Commit "ath9k_hw: Abort rx if hw is not coming out of full sleep in reset" uncondionally added aborting RX DMA in a HW reset, though it is a bit unclear as to why this is needed. Anyway, RX DMA is handled in the target for USB devices, and this would interfere with normal operations (scanning etc.), so fix this. Signed-off-by:

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. Signed-off-by:

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.

This change cleans up the layout of the flow director data, and the algorithm used to calculate the hash resulting in a 35x / 3500% performance increase versus the old flow director hash computation. The overall effect is only a 1% increase in transactions per second though due to the fact that only 1 packet in 20 are actually hashed upon. TCP_RR before: Socket Size Request Resp. Elapsed Trans.

When disable the Rx logic globally, we would also want to disable the per Rx queue receive logic by per queue Rx control register RXDCTL so no more DMA is happening from the packet buffer to the receive buffer associated with the Rx ring, before we start unmapping Rx ring receive buffer. The hardware may take max of 100us before the corresponding Rx queue is really disabled. Added ixgbe_disable_rx_queue() for this purpose. Signed-off-by:

Some Phys supported by the driver do not remain powered off across a reset of the device when the interface is down, e.g. on 82571, but not on 82574. This patch powers down (only when WoL is disabled) the PHY after a reset if the interface is down and the ethtool diagnostics are not currently running. The ethtool diagnostic function required a minor re-factor as a result, and the e1000_[get|put]_hw_control() functions are renamed since they are no longer static to netdev.c as they are needed by the ethtool diagnostics. A couple minor whitespace issues were cleaned up, too. Reported-by:

The ICR register is clear on read and we don't care what the returned value is when resetting the hardware so the icr variable(s) can be removed. We should not ignore the return from e1000_lv_jumbo_workaround_ich8lan() and from e1000_get_phy_id_82571() (dump a debug message when it fails and when an unknown Phy id is returned). Signed-off-by:

In order to compute the features for other offloads (primarily scatter/gather), we need to first check the ability of the NIC to offload the checksum for the packet. Since we have already computed this, we can directly use the result instead of figuring it out again. Signed-off-by:

This switches skb_need_linearize() to use the features that have been centrally computed. In doing so, this fixes a problem where scatter/gather should not be used because the card does not support checksum offloading on that type of packet. On device registration we only check that some form of checksum offloading is available if scatter/gatther is enabled but we must also check at transmission time. Examples of this include IPv6 or vlan packets on a NIC that only supports IPv4 offloading. Signed-off-by:

Now that there is a single function that can compute the device features relevant to a packet, we don't want to run it for each offload. This converts netif_needs_gso() to take the features of the device, rather than computing them itself. Signed-off-by:

Jesse Gross authored
netif_get_vlan_features() is currently only used by netif_needs_gso(), so it only concerns itself with GSO features. However, several other places also should take into account the contents of the packet when deciding whether to offload to hardware. This generalizes the function to return features about all of the various forms of offloading. Since offloads tend to be linked together, this avoids duplicating the logic in each location (i.e. the scatter/gather code also needs the checksum logic). Suggested-by:

Jesse Gross authored
We currently only have software fallback for one type of checksum: the TCP/UDP one's complement. This means that a protocol that uses hardware offloading for a different type of checksum (FCoE, SCTP) must directly check the device's features and do the right thing ahead of time. By the time we get to dev_can_checksum(), we're only deciding whether to apply the one algorithm in software or hardware. NETIF_F_HW_CSUM has the same capabilities as the software version, so we should always use it if present. The primary advantage of this is multiply tagged vlans can use hardware checksumming.

Due to NLM_F_DUMP is composed of two bits, NLM_F_ROOT | NLM_F_MATCH, when doing "if (x & NLM_F_DUMP)", it tests for _either_ of the bits being set. Because NLM_F_MATCH's value overlaps with NLM_F_EXCL, non-dump requests with NLM_F_EXCL set are mistaken as dump requests. Substitute the condition to test for _all_ bits being set. Signed-off-by:

The forcedeth driver uses the legacy PCI power management, so it has to do PCI-specific things in its ->suspend() and ->resume() callbacks and some of them are not done correctly. Convert forcedeth to the new PCI power management framework and make it let the PCI subsystem take care of all the PCI-specific aspects of device handling during system power transitions.

Madge Ambassador ATM Adapter driver: Always release_firmware() in ucode_init() and don't leak memory. Failure to call release_firmware() will result in memory leak in drivers/atm/ambassador.c::ucode_init(). This patch makes sure we always call release_firmware() when needed, thus removing the leak(s). Yes, I know checkpatch complains about this patch, but it was either that or completely mess up the existing style, so I opted to use the existing style and live with the checkpatch related flak.
