cfg80211 module prints a lot of messages like below. Actually printing
once is acceptable but sometimes it will print again and again, it looks
very annoying. It is better to change these detail messages to debugging
only.

Would it make sense to annotate checks before such function calls
as "UNLIKELY"?

Hi,
When we tested network with following case, found there is
regression with stable 4.1 kernel, connect() returns EADDRNOTAVAIL,
while a pretty old kernel 3.8 doesn't. anybody knows about this issue
and if it was fixed later ? (I am looking for devices and will do a

To whom it may concern:

Now that IP1000A chips are supported by dl2k driver, the buggy ipg
driver can be removed. The ipg driver loses packets under load and then
completely stops transmitting data.

Add support for IP1000A chips to dl2k driver.
IP1000A chip looks like a TC9020 with integrated PHY.
This allows IP1000A chips to work reliably because the ipg driver is
buggy - it loses packets under load and then completely stops
transmitting data.

Sending ICMP packets with raw sockets ends up in the SNMP counters
logging the type as the first byte of the IPv4 header rather than
the ICMP header. This is fixed by adding the IP Header Length to
the casting into a icmphdr struct.
