ixgbe:add support for a new 82599 10G Base-T device

2010-05-21T06:07:06+00:00

This adds support for a new copper device for 82599, device id 0x151c. This 82599 10GBase-T device uses the PHY's internal temperature sensor to guard against over-temp conditions. In this scenario the PHY will be put in a low power mode and link will no longer be able to transmit or receive any data. When this occurs, the over-temp interrupt is latched and driver logs this error message. A HW reset or power cycle is required to clear this status.

ixgbe: Add support for VF MAC and VLAN configuration

2010-05-06T04:15:33+00:00

Add support for the "ip link set" and "ip link show" commands that allow configuration of the virtual functions' MAC and port VLAN via user space command line. Signed-off-by: Greg Rose Signed-off-by: Jeff Kirsher Signed-off-by: David S. Miller

ixgbe: disable MSI-X by default on certain Cisco adapters

2010-04-28T02:47:49+00:00

Due to an errata in 82598 parts MSI-X needs to be disabled in certain ixgbe devices designed to transfer peer-to-peer traffic on the PCIe bus. This patch sets the default interrupt type to MSI rather than MSI-X for specific Cisco ixgbe adapters.

ixgbe: cleanup maximum number of tx queues

2010-03-26T18:56:02+00:00

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: Add support for the new ethtool n-tuple programming interface

2010-02-11T04:03:14+00:00

This patch adds n-tuple filter programming to 82599. Signed-off-by: Peter P Waskiewicz Jr Signed-off-by: Jeff Kirsher Signed-off-by: David S. Miller

ixgbe: Make descriptor ring allocations NUMA-aware

2010-02-04T03:48:35+00:00

This patch allocates the ring structures themselves on each NUMA node along with the buffer_info structures. This way we don't allocate the entire ring memory on a single node in one big block, thus reducing NUMA node memory crosstalk.

ixgbe: Allocate driver resources per NUMA node

2010-02-04T03:48:35+00:00

The default policy for the current driver is to do all its memory allocation on whatever processor is running insmod/modprobe. This is less than optimal. This driver's default mode of operation will be to use each node for each subsequent transmit/receive queue. The most efficient allocation will be to then have the interrupts bound in such a way as to match up the interrupt of the queue to the cpu where its memory was allocated.

ixgbe: only process one ixgbe_watchdog_task at a time.

2010-02-04T03:39:56+00:00

Processing multiple ixgbe_watchdog_task calls may cause the link_up variable and IXGBE_FLAG_NEED_LINK_UPDATE flag to be set incorrectly. In the worse case this is causing the netif_carrier_off to be called inappropriately which results in an interface that can't be brought up. Although schedule_work() will only schedule the task if it is not already on the work queue the WORK_STRUCT_PENDING bits are cleared just before calling the work function. This allows WORK_STRUCT_PENDING to be cleared, the work function to start and meanwhile schedule another task. This patch adds a mutex to the watchdog task. This bug is actualized by changing DCB settings or doing extended cable pull or reset tests. Signed-off-by: John Fastabend Signed-off-by: Jeff Kirsher Signed-off-by: David S. Miller

ixgbe: Remove unused emulation MAC storage from the per VF data structure.

This data storage for SW emulated MAC addresses is unlikely to ever be used so pull it. Signed-off-by: Greg Rose Signed-off-by: Jeff Kirsher Signed-off-by: David S. Miller
