From 4c670dfaa417bc5604c9c58b505a74e2725acdb2 Mon Sep 17 00:00:00 2001 From: Guoyang Zhou Date: Tue, 23 Mar 2021 21:17:51 +0800 Subject: [PATCH] net/hinic: fix crash in secondary process Some apps, such as fstack, will use secondary process to access the memory of eth_dev_ops, and they want to get the info of dev, but hinic driver does not initialized it when in secondary process.
