Linux 4.10 API接口变更
1. 删除了API函数__genl_register_family_with_ops(family, ops, n_ops).
2. 删除了API宏函数genl_register_family_with_ops(family, ops).

genetlink: statically initialize families
Instead of providing macros/inline functions to initialize
the families, make all users initialize them statically and
get rid of the macros.
This reduces the kernel code size by about 1.6k on x86-64
(with allyesconfig).

genetlink: no longer support using static family IDs
Static family IDs have never really been used, the only
use case was the workaround I introduced for those users
that assumed their family ID was also their multicast
group ID.
Additionally, because static family IDs would never be
reserved by the generic netlink code, using a relatively
low ID would only work for built-in families that can be
registered immediately after generic netlink is started,
which is basically only the control family (apart from
the workaround code, which I also had to add code for so
it would reserve those IDs)
Thus, anything other than GENL_ID_GENERATE is flawed and
luckily not used except in the cases I mentioned. Move
those workarounds into a few lines of code, and then get
rid of GENL_ID_GENERATE entirely, making it more robust.

Linux 3.13.0 API接口变更
删除了API函数genl_register_ops() / genl_unregister_ops()
git提交日志链接:

# 内核开发者日志
genetlink: remove genl_register_ops/genl_unregister_ops
genl_register_ops() is still needed for internal registration,
but is no longer available to users of the API.
