From 99ef563901a18d44a6c2eadd2b958e2e83aeca51 Mon Sep 17 00:00:00 2001 From: Vasanthy Kolluri Date: Thu, 24 Jun 2010 10:50:00 +0000 Subject: enic: Use a lighter reset operation for enic devices The port profile information for a dynamic enic device is set by the upper layers, that are oblivious to the device reset operation. We do not want a reset operation erase the network state of a dynamic enic device as there is no way to set up the port profile information again. Hence a lighter reset operation called hang reset is used. Hang reset, unlike soft reset does not reset the network state and resets the host side state only.
