Revision c62041c5baa9ded3bc6fd38d3f724de70683b489 authored by Erik Ekman on 19 October 2021, 21:13:32 UTC, committed by David S. Miller on 21 October 2021, 11:38:34 UTC
The 1/10GbaseT modes were set up for cards with SFP+ cages in 3497ed8c852a5 ("sfc: report supported link speeds on SFP connections"). 10GbaseT was likely used since no 10G fibre mode existed. The missing fibre modes for 1/10G were added to ethtool.h in 5711a9822144 ("net: ethtool: add support for 1000BaseX and missing 10G link modes") shortly thereafter. The user guide available at https://support-nic.xilinx.com/wp/drivers lists support for the following cable and transceiver types in section 2.9: - QSFP28 100G Direct Attach Cables - QSFP28 100G SR Optical Transceivers (with SR4 modules listed) - SFP28 25G Direct Attach Cables - SFP28 25G SR Optical Transceivers - QSFP+ 40G Direct Attach Cables - QSFP+ 40G Active Optical Cables - QSFP+ 40G SR4 Optical Transceivers - QSFP+ to SFP+ Breakout Direct Attach Cables - QSFP+ to SFP+ Breakout Active Optical Cables - SFP+ 10G Direct Attach Cables - SFP+ 10G SR Optical Transceivers - SFP+ 10G LR Optical Transceivers - SFP 1000BASE‐T Transceivers - 1G Optical Transceivers (From user guide issue 28. Issue 16 which also includes older cards like SFN5xxx/SFN6xxx has matching lists for 1/10/40G transceiver types.) Regarding SFP+ 10GBASE‐T transceivers the latest guide says: "Solarflare adapters do not support 10GBASE‐T transceiver modules." Tested using SFN5122F-R7 (with 2 SFP+ ports). Supported link modes do not change depending on module used (tested with 1000BASE-T, 1000BASE-BX10, 10GBASE-LR).
