Subject: [PATCH 02/70] net/ice/base: get NVM CSS Header length from the CSS Header
Date: Mon, 15 Aug 2022 03:11:58 -0400	[thread overview]
Message-ID: <20220815071306.2910599-3-qi.z.zhang@intel.com> (raw)
In-Reply-To: <20220815071306.2910599-1-qi.z.zhang@intel.com>

The CSS Header length is defined as ICE_CSS_HEADER_LENGTH. To
support changes in CSS Header length, calculate the CSS Header
length from the NVM CSS Header length field plus the Authentication
Header length.
