From 5fd4789a98f8661a0e8db3daf21b774213c99487 Mon Sep 17 00:00:00 2001 From: Fuyun Liang Date: Fri, 12 Jan 2018 16:23:11 +0800 Subject: net: hns3: refactor interrupt coalescing init function In the hardware, the coalesce configurable registers include GL0, GL1, GL2. In the driver, the TX queues use the register GL1 and the RX queues use the register GL0. This function initializes the configuration of the interrupt coalescing, but does not distinguish between the TX direction and the RX direction. It will cause some confusion. This patch refactors the function to initialize the TX GL and the RX GL separately. And the initialization of related variables also is added to this patch.
