Subject: [PATCH V2 net-next 09/11] net: hns3: add int_gl_idx setup for TX and RX queues

From: Fuyun Liang <liangfuyun1@...wei.com>

If the int_gl_idx does not be set, the default interrupt coalesce index
is 0. The TX queues and the RX queues will both use the GL0 as the
interrupt coalesce GL switch. But it should be GL1 for TX queues and GL0
for RX queues.

This patch adds the int_gl_idx setup for TX queues and RX queues.

Fixes: 76ad4f0ee747 ("net: hns3: Add support of HNS3 Ethernet Driver for hip08 SoC")
