efx_probe_all() calls efx->type->vswitching_probe during probe. For
SFC4000 (Falcon) NICs this function is not defined, leading to a BUG
with the top of the call stack similar to:
? efx_pci_probe_main+0x29a/0x830
efx_pci_probe+0x7d3/0xe70
vswitching_restore and vswitching_remove also need to be defined.
Fixed in mainline by:
commit 5a6681e22c ("sfc: separate out SFC4000 ("Falcon") support into new sfc-falcon driver")
Fixes: 6d8aaaf6f7 ("sfc: create VEB vswitch and vport above default firmware setup")
