Subject: [PATCH V1 9/9] bnxt_en: Pass NQ ID to the FW when allocating RX/RX AGG rings
Date: Thu, 9 May 2024 11:27:41 -0500 [thread overview]
Message-ID: <20240509162741.1937586-10-wei.huang2@amd.com> (raw)
In-Reply-To: <20240509162741.1937586-1-wei.huang2@amd.com>
From: Michael Chan <michael.chan@broadcom.com>
Newer firmware can use the NQ ring ID associated with each RX/RX AGG
ring to enable PCIe steering tag. Older firmware will just ignore the
information.
