The error handling in the module init and exit functions can be shortened to safe us some code. 1/ Remove the code duplications in the init function, jump straight to the existing cleanup code by adding some labels. Also give the error message some more value by telling the reason why loading the module has failed. 2/ Remove the error handling in the exit function as the only legitimate reason xfrm6_protocol_deregister() might fail is inet6_del_protocol() returning -1. That, in turn, means some other protocol handler had been registered for this very protocol in the meantime. But that essentially means we haven't been handling that protocol any more, anyway. What it definitely means not is that we "can't deregister protocol". Therefore just get rid of that bogus warning. It's plain wrong.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-06-24 This series contains updates to i40e and i40evf. Greg provides a patch to stop the VF device after setting its MAC address. This is due to if the host VMM administrator has changed the VF device's MAC address then the i40e driver needs to halt the VF device so that the administrator will be forced to reload the VF driver so that the VF driver will start using the newly assigned MAC address. Shannon provides several patches for i40e, first makes prep_for_test() a void function since the return value was being ignored for the most part by all its callers. Adds a log warning when the firmware's API minor/major number is not what we expect to assist the user by informing them they may need to update their NVM or SW. Cleans up a stray print message so that it is similar to other print messages. Ensures to set the WoL flag when setting LAA and allow the user to set LAA again. So do not short-circuit the LAA assignment when the driver thinks it has already been done as it is possible that the user might want to force the address setting again. Provides a couple more LAA fixes to ensure the LAA gets restored after resets. Neerav provides a patch for i40e to add a PF reset when a malicious driver event for the PF occurs. As per the specification when the PF driver receives a malicious driver event the queue that caused the event is already stopped and it is expected that the function that owns the queue will reset the queue, but in some cases it may not be possible to determine the queue, so it is suggested to reset the whole function. Carolyn fixes ethtool coalesce settings to allow 0 as a disable value and adds message to user about invalid values. Jesse removes a reserved type which was not removed from the code. Catherine provides a patch to add the ability to enable/disable link from set_link)restart_an() which will make it easy to toggle link without calling set_phy_config() when no other link settings need to change. Anjali provides a patch to ensure we do a PF reset on Tx hang and that way we avoid any Malicious Driver Detect (MDD) events because of a Tx queue disable failure. v2: - fixed the un-needed return in patch 2 based on feedback from Sergei Shtylyov - added punctuation to print statements and code comment based on feedback from Sergei Shtylyov ==================== Signed-off-by: NDavid S.

There's no need for a full 32x32 matrix, when rows before the last are just shifted copies of the rows after them. There's still room for improvement (especially on X86 processors with CRC32 and PCLMUL instructions), but this is a large step in the right direction [which is in particular useful for its current user, namely SCTP checksumming over multiple skb frags[] entries, i.e. in IPVS balancing when other CRC32 offloads are not available]. The internal primitive is now called crc32_generic_shift and takes one less argument; the XOR with crc2 is done in inline wrappers.

由 Anjali Singhai Jain 提交于
When a Tx hang happens, usually the Tx queue disable fails. At this point if we try to recover by a VSI reinit the HW gets unhappy and we get a Malicious Driver Detect (MDD) event. HW expects a PF reset if a queue disable fails, if we don't do a PF reset and restart the queue we get an MDD. This patch makes sure we do a PF reset on Tx hang and that way we avoid any MDD because of Tx queue disable failure.

The return from i40e_prep_for_reset() was being ignored by almost all its callers. The one place it wasn't ignored could have caused a silent and confusing failure of the driver to finish a reset. Since we really are doing a rebuild anyway, ignore this last case as well and simply make the function a void type.

This patch adds supports for Accelerated Receive Flow Steering. When the desired rx is different from current rq, for a flow, kernel calls the driver function enic_rx_flow_steer(). enic_rx_flow_steer adds a IP-TCP/UDP hardware filter. Driver registers a timer function enic_flow_may_expire. This function is called every HZ/4 seconds. In this function we check if the added filter has expired by calling rps_may_expire_flow(). If the flow has expired, it removes the hw filter. As of now adaptor supports only IPv4 - TCP/UDP filters. Signed-off-by: NGovindarajulu Varadarajan <_govind@gmx.com> Signed-off-by: NDavid S.
