Passing "-x lazyload" to dtrace -G during compilation causes dtrace(1) to
not link drti.o into the output object file, so the USDT probes are not created
during process startup. Instead, dtrace(1) will automatically discover and
create probes on the process' behalf when attaching.

dmar_map_entry. Non-zero offset both increases the required mapping
size, which is handled in dmar_bus_dmamap_load_something1(), and makes
it possible that allocated range crosses boundary, which needs a check
in dmar_gas_match_one().

This significantly improves performance on multi-core servers where there
is any kind of IPv4 reassembly going on.
glebius@ would like to see the locking moved to be attached to the reassembly
bucket, which would make it per-bucket + per-VNET, instead of being global.
I decided to keep it global for now as it's the minimal useful change;
if people agree / wish to migrate it to be per-bucket / per-VNET then please
do feel free to do so. I won't complain.
Thanks to Norse Corp for giving me access to much larger servers
to test this at across the 4 core boxes I have at home.

- Extend the number of available subtypes for Ethernet media by using some
of the ifmedia word's option bits to help denote subtypes. As a result, the
number of possible Ethernet subtype values increases from 31 to 511.
- Use some of those new values to define new media types.
- lacp_compose_key() recgonizes the new Ethernet media types added.
(Change made as required by a comment in if_media.h)
- New ioctl, SIOGIFXMEDIA, to handle getting the new extended media types.
SIOCGIFMEDIA is retained for backwards compatibility.
- Changes to ifconfig to allow it to handle the new extended media types.

ipfilter code as userland application. To reduce kernel structure knowledge
include if_var.h only if a file is compiled with _KERNEL defined.
In !_KERNEL case, provide our own definition of struct ifnet, that will
satisfy ipftest(1). This was already done earlier to struct ifaddr in
r279029. Protect the definition with _NET_IF_VAR_H_, since kernel part
of ipfilter may include if_var.h and ip_compat.h.

o Now, netstat/mroute6.c no longer needs to kvm_read(3) struct ifnet, and
no longer needs to include if_var.h
Note that this change is far from being a complete move of IPv6 multicast
routing to a proper API. Other structures are still dumped into their
sysctls as is, requiring userland application to #define _KERNEL when
including ip6_mroute.h and then call kvm_read(3) to gather all bits and
pieces. But fixing this is out of scope of the opaque ifnet project.
