[ Upstream commit cca28ceac7c7857bc2d313777017585aef00bcc4 ]
Remove unnecessary delay during the TX ring configuration. This will cause delay, especially during link down and link up activity.
Furthermore, old SKUs like as I225 will call the reset_adapter to reset the controller during TSN mode Gate Control List (GCL) setting. This will add more time to the configuration of the real-time use case.
It doesn't mentioned about this delay in the Software User Manual. It might have been ported from legacy code I210 in the past.
