Subject: [PATCH v6 02/10] net: eth: altera: set rx and tx ring size before init_dma call
Date: Tue, 18 Aug 2020 23:46:05 +0800	[thread overview]
Message-ID: <20200818154613.148921-3-joyce.ooi@intel.com> (raw)
In-Reply-To: <20200818154613.148921-1-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.
