Subject: [PATCH 07/10] net/iavf: permit secondary process Tx path selection
Date: Thu,  5 Feb 2026 10:30:05 +0000	[thread overview]
Message-ID: <20260205103008.190493-8-ciara.loftus@intel.com> (raw)
In-Reply-To: <20260205103008.190493-1-ciara.loftus@intel.com>

Commit ebcfb039afa8 ("net/iavf: use common Tx path selection
infrastructure") changed the way that secondary processes selected their
Tx burst function. Instead of letting secondary processes select their
own function, they now used the function selected by the primary
process. However, the primary process only selects the function at
device start, so if the primary process hadn't started the device by the
time the secondary process was selecting its Tx burst function, the
secondary process would not select the correct function.

This commit addresses this issue by allowing the secondary process to
select the path if the device has not been started yet.

Fixes: ebcfb039afa8 ("net/iavf: use common Tx path selection infrastructure")
