After introducing dellink handling and per-net namespace management
for IPv4 and IPv6 sockets, extend rxe to create and destroy RDMA links
within each network namespace.
With this change, RDMA links can be instantiated both in init_net and
in other network namespaces. The lifecycle of the RDMA link is now tied
to the corresponding namespace and is properly cleaned up when the
namespace or link is removed.
This ensures rxe behaves correctly in multi-namespace environments and
keeps socket and RDMA link resources consistent across namespace
creation and teardown.

We typically place defines at the beginning of a file and avoid undefining
them. The undef directive is mainly used when a macro is defined inside a
function.
Defining macros locally helps clarify the intent behind specific values.
By pairing the #define with a trailing #undef, we gain the descriptive
benefits of the macro while maintaining strict control over its visibility.
I will put the definition of the MACRO in the function, following your
advice.
Thanks.
