Additionally, the service task\nisn't scheduled to run automatically until the timer runs out. This\ncauses a needless delay of the first reset to begin talking to the\nswitch manager.\n\nWe can avoid this by simply not setting last_reset and immediately\nscheduling the service task while in probe. This allows the device to\nwake up faster, and avoids this delay.\n\nSigned-off-by: Jacob Keller <jacob.e.keller@intel.com>\n---\n drivers/net/ethernet/intel/fm10k/fm10k_pci.c | 6 ++----\n 1 file changed, 2 insertions(+), 4 deletions(-)", "diff": "diff --git a/drivers/net/ethernet/intel/fm10k/fm10k_pci.c b/drivers/net/ethernet/intel/fm10k/fm10k_pci.c\nindex 80b18f2479b4..32b5ace82cad 100644\n--- a/drivers/net/ethernet/intel/fm10k/fm10k_pci.c\n+++ b/drivers/net/ethernet/intel/fm10k/fm10k_pci.c\n@@ -1800,9 +1800,6 @@ static int fm10k_sw_init(struct fm10k_intfc *interface,\n \t\tnetdev->vlan_features |= NETIF_F_HIGHDMA;\n \t}\n \n-\t/* delay any future reset requests */\n-\tinterface->last_reset = jiffies + (10 * HZ);\n-\n \t/* reset and initialize the hardware so it is in a known state */\n \terr = hw->mac.ops.reset_hw(hw);\n \tif (err) {\n@@ -2079,8 +2076,9 @@ static int fm10k_probe(struct pci_dev *pdev, const struct pci_device_id *ent)\n \t/* enable SR-IOV after registering netdev to enforce PF/VF ordering */\n \tfm10k_iov_configure(pdev, 0);\n \n-\t/* clear the service task disable bit to allow service task to start */\n+\t/* clear the service task disable bit and kick off service task */\n \tclear_bit(__FM10K_SERVICE_DISABLE, interface->state);\n+\tfm10k_service_event_schedule(interface);\n \n \treturn 0;\n \n", "prefixes": [ "05/15" ] }
