From cfe16d5da88896fc78d008c96d639cf9c90850a0 Mon Sep 17 00:00:00 2001 From: Hiral Patel Date: Tue, 12 Feb 2013 17:00:59 -0800 Subject: [PATCH] [SCSI] fnic: Fix SGEs limit 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.
