- Use NFSD_MONOSEC (which maps to time_uptime) instead of the seconds
portion of wall-time stamps to manage timeouts on events.
- Remove unused nd_starttime from the per-request structure in the new
NFS server.
- Use nanotime() for the modification time on a delegation to get as
precise a time as possible.
- Use time_second instead of extracting the second from a call to
getmicrotime().

All bugs are: mine
The changes are:
- the microcore code loaded into the NAE has to be byteswapped
in LE
- the descriptors in memory for a P2P NAE descriptor has to be
byteswapped in LE
- the m_data pointer is already cacheline aligned, so the
unnecessary m_adj to cacheline size can be removed
- fix mask used to obtain physical address from the Tx freeback
descriptor
- fix a compile error in code under #ifdef

Support few more versions of board firmware. In case the security

reading registers from other CPUs. As it turns out, the hardware doesn't
really like concurrent IPI'ing causing adverse effects. Also the thought
deadlock when using this spin lock here and the targeted CPU(s) are also
holding or in case of nested locks can't actually happen. This is due to
the fact that on sparc64, spinlock_enter() only raises the PIL but doesn't
disable interrupts completely. Thus direct cross calls as used for the
register reading (and all other MD IPI needs) still will be executed by
the targeted CPU(s) in that case.

comconsole setup. Previously the hint would be set when if you set a
custom port, but it would not be updated if you later set a custom speed.
Also, leave the hw.uart.console hint mutable so it can be overridden or
unset by the user if needed.

By setting dev.netmap.fwd=1 (or enabling the feature with a per-ring flag),
packets are forwarded between the NIC and the host stack unless the
netmap client clears the NS_FORWARD flag on the individual descriptors.
This feature greatly simplifies applications where some traffic
(think of ARP, control traffic, ssh sessions...) must be processed
by the host stack, whereas the bulk is handled by the netmap process
which simply (un)marks packets that should not be forwarded.
The default is chosen so that now a netmap receiver operates
in a mode very similar to bpf.
Of course there is no free lunch: traffic to/from the host stack
still operates at OS speed (or less, as there is one extra copy in
one direction).
HOWEVER, since traffic goes to the user process before being
reinjected, and reinjection occurs in a user context, you get some
form of livelock protection for free.
Ext2fs uses unsigned fields in its dinode struct.
FreeBSD can have negative values in some of those
fields and the inode is meant to interact with the
system so we have never respected the unsigned
nature of most of those fields.
Block numbers and the NFS generation number do
not need to be signed so redefine them as
unsigned to better match the on-disk information.

Add a missing 0 to the mask for byte0 of C_SIZE.
The previous mask (0xc) worked except that the last 0-1536K of the disk
could not be accessed since we were shifting the (wrong) bits we did
mask off the right edge.
Testing with fsx has revealed problems and in order to
hunt the bugs properly we need reduce the complexity.
This seems to help but is not a complete solution.

logic (refer to [1] for associated discussion). snd_cwnd and snd_wnd are
unsigned long and on 64 bit hosts, min() will truncate them to 32 bits and could
therefore potentially corrupt the result (although under normal operation,
neither variable should legitmately exceed 32 bits).

gcc handles -symbolic by passing -Bsymbolic through to ld. clang ignores
-symbolic and thus invokes ld without -Bsymbolic which leads to some symbols
not being properly linked in loader.efi. Fix this by using -Wl,-Bsymbolic which
passes -Bsymbolic to ld in both the gcc and clang cases.

This is easily possible now that the TX is protected by a single
lock, rather than a per-TXQ (and thus per-TID) lock.
Only set CLRDMASK if none of the destinations are filtered.
This likely will need some tuning when it comes time to do UASPD/PS-POLL
TX, however at that point it should be manually set anyway.
Tested:
* AR9280, STA mode
TODO:
* More thorough testing in AP mode
* test other chipsets, just to be safe/sure.
