From 68e5cfaffaca73bda1263c503f9b186a196dd97b Mon Sep 17 00:00:00 2001 From: Joao Pinto Date: Mon, 13 Mar 2017 10:36:29 +0000 Subject: [PATCH] net: stmmac: added default rx queue size in stmmac_dma_interrupt This patch adds the rx queue default size when dma interrupts are treated, since dma op mode can be also set there.
