Subject: net: hns3: add int_gl_idx setup for VF
Patch-mainline: v4.16-rc1
Git-commit: 79eee41085414c25c788cd98b78e8776551d837f
References: bsc#1104353 FATE#326415
Just like PF, if the int_gl_idx of VF does not be set, the default
interrupt coalesce index of VF is 0. But it should be GL1 for TX
queues and GL0 for RX queues.
This patch adds the int_gl_idx setup for VF.
Fixes: 200ecda42598 ("net: hns3: Add HNS3 VF HCL(Hardware Compatibility Layer) Support")
