Subject: [PATCH net] ice: Fix package download algorithm
Date: Wed, 8 May 2024 10:19:07 -0700 [thread overview]
Message-ID: <20240508171908.2760776-1-anthony.l.nguyen@intel.com> (raw)
From: Dan Nowlin <dan.nowlin@intel.com>
Previously, the driver assumed that all signature segments would contain
one or more buffers to download. In the future, there will be signature
segments that will contain no buffers to download.
Correct download flow to allow for signature segments that have zero
download buffers and skip the download in this case.
Fixes: 3cbdb0343022 ("ice: Add support for E830 DDP package segment")
