Subject: [dpdk-dev] [PATCH] common/octeontx2: reduce wait time for mbox messages
Date: Mon, 16 Dec 2019 20:32:53 +0530 [thread overview]
Message-ID: <20191216150253.22835-1-skori@marvell.com> (raw)
After each mbox send operation, context waits for minimum 1ms to get
corresponding response although response can come earlier.
So reducing wait time to lower granularity.
