Subject: [dpdk-dev] [PATCH 09/53] net/sfc/base: check NVRAM locking by partition ID
Date: Thu, 16 Nov 2017 08:03:57 +0000	[thread overview]
Message-ID: <1510819481-6809-10-git-send-email-arybchenko@solarflare.com> (raw)
In-Reply-To: <1510819481-6809-1-git-send-email-arybchenko@solarflare.com>

From: Andy Moreton <amoreton@solarflare.com>

Tracking which partition is locked avoids being overly conservative
when EFX_NVRAM_xxx maps to more than one partition (depnding on the
current port number).
