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.

sfc: factor out efx_tx_tso_header_length() and understand encapsulation

2020-06-30T20:09:09Z

ef100 will need to check this against NIC limits. Signed-off-by: Edward Cree Signed-off-by: David S. Miller

sfc: commonise TSO fallback code

2020-06-30T20:09:09Z

ef100 will need this if it gets GSO skbs it can't handle (e.g. too long header length). Signed-off-by: Edward Cree Signed-off-by: David S. Miller

sfc: complete the next packet when we receive a timestamp

2020-03-05T22:56:57Z

We now ignore the "completion" event when using tx queue timestamping, and only pay attention to the two (high and low) timestamp events. The NIC will send a pair of timestamp events for every packet transmitted. The current firmware may merge the completion events, and it is possible that future versions may reorder the completion and timestamp events. As such the completion event is not useful. Without this patch in place a merged completion event on a queue with timestamping will cause a "spurious TX completion" error. This affects SFN8000-series adapters.

The code that handles transmission finalization will also be common. Signed-off-by: Alexandru-Mihai Maftei Signed-off-by: David S. Miller

sfc: add new headers in preparation for code split

2020-01-08T21:28:02Z

New headers contain prototypes of functions that will be common between ef10 and upcoming driver. Removed static modifier from the affected functions. Some function prototypes were removed from existing headers. Signed-off-by: Alexandru-Mihai Maftei Signed-off-by: David S. Miller
