BugLink: http://bugs.launchpad.net/bugs/1547674 This is the "Don't Give Up" patch. Previously the driver could fail an allocation, and then possibly stall a queue forever, by never coming back to continue receiving or allocating buffers. With this patch, the driver will keep polling trying to allocate receive buffers until it succeeds. This should keep all receive queues running even in the face of memory pressure. Also update copyright year in file header. Change-ID: I2b103d1ce95b9831288a7222c3343ffa1988b81b Signed-off-by:

BugLink: http://bugs.launchpad.net/bugs/1547674 While re-enabling interrupts the driver would clear all pending causes. This meant that if an interrupt was generated while the driver was cleaning or polling with interrupts disabled, then that interrupt was lost. This could cause a queue to become dead, especially for receive. Refactored the enable_icr0 function in order to allow it to be decided by the caller whether the CLEARPBA (clear pending events) bit will be set while re-enabling the interrupt. Also update copyright year in file headers. Change-ID: Ic1db100a05e13c98919057696db147a258ca365a Signed-off-by:

BugLink: http://bugs.launchpad.net/bugs/1547674 Now that the Force-WriteBack functionality in X710/XL710 devices has been moved out of the clean routine and into the service task, we need to make sure WriteBack-On-ITR is separated out since it is still called from clean. In the X722 devices, Force-WriteBack implies WriteBack-On-ITR but without the interrupt, which put the driver into a missed interrupt scenario and a potential tx-timeout report. With this patch, we break the two functions out, and call the appropriate ones at the right place. This will avoid creating missed interrupt like scenarios for X722 devices. Also update copyright year in file headers. Change-ID: Iacbde39f95f332f82be8736864675052c3583a40 Signed-off-by:

Shannon Nelson authored
BugLink: http://bugs.launchpad.net/bugs/1547674 With the latest firmware, statistics gathering can now be enabled and disabled in the HW switch, so we need to add a parameter to allow the driver to set it as desired. At the same time, the L2 cloud filtering parameter has been removed as it was never used. Older drivers working with the newer firmware and newer drivers working with older firmware will not run into problems with these bits as the defaults are reasonable and there is no overlap in the bit definitions. Also, newer drivers will be forced to update because of the change in function call parameters, a reminder that the functionality exists. Also update copyright year.

BugLink: http://bugs.launchpad.net/bugs/1547674 Add the use of the new Shared MAC filter bit for multicast and broadcast filters in order to make better use of the filters available from the device. The FW folks have assured me that setting this bit on older FW will have no affect, so we don't need a version check. Also fixed a stray indent problem nearby. Also update copyright year.

BugLink: http://bugs.launchpad.net/bugs/1547674 Make the DCB firmware version related checks specific to X710 and XL710 only. These checks are not required for X722 family of devices. Introduced an inline routine to help determine if the MAC type is X710/XL710 or not. Moved the firmware version related checks in i40e_sw_init() and defined flags for different cases Fix the version check to allow using "Set LLDP MIB" AQ for beyond FVL4 FW releases.

BugLink: http://bugs.launchpad.net/bugs/1547674 The sync_vsi_filters function is moved up in the service_task because it may need to request a reset, and we don't want to wait another round of service task time. NOTE: Filters will be replayed by sync_vsi_filters including broadcast and promiscuous settings. Also, added some error handling in this space in case any of these fail the driver will retry correctly. Also update copyright year.

BugLink: http://bugs.launchpad.net/bugs/1547674 This adds an ixgbe data structure that is used to determine what headers:fields can be matched and in what order they are supported. For hardware devices this can be a bit tricky because typically only pre-programmed (firmware, ucode, rtl) parse graphs will be supported and we don't yet have an interface to change these from the OS. So its sort of a you get whatever your friendly vendor provides affair at the moment. In the future we can add the get routines and set routines to update this data structure. One interesting thing to note here is the data structure here identifies ethernet, ip, and tcp fields without having to hardcode them as enumerations or use other identifiers. Signed-off-by:
