Intel Wired LAN Driver Updates 2023-01-03 (igc)
Muhammad Husaini Zulkifli says:
Improvements to the Time-Sensitive Networking (TSN) Qbv Scheduling
capabilities were included in this patch series for I226 SKU.
An overview of each patch series is given below:
Patch 1: To enable basetime scheduling in the future, remove the existing
restriction for i226 stepping while maintain the restriction for i225.
Patch 2: Remove the restriction which require a controller reset when
setting the basetime register for new i226 steps and enable the second
GCL configuration.
Patch 3: Remove the power reset adapter during disabling the tsn config.
