2012-02-07Revert "skge: check for PCI dma mapping errors"stephen hemminger
As reported by several people... The code in rx_clean was panic'ing so revert commit d0249e44432aa0ffcf710b64449b8eaa3722547e. Will redo DMA mapping checks as new patches for a later release.

2012-02-07e1000e: cleanup - check return values consistentlyBruce Allan
The majority of the e1000e code checks most function return values using a test like 'if (ret_val)' or 'if (!ret_val)' but there are a few instances of 'if (ret_val == 0)'.

2012-02-07igbvf: refactor Interrupt Throttle Rate codeMitch A Williams
The existing ITR code is broken and confusing, with lots of similarly-named variables that do different things. Additionally, after the driver carefully determines the optimal interrupt rate for the adapter, it then ignores it and always writes a fixed, suboptimal value. This patch refactors that code to make variable names more descriptive of what they actually do, and then actually writes the calculated result to the hardware. Preliminary testing shows that netperf TCP_STREAM tests goes from ~918Mbps to ~940Mbps, and TCP_RR goes from ~2k transactions/sec up to > 8k.

2012-02-06mlx4: fix DMA mapping leak when allocation failsThadeu Lima de Souza Cascardo
mlx4_en_prepare_rx_desc does not correctly clean up after it finds an allocation failure. It should unmap a page before calling put_page, but it only calls the later. This bug would prevent a device removal using hotplug after setting the device MTU to 9000 and opening the network interface. After the fix, we still see the allocation failure with MTU 9000, but we are able to remove the device.

2012-02-06mlx4: allow device removal by fixing dma unmap sizeThadeu Lima de Souza Cascardo
After opening the network interface, Mellanox ConnectX device cannot be removed by hotplug because it has not properly unmapped all DMA memory. It happens that mlx4_en_activate_rx_rings overrides the variable that keeps the size of the memory mapped. This is fixed by passing to mlx4_en_destroy_rx_ring the same size that is given to mlx4_en_create_rx_ring. After applying this patch, hot unplugging the device works after opening the interface.

2012-02-06ath9k_hw: fix a RTS/CTS timeout regressionFelix Fietkau
commit adb5066 "ath9k_hw: do not apply the 2.4 ghz ack timeout workaround to cts" reduced the hardware CTS timeout to the normal values specified by the standard, but it turns out while it doesn't need the same extra time that it needs for the ACK timeout, it does need more than the value specified in the standard, but only for 2.4 GHz. This patch brings the CTS timeout value in sync with the initialization values, while still allowing adjustment for bigger distances.

2012-02-06ath9k: fix a WEP crypto related regressionFelix Fietkau
commit b4a82a0 "ath9k_hw: fix interpretation of the rx KeyMiss flag" fixed the interpretation of the KeyMiss flag for keycache based lookups, however WEP encryption uses a static index, so KeyMiss is always asserted for it, even though frames are decrypted properly. Fix this by clearing the ATH9K_RXERR_KEYMISS flag if no keycache based lookup was performed.
