Subject: [PATCH v2 08/10] qla2xxx: Reduce exess wait during chip reset
Date: Wed, 21 Dec 2016 13:57:37 -0800	[thread overview]
Message-ID: <1482357459-31079-9-git-send-email-himanshu.madhani@cavium.com> (raw)
In-Reply-To: <1482357459-31079-1-git-send-email-himanshu.madhani@cavium.com>

From: Quinn Tran <quinn.tran@cavium.com>

Soft reset and Risc reset should take 100uS to complete.
This change pad the timeout up to 400uS, which should be
plenty.
