Remove the NATM framework including the en(4), fatm(4), hatm(4), and

patm(4) devices. Maintaining an address family and framework has real costs when we make infrastructure improvements. In the case of NATM we support no devices manufactured in the last 20 years and some will not even work in modern motherboards (some newer devices that patm(4) could be updated to support apparently exist, but we do not currently have support). With this change, support remains for some netgraph modules that don't require NATM support code. It is unclear if all these should remain, though ng_atmllc certainly stands alone. Note well: FreeBSD 11 supports NATM and will continue to do so until at least September 30, 2021. Improvements to the code in FreeBSD 11 are certainly welcome. Reviewed by: philip Approved by: harti

sys/dev: Replace zero with NULL for pointers.

2017-02-20T03:43:12Z

Makes things easier to read, plus architectures may set NULL to something different than zero. Found with: devel/coccinelle MFC after: 3 weeks

sys/dev: minor spelling fixes.

2016-05-03T03:41:25Z

Most affect comments, very few have user-visible effects.

sys/dev: extend use of the howmany() macro when available.

2016-04-26T15:03:15Z

We have a howmany() macro in the header that is convenient to re-use as it makes things easier to read.

sys/dev: use our nitems() macro when it is avaliable through param.h.

No functional change, only trivial cases are done in this sweep, Drivers that can get further enhancements will be done independently. Discussed in: freebsd-current

Cleanup unnecessary semicolons from the kernel.

Found with devel/coccinelle.

Fix LDADD/DPADD that should be LIBADD.

To ease changes to underlying mbuf structure and the mbuf allocator, reduce

the knowledge of mbuf layout, and in particular constants such as M_EXT, MLEN, MHLEN, and so on, in mbuf consumers by unifying various alignment utility functions (M_ALIGN(), MH_ALIGN(), MEXT_ALIGN() in a single M_ALIGN() macro, implemented by a now-inlined m_align() function: - Move m_align() from uipc_mbuf.c to mbuf.h; mark as __inline. - Reimplement M_ALIGN(), MH_ALIGN(), and MEXT_ALIGN() using m_align(). - Update consumers around the tree to simply use M_ALIGN(). This change eliminates a number of cases where mbuf consumers must be aware of whether or not mbufs returned by the allocator use external storage, but also assumptions about the size of the returned mbuf. This will make it easier to introduce changes in how we use external storage, as well as features such as variable-size mbufs.
