The problem is fixed by changing the > maximum number of MAC address filters to 16+1+1 (two extra are needed > because the driver uses 1 for unicast MAC address and 1 for broadcast). > > Signed-off-by: Adam Ludkiewicz <adam.ludkiewicz@intel.com> > --- > drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c | 7 +++++-- > 1 file changed, 5 insertions(+), 2 deletions(-) Tested-by: Andrew Bowers <andrewx.bowers@intel.com>
