2013-06-18FMC: add a software carrier driverAlessandro Rubini
This fake carrier is designed to help FMC users understand how a carrier driver works, and to experiment the behaviour with EEPROM reprogramming (with a mezzanine driver commited later). This carrier can register up to 4 (fake) mezzanines. We have real carriers (both on PCI-E and VME), but they are bigger things and are not part of this submission.

2013-06-17tipc: change socket buffer overflow control to respect sk_rcvbufYing Xue
As per feedback from the netdev community, we change the buffer overflow protection algorithm in receiving sockets so that it always respects the nominal upper limit set in sk_rcvbuf. Instead of scaling up from a small sk_rcvbuf value, which leads to violation of the configured sk_rcvbuf limit, we now calculate the weighted per-message limit by scaling down from a much bigger value, still in the same field, according to the importance priority of the received message. To allow for administrative tunability of the socket receive buffer size, we create a tipc_rmem sysctl variable to allow the user to configure an even bigger value via sysctl command. It is a size of three (min/default/max) to be consistent with things like tcp_rmem. By default, the value initialized in tipc_rmem[1] is equal to the receive socket size needed by a TIPC_CRITICAL_IMPORTANCE message. This value is also set as the default value of sk_rcvbuf.
