From 3be4c6f38ea1e2fd66f21872f38a2fb42d0fd36c 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 [ upstream commit 4c670dfaa417bc5604c9c58b505a74e2725acdb2 ] 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.
