* ixgbe: Do not run all Diagnostic offline tests when VFs are activeGreg Rose2010-03-271-0/+21
| | | | | | | | | | | | | | When running the offline diagnostic tests check to see if any VFs are online. If so then only run the link test. This is necessary because the VFs running in guest VMs aren't aware of when the PF is taken offline for a diagnostic test. Also put a message to the system log telling the system administrator to take the VFs offline manually if (s)he wants to run a full diagnostic. Return 1 on each of the tests not run to alert the user of the condition.

* e1000e: do not modify tx_queue_len on link speed changeEmil Tantilov2010-03-262-11/+1
| | | | | | | | | | | | | | Previously the driver tweaked txqueuelen to avoid false Tx hang reports seen at half duplex. This had the effect of overriding user set values on link change/reset. Testing shows that adjusting only the timeout factor is sufficient to prevent Tx hang reports at half duplex. This patch removes all instances of tx_queue_len in the driver.

* ixgbe: filter FIP frames into the FCoE offload queuesChris Leech2010-03-262-0/+16
| | | | | | | | | | | | | During FCF solicitation, the switch is supposed to pad the solicited advertisement out to the endpoints specified maximum FCoE frame size. That means that we need to receive FIP frames that are larger than the standard MTU. To make sure the receive queue is configured correctly, we should be filtering FIP traffic into the FCoE queues.

| | | | | | | | | | | | | | | | In the last patch I missed an unecessary min_t comparison. This patch removes it, the path allocates at most 72 tx queues for 82599 and 24 for 82598 there is no need for this check. Additionally this sets MAX_[TX|RX]_QUEUES to 72. Which is used as the size for the tx/rx_ring arrays. There is no reason to have more tx_rings/rx_rings then num_tx_queues.

* ixgbe: In SR-IOV mode insert delay before bring the adapter upGreg Rose2010-03-261-0/+8
| | | | | | | | | | | | | | | VFs running in guest VMs do not respond in as timely a manner to PF indication it is going down as they do when running in the host domain. If the adapter is in SR-IOV mode insert a two second delay to guarantee that all VFs have had time to respond to the PF reset. In any case resetting the PF while VFs are active should be discouraged but if it must be done then there will be a two second delay to help synchronize resets among the PF and all the VFs.

| | | | | | | | | | | | | | | The bnx2 driver calls netif_napi_add() for all the NAPI structs during ->probe() time but not all of them will be used if we're not in MSI-X mode. This creates a problem for netpoll since it will poll all the NAPI structs in the dev_list whether or not they are scheduled, resulting in a crash when we access structure fields not initialized for that vector. We fix it by moving the netif_napi_add() call to ->open() after the number of IRQ vectors has been determined.

They accumulate to the maximum value and then roll over. They are also not cleared when the VF executes a soft reset, so it is possible they are non-zero when the driver loads and starts. This has all been accounted for in the code that keeps the stats up to date but there is one case that is not. When the PF driver is reset the counters in the VF are all reset to zero. This adds an additional accounting overhead into the VF driver when the PF is reset under its feet. This patch adds additional counters that are used by the VF driver to accumulate and save stats after a PF reset has been detected. Prior to this patch displaying the stats in the VF after the PF has reset would show bogus data.

| * | | ixgbe: fix for real_num_tx_queues update issueVasu Dev2010-03-191-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently netdev_features_change is called before fcoe tx queues setup is done, so this patch moves calling of netdev_features_change after tx queues setup is done in ixgbe_init_interrupt_scheme, so that real_num_tx_queues is updated correctly on each fcoe enable or disable. This allows additional fcoe queues updated correctly in vlan driver for their correct queue selection.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TX checksum offload does not work properly when transmitting UDP packets with 0, 1 or 2 bytes of data. This patch works around the problem by calculating checksums for these packets in the driver. Signed-off-by: Steve Glendinning <steve.glendinning@smsc.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Advanced Power Management is disabled for 82599 KX4 connections by clearing GRC.APME bit, causing it to not wake the system from an improper system shutdown. By default GRC.APME is enabled and software is not supposed to clear these settings during adapter probe.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix 82599 link issues during driver load and unload test using multi-speed 10G & 1G fiber modules. When connected back to back sometime 82599 multispeed fiber modules would link at 1G speed instead of 10G highest speed, due to a race condition in autotry process involving Tx laser flapping. Move autotry autoneg-37 tx laser flapping process from multispeed module init setup to driver unload. This will alert the link partner to restart its autotry process when it tries to establish the link with the link partner Signed-off-by: Mallikarjuna R Chilakala <mallikarjuna.chilakala@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S.
