2021-07-27dev_ioctl: split out ndo_eth_ioctlArnd Bergmann
Most users of ndo_do_ioctl are ethernet drivers that implement the MII commands SIOCGMIIPHY/SIOCGMIIREG/SIOCSMIIREG, or hardware timestamping with SIOCSHWTSTAMP/SIOCGHWTSTAMP. Separate these from the few drivers that use ndo_do_ioctl to implement SIOCBOND, SIOCBR and SIOCWANDEV commands. This is a purely cosmetic change intended to help readers find their way through the implementation.

2020-09-07sfc: remove phy_op indirectionEdward Cree
Originally there were several implementations of PHY operations for the several different PHYs used on Falcon boards. But Falcon is now in a separate driver, and all sfc NICs since then have had MCDI-managed PHYs. Thus, there is no need to indirect through function pointers in efx->phy_op; we can simply call the efx_mcdi_phy_* functions directly. This also hooks up these functions for EF100, which was previously using the dummy_phy_ops. Signed-off-by: Edward Cree <ecree@solarflare.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2020-07-27sfc: skeleton EF100 PF driverEdward Cree
No TX or RX path, no MCDI, not even an ifup/down handler. Besides stubs, the bulk of the patch deals with reading the Xilinx extended PCIe capability, which tells us where to find our BAR. Though in the same module, EF100 has its own struct pci_driver, which is named sfc_ef100. A small number of additional nic_type methods are added; those in the TX (tx_enqueue) and RX (rx_packet) paths are called through indirect call wrappers to minimise the performance impact.

2020-07-25bpf, xdp: Remove XDP_QUERY_PROG and XDP_QUERY_PROG_HW XDP commandsAndrii Nakryiko
Now that BPF program/link management is centralized in generic net_device code, kernel code never queries program id from drivers, so XDP_QUERY_PROG/XDP_QUERY_PROG_HW commands are unnecessary. This patch removes all the implementations of those commands in kernel, along the xdp_attachment_query(). This patch was compile-tested on allyesconfig.

2020-07-23sfc: convert to new udp_tunnel infrastructureJakub Kicinski
Check MC_CMD_DRV_ATTACH_EXT_OUT_FLAG_TRUSTED, before setting the info, which will hopefully protect us from -EPERM errors the previous code was gracefully ignoring. Ed reports this is not the 100% correct bit, but it's the best approximation we have. Shared code reports the port information back to user space, so we really want to know what was added and what failed. Ignoring -EPERM is not an option. The driver does not call udp_tunnel_get_rx_info(), so its own management of table state is not really all that problematic, we can leave it be. This allows the driver to continue with its copious table syncing, and matching the ports to TX frames, which it will reportedly do one day. Leave the feature checking in the callbacks, as the device may remove the capabilities on reset. Inline the loop from __efx_ef10_udp_tnl_lookup_port() into efx_ef10_udp_tnl_has_port(), since it's the only caller now. With new infra this driver gains port replace - when space frees up in a full table a new port will be selected for offload. Plus efx will no longer sleep in an atomic context. v2: - amend the commit message about TRUSTED not being 100% - add TUNNEL_ENCAP_UDP_PORT_ENTRY_INVALID to mark unsed entries Signed-off-by: Jakub Kicinski <kuba@kernel.org> Acked-By: Edward Cree <ecree@solarflare.com> Signed-off-by: David S.

2020-07-02sfc: move modparam 'rss_cpus' out of common channel codeEdward Cree
Instead of exposing this old module parameter on the new driver (thus having to keep it forever after for compatibility), let's confine it to the old one; if we find later that we need the feature, we ought to support it properly, with ethtool set-channels.

2020-07-02sfc: move modparam 'interrupt_mode' out of common channel codeEdward Cree
EF100 only supports MSI-X, so there's no need for the new driver to expose this old module parameter.

If calling efx_ef10_mac_reconfigure() from efx_change_mtu(), and the NIC supports the above (SET_MAC_ENHANCED capability), use it rather than efx_mcdi_set_mac().

2019-11-22sfc: do ARFS expiry work occasionally even without NAPI pollEdward Cree
If there's no traffic on a channel, its ARFS expiry work will never get scheduled by efx_poll() as that isn't being run. So make efx_filter_rfs_expire() reschedule itself to run after 30 seconds.

2019-11-22sfc: change ARFS expiry mechanismEdward Cree
The old rfs_filters_added method for determining the quota could potentially allow the NIC to become filled with old filters, which never get tested for expiry. Instead, explicitly make expiry check work depend on the number of filters installed, and don't count checking slots without filters in as doing work. This guarantees that each filter will be checked for expiry at least once every thirty seconds (assuming the channel to which it belongs is NAPI polling actively) regardless of fill level.

2019-10-31sfc: allocate channels for XDP tx queuesCharles McLachlan
Each CPU needs access to its own queue to allow uncontested transmission of XDP_TX packets. This means we need to allocate (up front) enough channels ("xdp transmit channels") to provide at least one extra tx queue per CPU. These tx queues should not do TSO.
