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.

If you have a network (Ethernet) card belonging to this class, say Y.
|
|
|
|
Note that the answer to this question doesn't directly affect the
|
|
kernel: saying N will just cause the configurator to skip all
|
|
the questions about Solarflare devices. If you say Y, you will be asked
|
|
for your specific card in the following questions.

This driver supports 10/40-gigabit Ethernet cards based on
|
|
the Solarflare SFC9000-family and SFC9100-family controllers.
|
|
|
|
It also supports 10/25/40/100-gigabit Ethernet cards based
|
|
on the Solarflare EF100 networking IP in Xilinx FPGAs.
|
|
|
|
To compile this driver as a module, choose M here. The module
|
|
will be called sfc.

This exposes the on-board flash and/or EEPROM as MTD devices

driver/firmware interaction. The tracing is actually enabled by
|
|
a sysfs file 'mcdi_logging' under the PCI device.
