From b0d6cabd355ae9c13c53680cfe8b5ae58a84d2c1 Mon Sep 17 00:00:00 2001 From: Himanshu Madhani Date: Thu, 17 Dec 2015 14:56:56 -0500 Subject: [PATCH] qla2xxx: Enable Extended Logins support This patch enables Extended Logins support in Qlogic ISP. To enable extended login with Qlogic ISP24XX/25XX/26XX, set module parameter ql2xexlogins to any non-zero number. This will alow ISP firmware to store port database structure information of remote login sessions to host memory provided by driver. ISP firmware supports upto 16k total logins.
