Re: [PATCH net-next] sfc: add missing prototypes for ef10 helper functions

From: chenaibing <redacted>

Fix the following W=1 warnings when building with -Wmissing-prototypes:

  drivers/net/ethernet/sfc/ef10.c: warning: no previous prototype for
  'efx_ef10_vadaptor_query' [-Wmissing-prototypes]
  drivers/net/ethernet/sfc/ef10.c: warning: no previous prototype for
  'efx_ef10_vadaptor_alloc' [-Wmissing-prototypes]
  drivers/net/ethernet/sfc/ef10.c: warning: no previous prototype for
  'efx_ef10_vadaptor_free' [-Wmissing-prototypes]
  drivers/net/ethernet/sfc/ef10.c: warning: no previous prototype for
  'efx_ef10_vport_add_mac' [-Wmissing-prototypes]
  drivers/net/ethernet/sfc/ef10.c: warning: no previous prototype for
  'efx_ef10_vport_del_mac' [-Wmissing-prototypes]
  drivers/net/ethernet/sfc/ef10.c: warning: no previous prototype for
  'efx_ef10_tx_tso_desc' [-Wmissing-prototypes]

These non-static functions are defined in ef10.c and called from
ef10_sriov.c, but have no declaration in any shared header.
Add the missing prototypes to efx.h.
