Subject: [PATCH v3 02/10] net: eth: altera: set rx and tx ring size before init_dma call
Date: Thu, 4 Jun 2020 15:32:48 +0800 [thread overview]
Message-ID: <20200604073256.25702-3-joyce.ooi@intel.com> (raw)
In-Reply-To: <20200604073256.25702-1-joyce.ooi@intel.com>
From: Dalon Westergreen <dalon.westergreen@intel.com>
It is more appropriate to set the rx and tx ring size before calling
the init function for the dma.
