These values\nare not configurable in this implementation.\n\nIn general, the DPDK driver expects the RSS hash configuration to be set\nwith a key before the redriection table is set up. When the RSS hash is\nconfigured, a default redirection table is generated based on the number\nof queues. When the device is re-configured, the redirection table is\nreset to the default value based on the queue count.\n\nAn important note is that the gVNIC device expects 32 bit integers for\nRSS redirection table entries, while the RTE API uses 16 bit integers.\nHowever, this is unlikely to be an issue, as these values represent\nreceive queues, and the gVNIC device does not support anywhere near 64K\nqueues.\n\nThis series also updates the corresponding feature matrix ertries and\ndocumentation as it pertains to RSS support in the GVE driver.\n\nv2:\nAdd commmit messages for patches with it missing, and other checkpatches\nfixes.\n\nNote: There is a warning about complex macros being parenthesized that\ndoes not seem to be well-founded.\n\nv3:\nFix build warnings that come up on certain distros.\n\nJoshua Washington (7):\n net/gve: fully expose RSS offload support in dev_info\n net/gve: RSS adminq command changes\n net/gve: add gve_rss library for handling RSS-related behaviors\n net/gve: RSS configuration update support\n net/gve: RSS redirection table update support\n net/gve: update gve.ini with RSS capabilities\n net/gve: update GVE documentation with RSS support\n\n doc/guides/nics/features/gve.ini | 3 +\n doc/guides/nics/gve.rst | 16 ++-\n drivers/net/gve/base/gve.h | 15 ++\n drivers/net/gve/base/gve_adminq.c | 59 ++++++++\n drivers/net/gve/base/gve_adminq.h | 21 +++\n drivers/net/gve/gve_ethdev.c | 231 +++++++++++++++++++++++++++++-\n drivers/net/gve/gve_ethdev.h | 17 +++\n drivers/net/gve/gve_rss.c | 206 ++++++++++++++++++++++++++\n drivers/net/gve/gve_rss.h | 107 ++++++++++++++\n drivers/net/gve/meson.build | 1 +\n 10 files changed, 667 insertions(+), 9 deletions(-)\n create mode 100644 drivers/net/gve/gve_rss.c\n create mode 100644 drivers/net/gve/gve_rss.h" }
