Subject: [PATCH net-next 2/2] net: stmmac: remove duplicate dma queue channel macros
Date: Fri, 21 Oct 2022 19:47:11 +0800 [thread overview]
Message-ID: <20221021114711.1610797-2-junxiao.chang@intel.com> (raw)
In-Reply-To: <20221021114711.1610797-1-junxiao.chang@intel.com>
It doesn't need extra macros for queue 0 & 4. Same macro could
be used for all 8 queues.
