if setting unsupported speed. This fix depends on the following, which was included in v6.2-rc1: commit a61474c41e8c ("nfp: ethtool: support reporting link modes").

2023-02-08nfp: flower: add check for flower VF netdevs for get/set_eepromJames Hershaw1-6/+6
Move the nfp_net_get_port_mac_by_hwinfo() check to ahead in the get/set_eeprom() functions to in order to check for a VF netdev, which this function does not support. It is debatable if this is a fix or an enhancement, and we have chosen to go for the latter. It does address a problem introduced by commit 74b4f1739d4e ("nfp: flower: change get/set_eeprom logic and enable for flower reps"). However, the ethtool->len == 0 check avoids the problem manifesting as a run-time bug (NULL pointer dereference of app).

2023-02-03net: flow_offload: provision conntrack info in ct_metadataVlad Buslov1-0/+24
In order to offload connections in other states besides "established" the driver offload callbacks need to have access to connection conntrack info. Flow offload intermediate representation data structure already contains that data encoded in 'cookie' field, so just reuse it in the drivers. Reject offloading IP_CT_NEW connections for now by returning an error in relevant driver callbacks based on value of ctinfo. Support for offloading such connections will need to be added to the drivers afterwards. Signed-off-by: Vlad Buslov <vladbu@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2023-02-03drivers: net: turn on XDP featuresMarek Majtyka1-0/+5
A summary of the flags being set for various drivers is given below. Note that XDP_F_REDIRECT_TARGET and XDP_F_FRAG_TARGET are features that can be turned off and on at runtime. This means that these flags may be set and unset under RTNL lock protection by the driver. Hence, READ_ONCE must be used by code loading the flag value. Also, these flags are not used for synchronization against the availability of XDP resources on a device. It is merely a hint, and hence the read may race with the actual teardown of XDP resources on the device. This may change in the future, e.g. operations taking a reference on the XDP resources of the driver, and in turn inhibiting turning off this flag. However, for now, it can only be used as a hint to check whether device supports becoming a redirection target. Turn 'hw-offload' feature flag on for: - netronome (nfp) - netdevsim. Turn 'native' and 'zerocopy' features flags on for: - intel (i40e, ice, ixgbe, igc) - mellanox (mlx5). - stmmac - netronome (nfp) Turn 'native' features flags on for: - amazon (ena) - broadcom (bnxt) - freescale (dpaa, dpaa2, enetc) - funeth - intel (igb) - marvell (mvneta, mvpp2, octeontx2) - mellanox (mlx4) - mtk_eth_soc - qlogic (qede) - sfc - socionext (netsec) - ti (cpsw) - tap - tsnep - veth - xen - virtio_net.

This patch corrects two oversights relating to releasing resources and DCB initialisation. 1. If mapping of the dcbcfg_tbl area fails: an error should be propagated, allowing partial initialisation (probe) to be unwound. 2. Conversely, if where dcbcfg_tbl is successfully mapped: it should be unmapped in nfp_nic_dcb_clean() which is called via various error cleanup paths, and shutdown or removal of the PCIE device.

2023-01-27devlink: protect devlink param list by instance lockJiri Pirko2-7/+8
Commit 1d18bb1a4ddd ("devlink: allow registering parameters after the instance") as the subject implies introduced possibility to register devlink params even for already registered devlink instance. This is a bit problematic, as the consistency or params list was originally secured by the fact it is static during devlink lifetime. So in order to protect the params list, take devlink instance lock during the params operations. Introduce unlocked function variants and use them in drivers in locked context. Put lock assertions to appropriate places.

2023-01-25nfp: flower: change get/set_eeprom logic and enable for flower repsJames Hershaw1-4/+7
The changes in this patch are as follows: - Alter the logic of get/set_eeprom functions to use the helper function nfp_app_from_netdev() which handles differentiating between an nfp_net and a nfp_repr. This allows us to get an agnostic backpointer to the pdev. - Enable the various eeprom commands by adding the 'get_eeprom_len', 'get_eeprom', 'set_eeprom' callbacks to the nfp_port_ethtool_ops struct. This allows the eeprom commands to work on representor interfaces, similar to a previous patch which added it to the vnics. Currently these are being used to configure persistent MAC addresses for the physical ports on the nfp.

2023-01-13net: remove redundant config PCI dependency for some network driver configsLukas Bulwahn1-1/+1
While reviewing dependencies in some Kconfig files, I noticed the redundant dependency "depends on PCI && PCI_MSI". The config PCI_MSI has always, since its introduction, been dependent on the config PCI. So, it is sufficient to just depend on PCI_MSI, and know that the dependency on PCI is implicitly implied. Reduce the dependencies of some network driver configs. No functional change and effective change of Kconfig dependendencies.

Currently `sp_indiff` is cleaned when driver is removed. This will cause problem in multi-PF/multi-host case, considering one PF is removed while another is still in use. Since `sp_indiff` is the application firmware property, it should only be cleaned when the firmware is unloaded. Now let management firmware to clean it when necessary, driver only set it.
