Why I did it
The mst driver is redundant as most of the operations can be done without starting and stopping of this driver with the pci id instead, the mst driver start causes some driver issues in kernel code during config reload and DPU startup in smartswitch platforms, so it is removed.
Work item tracking
How I did it
remove mst restart in mlnx-fw-upgrade.sh file
Add it for DPU FPGA upgrade which increases degradation if we dont start mst
How to verify it
perform mst upgrade and check time for installation, and DPU_FPGA fwutil test.
Which release branch to backport (provide reason below if selected)
Tested branch (Please provide the tested image version)
