Subject: [PATCH 3/6] net/txgbe: add RSS register selection for Amber-Lite 25G VF
Date: Thu, 23 Oct 2025 20:13:52 +0800 [thread overview]
Message-ID: <20251023121356.21944-4-zaiyuwang@trustnetic.com> (raw)
In-Reply-To: <20251023121356.21944-1-zaiyuwang@trustnetic.com>
A mapping function is used to distinguish between PF and VF during RSS
setup, ensuring access to the correct registers. This feature is added
specifically for Amber-Lite 25G VF, while 40G VF remains unchanged.
