2011-03-03ixgbe: add function pointer for semaphore functionDon Skidmore
The X540 devices grabs semaphores differently than 82599 and 82598 devices do. They do however also grab them in allot of the same functions. So I'm adding a new MAC operation function pointer to allow us to use the correct function based on our MAC type. I'm also changing all the semaphore calls to use this new function pointer.

Double resets are required for recovery from certain error conditions. Between resets, it is necessary to stall to allow time for any pending HW events to complete. We use 1usec since that is what is needed for ixgbe_disable_pcie_master(). The second reset then clears out any effects of those events.

2011-01-10ixgbe: update ntuple filter configurationAlexander Duyck
This change fixes several issues found in ntuple filtering while I was doing the ATR refactor. Specifically I updated the masks to work correctly with the latest version of ethtool, I cleaned up the exception handling and added detailed error output when a filter is rejected, and corrected several bits that were set incorrectly in ixgbe_type.h. The previous version of this patch included a printk that was left over from me fixing the filter setup. This patch does not include that printk.

2011-01-10ixgbe: further flow director performance optimizationsAlexander Duyck
This change adds a compressed input type for atr signature hash computation. It also drops the use of the set functions when setting up the ATR input since we can then directly setup the hash input as two dwords that can be stored and passed as registers. With these changes the cost of computing the has is low enough that we can perform a hash computation on each TCP SYN flagged packet allowing us to drop the number of flow director misses considerably in tests such as netperf TCP_CRR.

2010-11-17ixgbe: DCB set PFC high and low water marks per data sheet specsJohn Fastabend
Currently the high and low water marks for PFC are being set conservatively for jumbo frames. This means the RX buffers are being underutilized in the default 1500 MTU. This patch fixes this so that the water marks are set as described in the data sheet considering the MTU size. The equation used is, RTT * 1.44 + MTU * 1.44 + MTU Where RTT is the round trip time and MTU is the max frame size in KB. To avoid floating point arithmetic FC_HIGH_WATER is defined ((((RTT + MTU) * 144) + 99) / 100) + MTU This changes how the hardware field fc.low_water and fc.high_water are used. With this change they are no longer storing the actual low water and high water markers but are storing the required head room in the buffer. This simplifies the logic and we do not need to account for the size of the buffer when setting the thresholds. Testing with iperf and 16 threads showed a slight uptick in throughput over a single traffic class .1-.2Gbps and a reduction in pause frames. Without the patch a 30 second run would show ~10-15 pause frames being transmitted with the patch ~2-5 are seen. Test were run back to back with 82599. Note RXPBSIZE is in KB and low and high water marks fields are also in KB. However the FCRT* registers are 32B granularity and right shifted 5 into the register, (((rx_pbsize - water_mark) * 1024) / 32) << 5 is the most explicit conversion here we simplify (rx_pbsize - water_mark) * 32 << 5 = (rx_pbsize - water_mark) << 10 This patch updates the PFC thresholds and legacy FC thresholds.

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.
