Subject: [PATCH 04/10] fnic: Fix SGEs limit
Date: Mon, 10 Dec 2012 01:21:32 -0800 [thread overview]
Message-ID: <1355131299-3313-4-git-send-email-hiralpat@cisco.com> (raw)
In-Reply-To: <1355131299-3313-1-git-send-email-hiralpat@cisco.com>
Driver allows IOs with more SGEs than max SGEs supported by Palo. The current max SGEs
supported by the fnic driver is 1024. The current register settings on Palo supports
a max of 256 only. Palo would return any IO with more than 256 SGEs with an error
indicating INVALID_SGLS. Fnic driver should limit the max supported SGLs in
the driver to 256 to avoid this error.
