2015-10-23ixgbe, ixgbevf: Add new mbox API xcast modeHiroshi Shimamoto
The limitation of the number of multicast address for VF is not enough for the large scale server with SR-IOV feature. IPv6 requires the multicast MAC address for each IP address to handle the Neighbor Solicitation message. We couldn't assign over 30 IPv6 addresses to a single VF. This patch introduces the new mailbox API, IXGBE_VF_UPDATE_XCAST_MODE, to update multicast mode of VF. This adds 3 modes; - NONE only L2 exact match addresses or Flow Director enabled - MULTI BAM and ROMPE set - ALLMULTI BAM, ROMPE and MPE set If a guest VF user wants over 30 MAC multicast addresses, set IFF_ALLMULTI to request PF to update xcast mode to enable VF multicast promiscuous mode. On the other hand, enabling VF multicast promiscuous mode may affect security and performance in the network of the NIC. Only trusted VF can enable multicast promiscuous mode. The behavior of untrusted VF is the same as previous version.

2015-07-23ixgbevf: add support for reporting RSS key and hash table for X550Emil Tantilov
This patch extends the reporting of the RSS key and hash table by adding support for X550 VFs. The difference is that X550 VFs have their own registers for RSS key and indirection table, so there is no need to query the PF. The RSS key and indirection table are stored in the adapter structure during the configuration of VFRSSRK and VFRETA which in turn can be used in ethtool for reporting. The logic for writing VFRETA is also changed to make sure that the indirection table is reported correctly. In addition this patch adds defines for the VFRETA entries and number of VFRSSRK registers as well as some whitespace cleanups.

2015-02-05ixgbevf: combine all of the tasks into a single service taskEmil Tantilov
This change combines the reset and watchdog tasklets into a single task. The advantage of this is that we can avoid multiple schedules of the reset task when we have a reset event needed due to either the mailbox going down or transmit packets being present on a link down.

2014-11-20ixgbevf: Change receive model to use double buffered page based receivesEmil Tantilov
This patch changes the basic receive path for ixgbevf so that instead of receiving the data into an skb it is received into a double buffered page. The main change is that the receives will be done in pages only and then pull the header out of the page and copy it into the sk_buff data. This has the advantages of reduced cache misses and improved performance on IOMMU enabled systems. v2: - added pfmemalloc check to a new function for reusable page - moved atomic_inc outside of #if/else in ixgbevf_add_rx_frag() - reverted the removal of the api check in ixgbevf_change_mtu() CC: Alexander Duyck <alexander.h.duyck@redhat.com> Signed-off-by: Emil Tantilov <emil.s.tantilov@intel.com> Tested-by: Phil Schmitt <phillip.j.schmitt@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2014-11-20ixgbevf: Update Rx next to clean in real timeEmil Tantilov
Since the next_to_clean value is only accessed by the Rx interrupt handler we can save on stack space by just storing our updated values back in next_to_clean instead of using the stack variable i. This should help to reduce stack space and we can further collapse the size of the function. Also removed non_eop_descs counter as it was never shown in the stats.

In addition instead of doing a byteswap on the status bits value, we can byteswap the constant values we are testing since that can be done at compile time which should help to improve performance on big-endian systems.

2014-04-11ixgbevf: Add bit to mark work queue initializationMark Rustad
An indication of work queue initialization is needed. This is because register accesses prior to that time can detect a removal and attempt to schedule the watchdog task. Adding the __IXGBEVF_WORK_INIT bit allows this to be checked and if not set prevent the watchdog task scheduling. By checking for a removal right after initialization, the probe can be failed at that point without getting the watchdog task involved.

In order to correct that we instead make next_to_watch a pointer that is set to NULL during cleanup, and set to the eop_desc after the descriptor rings have been written. To enforce proper ordering the next_to_watch pointer is not set until after a wmb writing the values to the last descriptor in a transmit. In order to guarantee that the descriptor is not read until after the eop_desc we use the read_barrier_depends which is only really necessary on the alpha architecture.
