Subject: [PATCH v1 5/5] net/cpfl: fix RX data buffer size
Date: Fri, 14 Apr 2023 11:51:51 +0800 [thread overview]
Message-ID: <20230414035151.1377726-6-wenjun1.wu@intel.com> (raw)
In-Reply-To: <20230414035151.1377726-1-wenjun1.wu@intel.com>
This patch does two fixes.
1. No matter what the mbuf size is, the data buffer size should not
be greater than 16K - 128.
2. Align data buffer size to 128.
