From: Kalesh AP Date: Thu, 24 Oct 2019 07:44:23 +0000 (+0530) Subject: net/bnxt: fix race between start and interrupt handler X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=a73b8e939f10;p=dpdk.git net/bnxt: fix race between start and interrupt handler During port start, driver enables interrupts. At the end of port start driver schedules the alarm for fw health check. This can cause race between interrupt handler and schedule fw health check alarm thread which falsely detects FW error.
