1317240bac Add a couple of summary paragraphs at the head of mbuf_tags(9) to
indicate how m_tags might be used, and what their high level properties
are.  This may help developers using tags get a more clear picture
before delving into the technical details of ABI cookies and API calls.

42c5607501 Remove inlined m_tag_free(). Rename _m_tag_free() to m_tag_free()
and make it visible (same way as in OpenBSD). Describe usage in manpage.

This change is useful for creating custom free methods, which
call default free method at their end.

While here, make malloc declaration for mbuf tags more informative.

d6a8d58875 Add an additional struct inpcb * argument to pfil(9) in order to enable
passing along socket information. This is required to work around a LOR with
the socket code which results in an easy reproducible hard lockup with
debug.mpsafenet=1. This commit does *not* fix the LOR, but enables us to do
so later. The missing piece is to turn the filter locking into a leaf lock
and will follow in a seperate (later) commit.

This will hopefully be MT5'ed in order to fix the problem for RELENG_5 in
forseeable future.

c21fd23260 Always compile PFIL_HOOKS into the kernel and remove the associated kernel
compile option.  All FreeBSD packet filters now use the PFIL_HOOKS API and
thus it becomes a standard part of the network stack.

If no hooks are connected the entire packet filter hooks section and related
activities are jumped over.  This removes any performance impact if no hooks
are active.

Both OpenBSD and DragonFlyBSD have integrated PFIL_HOOKS permanently as well.

4d855643d1 Clarify what the lockfunc is used for. When it will be called and
when it won't be called.  The old wording was correct, but not
sufficiently specific to understand when and how it would be called.
The new wording describes the current implementation's usage (which
should be updated if other appropriate times are decided upon),
specifically that it is called only when the load operation is
deferred to keep the locking state consistent.  When the operation
isn't deferred, the calling routine is assumed to have a coherent
locking world.

95929b661e Even in a 80 column, fixed point font, there's plenty of room for all
the arguments to bus_dmamap_load, so don't use '...' but list the
actual args.  '...' usually means a variable number of args (cf
printf(3)), but bus_dmamap_load takes a fixed number of arguments.
