From 698a89541c223b247a3b08cd0b16c97344445d96 Mon Sep 17 00:00:00 2001 From: Yunsheng Lin Date: Sat, 4 Jan 2020 10:49:24 +0800 Subject: [PATCH 1/8] net: hns3: add trace event support for HNS3 driver This adds trace support for HNS3 driver. It also declares some events which could be used to trace the events when a TX/RX BD is processed, and other events which are related to the processing of sk_buff, such as TSO, GRO.

This patch modifies the misc IRQ names as "hclge/hclgevf"-misc- "pci name". And now the IRQ name is not related to net device name anymore, so change the HNAE3_INT_NAME_LEN to 32 bytes, and that is enough.
