ixgbe: fix PHY link setup for 82599

2011-08-04T12:06:13Z

Fix pointer to setup_link for 82599. This resolves some link issues when advertising modes unsupported by the link partner. Signed-off-by: Emil Tantilov Tested-by: Phil Schmitt Signed-off-by: Jeff Kirsher

ixgbe: fix __ixgbe_notify_dca() bail out code

2011-08-04T12:03:27Z

The way __ixgbe_notify_dca() was currently set up it would not be possible to add a requester. Both cases of the IXGBE_FLAG_DCA_ENABLED bit being on and off would lead to the function exiting for a DCA_PROVIDER_ADD. Signed-off-by: Don Skidmore Tested-by: Phil Schmitt Signed-off-by: Jeff Kirsher

intel drivers: repair missing flush operations

2011-08-04T11:59:07Z

after review of all intel drivers, found several instances where drivers had the incorrect pattern of: memory mapped write(); delay(); which should always be: memory mapped write(); write flush(); /* aka memory mapped read */ delay(); explanation: The reason for including the flush is that writes can be held (posted) in PCI/PCIe bridges, but the read always has to complete synchronously and therefore has to flush all pending writes to a device. If a write is held and followed by a delay, the delay means nothing because the write may not have reached hardware (maybe even not until the next read) Signed-off-by: Jesse Brandeburg Tested-by: Aaron Brown Signed-off-by: Jeff Kirsher

ixgbe: convert to ndo_fix_features

2011-07-22T05:57:38Z

Private rx_csum flags are now duplicate of netdev->features & NETIF_F_RXCSUM. We remove those duplicates and now use the net_device_ops ndo_set_features. This was based on the original patch submitted by Michal Miroslaw . I also removed the special case not requiring a reset for X540 hardware. It is needed just as it is in 82599 hardware.

ixgbe: only enable WoL for magic packet by default

2011-07-22T05:57:15Z

Martin Wilck reported that systems using the ixgbe-driver that were capable of WoL were rebooting almost as soon as they were shut down. This is because the default WoL settings enabled magic packet, broadcast, unicast, and multicast. Other Intel devices seem to use the stored eeprom value for initial WoL capabilities. The 82578DM (e1000e) and 82576 (igb) the devices I looked at had only the magic packet enabled in the eeprom, so that seems appropriate on ixgbe-based devices as well. I set the WoL options on my 82578DM to be the same default as the ixgbe devices (umbg) and saw the same as Martin -- almost as soon as my box shutdown, it booted again. This patch changes the default to only be the magic packet. This is the same as the default for most Intel and non-Intel hardware currently upstream.

ixgbe: Pass staterr instead of re-reading status and error bits from descriptor

2011-07-22T05:56:37Z

This change is meant to address possible race conditions from the status and error bits on the RX descriptors being re-read by multiple functions in the RX cleanup path. To resolve this I have added code that will pass the staterr value to those functions. Signed-off-by: Alexander Duyck Tested-by: Ross Brattain Signed-off-by: Jeff Kirsher

ixgbe: Move interrupt related values out of ring and into q_vector

2011-07-22T05:56:17Z

This change moves work_limit, total_packets, and total_bytes into the ring container struct of the q_vector. The advantage of this is that it should reduce the size of memory used in the event of multiple rings being assigned to a single q_vector. In addition it should help to reduce the total workload for calculating itr since now total_packets and total_bytes will be the total work done of the interrupt instead of for the ring.

ixgbe: add structure for containing RX/TX rings to q_vector

2011-07-22T05:55:56Z

This patch adds support for a ring container structure to be used within the q_vector. The basic idea is to provide a means of separating the RX and TX rings while maintaining a common structure for their containment. The advantage to this is that later we should be able to pass this structure to the update_itr functions without needing to pass individual rings.
