    "content": "From: Alan Brady <alan.brady@intel.com>\n\nBroadcast filters can now cause overflow promiscuous to trigger when\nadding \"too many\" VLANs to all the ports of a device and the driver\nneeds a way to exit overflow promiscuous once triggered.\n\nCurrently the driver looks to see if there are \"too many\" filters and/or\nwe have any failed filters to determine when it is safe to exit overflow\npromiscuous.  If we trigger overflow promiscuous with broadcast filters,\nany new filters added will be \"auto-failed\" until we exit overflow\npromiscuous.  Since the user can't manually remove the failed broadcast\nfilters for VLANs (nor should we expect the user to do such), there is\nno way to exit overflow promiscuous without reloading the driver.\n\nThe easiest way to do this is to remove the shortcut to \"auto-fail\"\nfilters in overflow promscuous.  If the user removes the VLANs, the\nfailed filters will be removed and since we're no longer \"auto-failing\"\nnew filters, we'll eventually get a good set of filters and exit\noverflow promiscuous.\n\nThis has the side benefit of making filter state more explicit in that\nif a filter says it's failed we know for a fact it failed and not just\nassuming it will if we're in overflow promiscuous.  This is nice because\nif the user removes some filters and then adds some, even if we're in\noverflow promiscuous, the filter might succeed; we were just assuming it\nwon't because the user hasn't rectified other existing failed filters.\n\nSigned-off-by: Alan Brady <alan.brady@intel.com>\n---\n drivers/net/ethernet/intel/i40e/i40e_main.c | 15 +--------------\n 1 file changed, 1 insertion(+), 14 deletions(-)",
