Browse source 
DebugFS now will show fw_resource_count node.

FW Resource count

Original TGT exchg count[0]
current TGT exchg count[0]
original Initiator Exchange count[2048]
Current Initiator Exchange count[2048]
Original IOCB count[2078]
Current IOCB count[2067]
MAX VP count[254]
MAX FCF count[0]
