The X520 family of network devices, with the 82599 chip, support a
small number of Intel-verified SFP+ modules on their NICs. To maintain
stability and quality, the current devices restrict untested 3rd party
SFP+ modules.
This patch introduces a module parameter for ixgbe to allow these untested
modules at the user's peril. It also includes a warning to the syslog
alerting users that the modules aren't supported, and results may
vary.

TCP RST mechanism is broken in TCP md5(RFC2385). When
connection is gone, md5 key is lost, sending RST
without md5 hash is deem to ignored by peer. This can
be a problem since RST help protocal like bgp to fast
recove from peer crash.
In most case, users of tcp md5, such as bgp and ldp,
have listener on both sides to accept connection from peer.
md5 keys for peers are saved in listening socket.
There are two cases in finding md5 key when connection is
lost:
1.Passive receive RST: The message is send to well known port,
tcp will associate it with listner. md5 key is gotten from
listener.
2.Active receive RST (no sock): The message is send to ative
side, there is no socket associated with the message. In this
case, finding listener from source port, then find md5 key from
listener.
we are not loosing sercuriy here:
packet is checked with md5 hash. No RST is generated
if md5 hash doesn't match or no md5 key can be found.

We don't check for NULL consistently in __xfrm6_output(). If "x" were
NULL here it would lead to an OOPs later. I asked Steffen Klassert
about this and he suggested that we remove the NULL check.

This patch makes sure we use appropriate memory barriers before
publishing tp->md5sig_info, allowing tcp_md5_do_lookup() being used from
tcp_v4_send_reset() without holding socket lock (upcoming patch from
Shawn Lu)
Note we also need to respect rcu grace period before its freeing, since
we can free socket without this grace period thanks to

There is no limit on number of MD5 keys an application can attach to a
tcp socket.
This patch adds a per tcp socket limit based
on /proc/sys/net/core/optmem_max
With current default optmem_max values, this allows about 150 keys on
64bit arches, and 88 keys on 32bit arches.

In order to be able to support proper RST messages for TCP MD5 flows, we
need to allow access to MD5 keys without locking listener socket.
This conversion is a nice cleanup, and shrinks size of timewait sockets
by 80 bytes.
IPv6 code reuses generic code found in IPv4 instead of duplicating it.
Control path uses GFP_KERNEL allocations instead of GFP_ATOMIC.
