Subject: [PATCH net-next 3/3] include/stmmac: Increase max DMA/MTL channel count from 8 to 16
Date: Mon, 11 May 2026 18:54:16 +0200 [thread overview]
Message-ID: <20260511165416.3093015-4-j.raczynski@samsung.com> (raw)
In-Reply-To: <20260511165416.3093015-1-j.raczynski@samsung.com>
Newer XGMAC hardware does support up to 16 DMA/MTL queues.
Add support for these after previous modifications of driver to accomodate for
that.
