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 5a6681e22c14 ("sfc: separate out SFC4000 ("Falcon") support into new sfc-falcon driver") Fixes: 6d8aaaf6f798 ("sfc: create VEB vswitch and vport above default firmware setup") Signed-off-by: Bert Kenward <bkenward@solarflare.com> --- drivers/net/ethernet/sfc/falcon.c | 10 ++++++++++ 1 file changed, 10 insertions(+)
