Public bug reported: [Impact] rx performance is sub-optimal with EVB-LAN7430 NICs.
[Test Case] Use iperf3 to submit TCP or UDP traffic to a host w/ a EVB-LAN7430 NIC. [Fix] Cherry-pick the following upstream commit: a1f1627540cde net: ethernet: microchip: lan743x: Increase rx ring size to improve rx performance [What could go wrong] The patch will slightly increase memory usage, which could possibly add memory pressure to memory-restricted systems. ** Affects: linux (Ubuntu) Importance: Undecided Status: Confirmed ** Affects: linux (Ubuntu Focal) Importance: Undecided Status: Confirmed ** Affects: linux (Ubuntu Hirsute) Importance: Undecided Status: Confirmed ** Affects: linux (Ubuntu Impish) Importance: Undecided Status: Confirmed ** Affects: linux (Ubuntu Jammy) Importance: Undecided Status: Confirmed ** Changed in: linux (Ubuntu) Status: New => Confirmed ** Also affects: linux (Ubuntu Impish) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Jammy) Importance: Undecided Status: Confirmed ** Also affects: linux (Ubuntu Hirsute) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Focal) Status: New => Confirmed ** Changed in: linux (Ubuntu Hirsute) Status: New => Confirmed ** Changed in: linux (Ubuntu Impish) Status: New => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1954833 Title: net: ethernet: microchip: lan743x: Increase rx ring size to improve rx performance Status in linux package in Ubuntu: Confirmed Status in linux source package in Focal: Confirmed Status in linux source package in Hirsute: Confirmed Status in linux source package in Impish: Confirmed Status in linux source package in Jammy: Confirmed Bug description: [Impact] rx performance is sub-optimal with EVB-LAN7430 NICs.
