There is no good reason to not support userspace specifying the network namespace during device creation, and it makes it easier to create a network device and pass it to a child network namespace with a well known name. We have to be careful to ensure that the target network namespace for the new device exists through the life of the call. To keep that logic clear I have factored out the network namespace grabbing logic into rtnl_link_get_net. In addtion we need to continue to pass the source network namespace to the rtnl_link_ops.newlink method so that we can find the base device source network namespace. Signed-off-by: NEric W.

Vitezslav Samel discovered that since 2.6.30.4+ active FTP can not work over NAT. The "cause" of the problem was a fix of unacknowledged data detection with NAT (commit a3a9f79e). However, actually, that fix uncovered a long standing bug in TCP conntrack: when NAT was enabled, we simply updated the max of the right edge of the segments we have seen (td_end), by the offset NAT produced with changing IP/port in the data. However, we did not update the other parameter (td_maxend) which is affected by the NAT offset. Thus that could drift away from the correct value and thus resulted breaking active FTP. The patch below fixes the issue by *not* updating the conntrack parameters from NAT, but instead taking into account the NAT offsets in conntrack in a consistent way. (Updating from NAT would be more harder and expensive because it'd need to re-calculate parameters we already calculated in conntrack.)

The 5785 does not use the RXC reference clock. Turning it off is desirable as it saves power. By default, the 50610 enables the RXC reference clock and the 50610M disables it. Presumably this is one of the reasons why the hardware architect chose one over the other. Adding a "rx reference clock disable" flag is not the ideal way to describe the option, as it would force the MAC using a 50610M to set the flag. Ideally we want the flags to represent opt-in behavior that deviates from hardware defaults. Furthermore, the lack of a "disable" flag implies that the requester wants the rx reference clock enabled, which doesn't necessarily follow. By presenting the option as a passive statement (rx reference clock unused) rather than a command, I hope to convey an opt-in option to disable the rx reference clock that falls back to hardware defaults if not set. A secondary benefit of this is that it keeps the intelligence about phy defaults in the broadcom module where it belongs and allows the broadcom module more latitude should a bug arise.

Broadcom 50610M parts changed the default definitions of the RGMII mode shadow register. The 5785 needs the RGMII mode selection bits [4:3] cleared. The default value of the remaining bits in this register are zero. Rather than unnecessarily burn an extra bit in the dev_flags member in an attempt to enumerate all possible combinations, this patch take a more course grained approach and labels the option as "clear all bits".

RDS currently supports a GET_MR sockopt to establish a memory region (MR) for a chunk of memory. However, the fastreg method ties a MR to a particular destination. The GET_MR_FOR_DEST sockopt allows the remote machine to be specified, and thus support for fastreg (aka FRWRs). Note that this patch does *not* do all of this - it simply implements the new sockopt in terms of the old one, so applications can begin to use the new sockopt in preparation for cutover to FRWRs.

So when we implement new protocol support we should keep such a detail in mind (which is easy to forget about). Lets introduce DECLARE_SOCKADDR helper which check if storage unit is not overfowed at build time. Eventually inet_getname is switched to use DECLARE_SOCKADDR (to show example of usage).
