mark controller's capability. Controllers that have jumbo frame
support sets MSK_FLAG_JUMBO, and controllers that does not support
checksum offloading for jumbo frames will set MSK_FLAG_JUMBO_NOCSUM.
For Fast Ethernet controllers it will set MSK_FLAG_FASTETHER and it
would be used in link state handling.
While here, disable Tx checksum offloading if jumbo frame is used
on controllers that does not have Tx checksum offloading capability
for jumbo frame(e.g. Yukon EC Ultra).
FE+ controller. Due to the severe silicon bugs for Yukon FE+,
88E3016 seems to require more workarounds. However I'm not sure
whether the workaround is PHY specific or only applicable to Yukon
FE+. The datasheet for the PHY is publicly available but it lacks
several details for the workaround used in this change. The
workaround information was obtained from Linux. Many thanks to
Yukon FE+ users who helped me add 88E3016 support.

ReleaseLockOwner operations analagous to what is already
in place for SetClientID and SetClientIDConfirm. These are
the five NFSv4 operations that do not use file handle(s),
so the checks are done using the NFSv4 root export entries
in /etc/exports.

Remove PAGE_SIZE alignment used in Rx buffer DMA tag creation. The
alignment restriction was used in old local jumbo allocator and
nfe(4) switched to UMA backed page allocator for jumbo frame.
This change should fix jumbo buffer allocation failure.

Note: this adds yet another copy of nfs_realign(). I will attempt to refactor

sleep waiting for conditions when the lock may be granted.
To prevent lf_setlock() from accessing possibly freed memory, add reference
counting to the struct lockf_entry. Bump refcount around the sleep.
Make lf_free_lock() return non-zero when structure was freed, and use
this after the sleep to return EINTR to the caller. The error code might
need a clarification, but we cannot return success to usermode, since
the lock is not owned anymore.

In the original MPSAFE TTY code, I changed the behaviour by returning
EBUSY. I thought this made more sense, because it's basically a race to
see who gets the TTY first.
It turns out this is not a good change, because it also causes EBUSY to
be returned when another process is closing the TTY. This can happen
during startup, when /etc/rc (or one of its children) is still busy
draining its data and /sbin/init is attempting to open the TTY to spawn
a getty.

This includes the addition of a new flag "-4" that will force
use of the experimental server with nfsv4 support in it. This
commit also adds two new man pages to the repository that are
NFSv4 specific. One describes the file used by the server to
restart nfsv4 services safely. The other is a brief overview
of nfsv4 and its setup.

to optionally have overlapping unit numbers if attached in different
vnets.
At this stage if_loop is the only clonable ifnet class that has been
extended to allow for such overlapping allocation of unit numbers, i.e.
in each vnet it is possible to have a lo0 interface. Other clonable ifnet
classes remain to operate with traditional semantics, i.e. each instance
of a clonable ifnet will be assigned a globally unique unit number,
regardless in which vnet such an ifnet becomes instantiated.
While here, garbage collect unused _lo_list field in struct vnet_net,
as well as improve indentation for #defines in sys/net/vnet.h.
The layout of struct vnet_net has changed, therefore bump
__FreeBSD_version.
This change has no functional impact on nooptions VIMAGE kernel builds.

So far the udp_tun_func_t had been (ab)using inp_ppcb for udp in kernel
tunneling callbacks. Move that into the udpcb and add a field for flags
there to be used by upcoming changes instead of sticking udp only flags
into in_pcb flags2.
