From b47acacd7c888ef550fb786dd02db69d9eb2faee Mon Sep 17 00:00:00 2001 From: Dhananjay Phadke Date: Thu, 1 Apr 2010 19:01:30 +0000 Subject: [PATCH] qlcnic: update oncard memory size check All QLogic converged NICs have 128-bit 128MB on card memory. Fix the limit check from 64MB to 128MB and remove unnecessary 64-bit read/write checks. Signed-off-by: Dhananjay Phadke Signed-off-by: Amit Kumar Salecha Signed-off-by: David S.
