Subject: [PATCH 20/35] net/ionic: overhaul transmit side for performance
Date: Fri, 7 Oct 2022 10:43:21 -0700	[thread overview]
Message-ID: <20221007174336.54354-21-andrew.boyer@amd.com> (raw)
In-Reply-To: <20221007174336.54354-1-andrew.boyer@amd.com>

Linearize Tx mbuf chains in the info array.
This avoids walking the mbuf chain during flush.
Move a few branches out of the hot path.
