printk() is the raw way to print output and should be avoided.
For drivers with defined "struct device object", dev_*macro() is
prefer and for "struct netdevice object", netdev_*macro() is prefer over
dev_*macro() to standardize the output format within the subsystem.
If no "struct device object" is defined prefer pr_*macro() over printk().
This patch Replace printk having a log level with the appropriate output
format according to the order of preference.

Changes in v3
*In version2 net_*macro_ratelimited was used which is not helping in
standardizing the output format.
Changes in v2
*change the subject line, driver name was wrong.

I'm sorry. I really hate to do this to you... But the right thing here
is to use net_dbg_ratelimited() but get rid of the if (net_ratelimit())
check. So it looks like this:
if (!(keyidx & (1 << 5))) {
net_dbg_ratelimited(skb->dev,
"CCMP: received packet without ExtIV flag from %pM\n",
hdr->addr2);
}
Sorry again, when I looked at it before I just replied what my fast
thinking lizard brain said instead of taking time to look at what I was
saying.
regards,
dan carpenter

I don't think that net_dbg_ratelimited wants a skb->dev argument. The
various definitions in include/linux/net.h just have fmt as the first
argument.

Ah.... That's fine then. Don't worry about it.
