From ee7255ada313a6db99be47ce174b0bfb8295a041 Mon Sep 17 00:00:00 2001 From: Anish Bhatt Date: Tue, 18 Nov 2014 19:09:51 -0800 Subject: [PATCH] cxgb4i : Don't block unload/cxgb4 unload when remote closes TCP connection cxgb4i was returning wrong error and not releasing module reference if remote end abruptly closed TCP connection. This prevents the cxgb4 network module from being unloaded, further affecting other network drivers dependent on cxgb4 Sending to net as this affects all cxgb4 based network drivers.
