From: Birger Koblitz Date: Fri, 31 Dec 2021 16:53:40 +0000 (+0100) Subject: realtek: Increase zone size for Ethernet driver DMA X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b3287a21650bf1883f12efebdd7e0315ad750a59;p=openwrt%2Fstaging%2Fblogic.git realtek: Increase zone size for Ethernet driver DMA Set CONFIG_FORCE_MAX_ZONEORDER setting to 13 to allow larger contiguous memory allocation for the DMA of the Ethernet driver. Increase the number of entries in the RX ring to 300 making use of the larger DMA region now possible for receiveing packets.
