Originally ixgbe_device_supports_autoneg_fc() was only expected to be called by copper devices. This would lead to false information to be displayed via ethtool. v2: changed ixgbe_device_supports_autoneg_fc() to a bool function, it returns bool.

This patch enables ethtool to correctly identify flow control (pause frame) auto negotiation, as well as disallow enabling it when it is not supported. The ixgbe_device_supports_autoneg_fc function is exported and used for this purpose. There is also one minor cleanup of the device_supports_autoneg_fc by removing an unnecessary return statement.

The current logic is enabling anti-spoof on all pools and then clearing anti-spoof on just the first PF pool. The correct approach is to only set anti-spoof on the VF pools and to leave all of the PF pools unchecked. This allows for items such as FCoE to use adjacent pools within the PF for transmit and receive queues without the traffic being blocked by this security feature.

This change corrects an issue in which an FCoE enabled adapter was always setting the FCoE SAN MAC MPSAR register to 0x1. This results in the first VF being assigned the SAN MAC address in the case of SR-IOV and as such is incorrect.

This change updates the link flow control configuration so that we correctly set the link flow control settings for DCB. Previously we would have to call the fc_enable call 8 times, once for each packet buffer. If we move that logic into the fc_enable call itself we can avoid multiple unnecessary register writes. This change also corrects an issue in which we were only shifting the water marks for 82599 parts by 6 instead of 10. This was resulting in us only using 1/16 of the packet buffer when flow control was enabled.

This change makes it so that ixgbe_fc_autoneg is a void and always sets the current_mode. Previously if the link was down we would return an error, however there is no harm in simply treating a link down case as a case in which autoneg simply failed. This allows us to rely on the return value of the ixgbe_fc_enable call now since there should be no cases where it returns an error that would normally be ignored.

This patch allows us to avoid a Tx hang when SR-IOV is enabled. This hang can be triggered by sending small packets at a rate that was triggering Rx missed errors from the adapter while the internal Tx switch and at least one VF are enabled. This was all due to the fact that under heavy stress the Rx FIFO never drained below the flow control high water mark. This resulted in the Tx FIFO being head of line blocked due to the fact that it relies on the flow control high water mark to determine when it is acceptable for the Tx to place a packet in the Rx FIFO. The resolution for this is to set the FCRTH value to the RXPBSIZE - 32 so that even if the ring is almost completely full we can still place Tx packets on the Rx ring and drop incoming Rx traffic if we do not have sufficient space available in the Rx FIFO.

A previous fix had gone though and disabled relaxed ordering for Rx descriptor read fetching. This was not necessary as this functions correctly and has no ill effects on the system. In addition several of the defines used for the DCA control registers were incorrect in that they indicated descriptor effects when they actually had an impact on either data or header write back. As such I have update these to correctly reflect either DATA or HEAD.

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.

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: NJesse Brandeburg <jesse.brandeburg@intel.com> Tested-by: NAaron Brown <aaron.f.brown@intel.com> Signed-off-by: NJeff Kirsher <jeffrey.t.kirsher@intel.com>
