Subject: [PATCH v3 2/6] examples/l3fwd: remove redundant Tx queue limit
Date: Thu, 25 Jun 2026 10:46:52 -0700 [thread overview]
Message-ID: <20260625174908.278408-3-stephen@networkplumber.org> (raw)
In-Reply-To: <20260625174908.278408-1-stephen@networkplumber.org>
From: Sivaprasad Tummala <sivaprasad.tummala@amd.com>
In `l3fwd` application, Tx queues are configured per lcore
to enable a lockless design and achieve optimal performance.
The `MAX_TX_QUEUE_PER_PORT` macro, defined as `RTE_MAX_LCORE`
which is dead code.
