2011-10-12ixgbe: Correct check for change in FCoE priorityMark Rustad
Correct a check for change in FCoE priority when IEEE mode DCB is in use. In IEEE mode a different function has to be used to get the FCoE priority mask. Also, the check for the mask assumed that only one priority was set. In case there should be more than one, check just the bit. These changes help avoid link flapping issues that can come up when IEEE DCB is in use.

2011-10-12ixgbe: Add protection from VF invalid target DMAGreg Rose
It is possible for a VF to set an invalid target DMA address in its Tx/Rx descriptor buffer pointers. The workarounds in this patch will guard against such an event and issue a VFLR to the VF in response. The VFLR will shut down the VF until an administrator can take action to investigate the event and correct the problem.

2011-10-05ixgbe: get pauseparam autonegMika Lansirinne
There is a problem in the ixgbe driver with the reporting of the flow control parameters. The autoneg parameter is shown to be of if *either* it really is off, or current modes for both tx and rx are off. The problem is seen when the parameters are read or set when the link is down. In this case, the driver sees that tx and rx are currently off and therefore autoneg parameter is incorrectly reported to be off too. Also, the ethtool binary can not set the autoneg off since it sees that it already is. When a link later comes up, the autonegotiation is carried out normally and the driver later on reports the autoneg parameter to be on (as it is) and then it can also be changed with ethtool. The patch is made against v3.0 kernel, but the problem seems to be there since v2.6.30-rc1. Reviewer comments: What we are trying to do is to disable flow control while the cable is disconnected. Since ixgbe defaults to full flow control, we call ethtool -A autoneg off rx off tx off while the cable is disconnected. This doesn't work, because the driver sets hw->fc.current_mode = ixgbe_fc_none if the cable is unplugged. ixgbe_get_pauseparam() then reports to ethtool that nothing needs to be done. The code fixes this, but it might have some unknown consequences.

2011-09-28ixgbe: update {P}FC thresholds to account for X540 and loopbackJohn Fastabend
Revise high and low threshold marks wrt flow control to account for the X540 devices and latency introduced by the loopback switch. Without this it was in theory possible to drop frames on a supposedly lossless link with X540 or SR-IOV enabled. Previously we used a magic number in a define to calculate the threshold values. This made it difficult to sort out exactly which latencies were or were not being accounted for. Here I was overly explicit and tried to used #define names that would be recognizable after reading the IEEE 802.1Qbb specification.

This patch is meant to help cleanup the interrupt throttle rate logic by storing the interrupt throttle rate as a value in microseconds instead of interrupts per second.

It was possible to inadvertently add additional interrupt causes to the MSI-X other interrupt. This occurred when things such as RX buffer overrun events were being triggered at the same time as an event such as a Flow Director table reinit request. In order to avoid this we should be explicitly programming only the interrupts that we want enabled. In addition I am renaming the ixgbe_msix_lsc function and interrupt to drop any implied meaning of this being a link status only interrupt.
