From 4b732cd4bb6006ad7fd4d5cdba27fcb751cdf4b7 Mon Sep 17 00:00:00 2001 From: Paolo Abeni Date: Wed, 15 Jun 2016 15:37:59 +0200 Subject: ixgbe: napi_poll must return the work done Currently the function ixgbe_poll() returns 0 when it clean completely the rx rings, but this foul budget accounting in core code. Fix this returning the actual work done, capped to weight - 1, since the core doesn't allow to return the full budget when the driver modifies the napi status Signed-off-by: Paolo Abeni Reviewed-by: Venkatesh Srinivas Tested-by: Andrew Bowers Signed-off-by: Jeff Kirsher --- drivers/net/ethernet/intel/ixgbe/ixgbe_main.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/ethernet/intel/ixgbe/ixgbe_main.c b/drivers/net/ethernet/intel/ixgbe/ixgbe_main.c index 088c47cf27d9..8bebd862a54c 100644 --- a/drivers/net/ethernet/intel/ixgbe/ixgbe_main.c +++ b/drivers/net/ethernet/intel/ixgbe/ixgbe_main.c @@ -2887,7 +2887,7 @@ int ixgbe_poll(struct napi_struct *napi, int budget) if (!test_bit(__IXGBE_DOWN, &adapter->state)) ixgbe_irq_enable_queues(adapter, BIT_ULL(q_vector->v_idx)); - return 0; + return min(work_done, budget - 1); } /** -- cgit
