[PATCH v4 19/20] net/txgbe: add RSS for Amber-Lite NICs

[Zaiyu Wang]

Add RSS (Receive Side Scaling) functionality for Amber-Lite NICs.
The Amber-Lite NIC series provides comprehensive RSS support with
hardware implementation identical to Sapphire NICs. This commit
enables RSS by applying the existing RSS configuration directly
to Amber-Lite NICs without requiring architectural changes.
