sfc: Remove more unused functions

2024-11-06T01:35:11Z

efx_ticks_to_usecs(), efx_reconfigure_port(), efx_ptp_get_mode(), and efx_tx_get_copy_buffer_limited() are unused. They seem to be partially due to the later splits to Siena, but some seem unused for longer. Remove them.

sfc: use new rxfh_context API

2024-06-29T01:53:21Z

The core is now responsible for allocating IDs and a memory region for us to store our state (struct efx_rss_context_priv), so we no longer need efx_alloc_rss_context_entry() and friends. Since the contexts are now maintained by the core, use the core's lock (net_dev->ethtool->rss_lock), rather than our own mutex (efx->rss_lock), to serialise access against changes; and remove the now-unused efx->rss_lock from struct efx_nic.

sfc: Remove support for siena high priority queue

2023-07-28T08:54:17Z

This also removes TC support code, since that was never supported for EF10. TC support for EF100 is not handled from efx.c. Signed-off-by: Martin Habets Acked-by: Edward Cree Signed-off-by: David S. Miller

sfc: attach/detach EF100 representors along with their owning PF

2022-07-22T11:50:06Z

Since representors piggy-back on the PF's queues for TX, they can only accept new TXes while the PF is up. Thus, any operation which detaches the PF must first detach all its VFreps. Signed-off-by: Edward Cree Signed-off-by: David S. Miller

sfc: Remove duplicate definition of efx_xmit_done

2022-04-12T10:13:30Z

It is defined both in efx.h and tx_common.h. Remove the definition in efx.h. Signed-off-by: Martin Habets Signed-off-by: Paolo Abeni

sfc: check hash is valid before using it

2020-08-14T21:07:16Z

On EF100, the RX hash field in the packet prefix may not be valid (e.g. if the header parse failed), and this is indicated by a one-bit flag elsewhere in the packet prefix. Only call skb_set_hash() if the RSS_HASH_VALID bit is set. Signed-off-by: Edward Cree Signed-off-by: David S. Miller

sfc: skeleton EF100 PF driver

2020-07-27T19:26:55Z

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.

EF100 will use the same approach to ARFS as EF10. Signed-off-by: Edward Cree Signed-off-by: David S. Miller
