Subject: [PATCH v1 6/9] baseband/acc: fix iteration counter in TB mode
Date: Thu,  9 Feb 2023 22:19:26 +0000	[thread overview]
Message-ID: <20230209221929.265059-7-nicolas.chautru@intel.com> (raw)
In-Reply-To: <20230209221929.265059-1-nicolas.chautru@intel.com>

The iteration count was not using correct structure (4G vs 5G)
in TB mode.

Fixes: bec597b78a0 ("baseband/acc200: add LTE processing")
Cc: stable@dpdk.org
