41e3b0722f sfc: introduce shutdown entry point in efx pci driver
Make the device inactive when the system shutdown callback has been
invoked. This is achieved by freezing the driver and disabling the
PCI bus mastering.

f029c781dd net: ethernet: move from strlcpy with unused retval to strscpy
Follow the advice of the below link and prefer 'strscpy' in this
subsystem. Conversion is 1:1 because the return value is not used.

c374303969 sfc/siena: Reinstate SRIOV init/fini function calls
They were removed in the first series since they were not used for EF10.
Put that code back for Siena, with the prototypes in siena_sriov.h
since that file is a more applicable place for it.

c8443b6982 sfc/siena: Rename functions in nic_common.h to avoid conflicts with sfc
For siena use efx_siena_ as the function prefix.
efx_nic_update_stats_atomic is only used in efx_common.c, so move
it there.
efx_nic_copy_stats is not used in Siena, so it is removed.

Some functions in ptp.c can also become static.
Rename loopback_mode in net_driver.h.

7f9e4b2a61 sfc/siena: Rename RX/TX functions to avoid conflicts with sfc
For siena use efx_siena_ as the function prefix.
Several functions are not used in Siena, so they are removed.

Use a Siena specific variable name for module parameter
efx_separate_tx_channels.
Move efx_fini_tx_queue() to avoid a forward declaration of
efx_dequeue_buffer().

71ad88f661 sfc/siena: Rename functions in efx headers to avoid conflicts with sfc
When building with allyesconfig there are many identical
symbol names.
For siena use efx_siena_ as the function and variable prefix
to avoid build errors.

efx_mtd_remove_partition can become static as it is no longer called
from other files.
efx_ticks_to_usecs and efx_xmit_done_single are not used in Siena, so
they are removed.
Several functions are only used inside efx_channels.c for Siena so
they can become static.

956f2d86cb sfc/siena: Remove build references to missing functionality
Functionality not supported or needed on Siena includes:
- Anything for EF100
- EF10 specifics such as register access, PIO and TSO offload.
Also only bind to Siena NICs.

Remove EF10 specifics from nic.h.
The functions that start with efx_farch_ will be removed from sfc.ko
with a subsequent patch.
Add the efx_ prefix to siena_prepare_flush() to make it consistent
with the other APIs.
