linux 4.9: i40e NIC stops receiving unicast packages
Last modified: 2021-07-05 10:21:55 CEST
If an i40e NIC receives certain types of short(?) packages the NIC stops receiving all unicast packages: they no longer arrive on the bridge and the VMs connected to it. The problem was git-bisected to to <https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f114dca2533ca770aebebffb5ed56e5e7d1fb3fb> from v4.10-rc1 missing in v4.9.273 git bisect start '--' 'drivers/net/ethernet/intel/i40e' # new: [c470abd4fde40ea6a0846a2beab642a578c0b8cd] Linux 4.10 git bisect new c470abd4fde40ea6a0846a2beab642a578c0b8cd # old: [69973b830859bc6529a7a0468ba0d80ee5117826] Linux 4.9 git bisect old 69973b830859bc6529a7a0468ba0d80ee5117826 # old: [13fd3f9cc3def8b276c7913ae4acbfa2653cb198] i40e: clear mac filter count on reset git bisect old 13fd3f9cc3def8b276c7913ae4acbfa2653cb198 # new: [7ec9ba11b046b4b7fd768c366870ada60d409295] i40e: Driver prints log message on link speed change git bisect new 7ec9ba11b046b4b7fd768c366870ada60d409295 # new: [0b7c8b5d5436317a5f4509e2a150c6cec017f348] i40e: fix trivial typo in naming of i40e_sync_filters_subtask git bisect new 0b7c8b5d5436317a5f4509e2a150c6cec017f348 # new: [f114dca2533ca770aebebffb5ed56e5e7d1fb3fb] i40e: Be much more verbose about what we can and cannot offload git bisect new f114dca2533ca770aebebffb5ed56e5e7d1fb3fb # old: [81fa7c97bebd6e1a52c4e059eeffe18df5b3f11f] i40e: Implementation of ERROR state for NVM update state machine git bisect old 81fa7c97bebd6e1a52c4e059eeffe18df5b3f11f # old: [3aa7b74dbeedfb32406fec70cfd76d797209e8c9] i40e: removed unreachable code git bisect old 3aa7b74dbeedfb32406fec70cfd76d797209e8c9 # first new commit: [f114dca2533ca770aebebffb5ed56e5e7d1fb3fb] i40e: Be much more verbose about what we can and cannot offload
