Subject: [PATCH v2 1/4] net/nbl: change default Rx extension header size to 12 bytes
Date: Tue, 11 Nov 2025 03:31:40 -0800 [thread overview]
Message-ID: <20251111113144.3567291-2-dimon.zhao@nebula-matrix.com> (raw)
In-Reply-To: <20251111113144.3567291-1-dimon.zhao@nebula-matrix.com>
The default Rx extension header size is reduced from 16 bytes to 12 bytes.
This reduction saves PCIe bandwidth by decreasing packet overhead.
