Muhammad Husaini Zulkifli says:

This patch series improves the Time-Sensitive Networking(TSN) Qbv Scheduling
features. I225 stepping had some hardware restrictions; I226 enables us to
further enhance the driver code and offer more Qbv capabilities.

An overview of each patch is given below:

Patch 1: Allow configuring the basetime with a value of zero.
Patch 2: To enable basetime scheduling in the future, remove the existing
restriction for i226 stepping while maintain the restriction for i225.
Patch 3: Ensure basetime values are not negative
Patch 4: Handle the Qbv end time correctly if cycle time parameter is
configured during the Gate Control List. Applicable for both i225 and i226.
Patch 5: Remove the restriction which require a controller reset when
setting the basetime register for new i226 steps and enable the second
GCL configuration.
Patch 6: Setting the Qbv start time and end time properly if the particular
gate is close in the Gate Control List due to hardware bug.
Patch 7: Configure strict cycle for better behaved transmissions
Patch 8: Allow scheduling packet to next cycle for i225

Test Procedure:
Talker: udp_tai application is being used to generate the Qbv packet.
Receiver: Capture using tcpdump to analyze the packet using wireshark.

The following are changes since commit 343a5d358e4ab5597e90e1eafa7eba55eb42e96b:
  net: phy: mxl-gpy: rename MMD_VEND1 macros to match datasheet
and are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue 1GbE
