Based on RFC3810 6.2, we also need to check the hop limit and router alert
option besides source address.

Hangbin Liu 0d68fc4f12 infiniband: make sure the src net is infiniband when create new link 
When we create a new infiniband link with uninfiniband device, e.g. `ip link
add link em1 type ipoib pkey 0x8001`. We will get a NULL pointer dereference
cause other dev like Ethernet don't have struct ib_device.

The code path is:
rtnl_newlink
  |-- ipoib_new_child_link
        |-- __ipoib_vlan_add
              |-- ipoib_set_dev_features
                    |-- ib_query_device

Fix this bug by make sure the src net is infiniband when create new link.

Hangbin Liu 4249357010 tcp: Add TCP_USER_TIMEOUT negative value check 
TCP_USER_TIMEOUT is a TCP level socket option that takes an unsigned int. But
patch "tcp: Add TCP_USER_TIMEOUT socket option"(dca43c75) didn't check the negative
values. If a user assign -1 to it, the socket will set successfully and wait
for 4294967295 miliseconds. This patch add a negative value check to avoid
this issue.
