Message-ID: <1406895452-29514-4-git-send-email-sathya.perla@emulex.com>

Subject: [PATCH net-next 3/3] be2net: support deleting FW dump via ethtool (only for Lancer)
From: Kalesh AP <kalesh.purayil@...lex.com>
This patch adds support to delete an existing FW-dump in Lancer via ethtool.
Initiating a new dump is not allowed if a FW dump is already present in the
adapter. The existing dump has to be first explicitly deleted.
