Hello.
I've tried to build vanilla kernel (HEAD: 5c8a0fbb) and got the error:

  CC [M]  drivers/net/ethernet/intel/ixgbe/ixgbe_main.o
  drivers/net/ethernet/intel/ixgbe/ixgbe_main.c: In function 'ixgbe_set_interrupt_capability':
  drivers/net/ethernet/intel/ixgbe/ixgbe_main.c:4724:3: error: implicit declaration of function 'ixgbe_disable_sriov'
  drivers/net/ethernet/intel/ixgbe/ixgbe_main.c: In function 'ixgbe_remove':

Looks like the commit 9487dc84 breaks it when the CONFIG_PCI_IOV switched off.
