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: remove efx_ethtool_nway_reset()

2020-07-27T19:26:55Z

An MDIO-based n-way restart does not make sense for any of the NICs supported by this driver, nor for the coming EF100. Unlike on Falcon (which was already split off into a separate driver), the PHY on all of Siena, EF10 and EF100 is managed by MC firmware. While Siena can talk to the PHY over MDIO, doing so for anything other than debugging purposes (mdio_mii_ioctl) is likely to confuse the firmware. (According to the SFC firmware team, this support was originally added to the Siena driver early in the development of that product, before it was decided to have firmware manage the PHY.)

sfc: get drvinfo driver name from outside the common code

2020-07-02T21:47:40Z

Since ethtool_common.o will be built into both sfc and sfc_ef100 drivers, it can't use KBUILD_MODNAME directly. Instead, make it reference a string provided by the individual driver code. Signed-off-by: Edward Cree Signed-off-by: David S. Miller

sfc: commonise other ethtool bits

2020-06-30T00:37:48Z

A few more ethtool handlers which EF100 will share. Signed-off-by: Edward Cree Signed-off-by: David S. Miller

sfc: commonise ethtool NFC and RXFH/RSS functions

2020-06-30T00:37:48Z

EF100 will share EF10's model of filtering, hashing and spreading. Signed-off-by: Edward Cree Signed-off-by: David S. Miller

sfc: commonise ethtool link handling functions

2020-06-30T00:37:48Z

Link speeds, FEC, and autonegotiation are all things EF100 will share. Signed-off-by: Edward Cree Signed-off-by: David S. Miller

sfc: move some ethtool code
