From: Raja Mani <rmani@xxxxxxxxxxxxxxxx>
Firmware reports the below ARP offload related information
while sending the target statistic event to the host.
* Number of ARP packets received.
* Number of packets matched with the device IP addr.
* Number of ARP response packet sent to the remote.
This patch adds the additional debug prints in debugfs
entry tgt_stats. It will be useful to know the ARP offload
execution status.
