  "message": "iavf: fix netdev-\u003emax_mtu to respect actual hardware limit\n\n[ Upstream commit b84852170153671bb0fa6737a6e48370addd8e1a ]\n\niavf sets LIBIE_MAX_MTU as netdev-\u003emax_mtu, ignoring vf_res-\u003emax_mtu\nfrom PF [1]. This allows setting an MTU beyond the actual hardware\nlimit, causing TX queue timeouts [2].\n\nSet correct netdev-\u003emax_mtu using vf_res-\u003emax_mtu from the PF.\n\nNote that currently PF drivers such as ice/i40e set the frame size in\nvf_res-\u003emax_mtu, not MTU. Convert vf_res-\u003emax_mtu to MTU before setting\nnetdev-\u003emax_mtu.\n\n[1]\n # ip -j -d link show $DEV | jq \u0027.[0].max_mtu\u0027\n 16356\n\n[2]\n iavf 0000:00:05.0 enp0s5: NETDEV WATCHDOG: CPU: 1: transmit queue 0 timed out 5692 ms\n iavf 0000:00:05.0 enp0s5: NIC Link is Up Speed is 10 Gbps Full Duplex\n iavf 0000:00:05.0 enp0s5: NETDEV WATCHDOG: CPU: 6: transmit queue 3 timed out 5312 ms\n iavf 0000:00:05.0 enp0s5: NIC Link is Up Speed is 10 Gbps Full Duplex\n ...\n\nFixes: 5fa4caff59f2 (\"iavf: switch to Page Pool\")\nSigned-off-by: Kohei Enju \u003ckohei@enjuk.jp\u003e\nReviewed-by: Alexander Lobakin \u003caleksander.lobakin@intel.com\u003e\nReviewed-by: Simon Horman \u003chorms@kernel.org\u003e\nTested-by: Rafal Romanowski \u003crafal.romanowski@intel.com\u003e\nSigned-off-by: Tony Nguyen \u003canthony.l.nguyen@intel.com\u003e\nSigned-off-by: Sasha Levin \u003csashal@kernel.org\u003e\n",
