[PATCH NEXT 1/2] linux/ethtool: Added macro ETH_FW_DUMP_DISABLE

[Manish Chopra <manish.chopra@qlogic.com>]

From: Manish chopra <manish.chopra@qlogic.com>

o flag field of ethtool_dump structure must be initialized by this macro
value that is zero, if the firmware dump is disabled.
by this we can get the firmware dump capability [enable/disable] via ethtool
