Patch V7: 1) Minor comments from v6 release regarding debug statements. 2) Fix for large multicast lists. 3) Fixed lockup issue if port initialization fails. 4) Enabled MSI by default. https://patchwork.ozlabs.org/patch/464441/ Patch V6: 1) Addressed the uint64 vs u64 issue, feedback from previous patch. 2) Consolidated some receive processing routines. 3) Removed link status polling method. https://patchwork.ozlabs.org/patch/459514/ Patch V5: Based on the feedback from earlier patches with regards to consolidation of common functions like device init, register programming for cn66xx and cn68xx devices. https://patchwork.ozlabs.org/patch/438979/ Patch V4: Following were the changes based on the feedback from earlier patch: 1) Added mmiowb while synchronizing queue updates and other hw interactions. 2) Statistics will now be incremented non-atomically per each ring. liquidio_get_stats will add stats of each ring while reporting the total statistics counts. 3) Modified liquidio_ioctl to return proper return codes. 4) Modified device naming to use standard Ethernet naming. 5) Global function names in the driver will have lio_/liquidio_/octeon_ prefix. 6) Ethtool related changes for: Removed redundant stats and jiffies. Use default ethtool handler of link status. Speed setting will make use of ethtool_cmd_speed_set. 7) Added checks for pci_map_* return codes. 8) Check for signals while waiting in interruptible mode https://patchwork.ozlabs.org/patch/435073/ Patch v3: Implemented feedback from previous patch like: Removed NAPI Config and DEBUG config options, added BQL and xmit_more support. https://patchwork.ozlabs.org/patch/422749/ Patch V2: Implemented feedback from previous patch. https://patchwork.ozlabs.org/patch/413539/ First Patch: https://patchwork.ozlabs.org/patch/412946/ Signed-off-by: Derek Chickles <derek.chickles@caviumnetworks.com> Signed-off-by: Satanand Burla <satananda.burla@caviumnetworks.com> Signed-off-by: Felix Manlunas <felix.manlunas@caviumnetworks.com> Signed-off-by: Robert Richter <Robert.Richter@caviumnetworks.com> Signed-off-by: Aleksey Makarov <Aleksey.Makarov@caviumnetworks.com> Signed-off-by: Raghu Vatsavayi <raghu.vatsavayi@caviumnetworks.com> Signed-off-by: David S.
