2012-02-04enic: Enable support for multiple hardware receive queuesNeel Patel1-2/+2
This patch enables support for multiple receive queues. If multiple receive queues are used ingress traffic is hashed into one of the receive queues based on IP or TCP or both headers. The max number of supported receive queues per vnic is 8.

We've moving to a model where dst_entry objects to not have a reference to the associated neighbour entry, instead such neighbours must be looked up on-demand.

2012-02-01ixgbe: Add module parameter to allow untested and unsafe SFP+ modulesPeter P Waskiewicz Jr3-3/+20
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.

2012-02-01tcp: md5: RST: getting md5 key from listenerShawn Lu2-5/+83
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. Signed-off-by: Shawn Lu <shawn.lu@ericsson.com> Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

There is no limit on number of MD5 keys an application can attach to a tcp socket.

2012-01-31tcp: md5: rcu conversionEric Dumazet5-335/+141
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.
