- Select a tag gains ability to optionally save new tags
off in the timewait system.
- When looking up associations do not give back a stcb that
is in the about-to-be-freed state, and instead continue
looking for other candiates.
- New function to query to see if value is in time-wait.
- Timewait had a time comparison error that caused very
few vtags to actually stay in time-wait.
- When setting tags in time-wait, we now use the time
requested NOT a fixed constant value.
- sstat now gets the proper associd when we do the query.
- When we process an association, we expect the tag chosen
(if we have one from a cookie) to be in time-wait. Before
we would NOT allow the assoc up by checking if its good.
In theory this should have caused almost all assoc not
to come up except for the time-comparison bug above (this
bug was hidden by the time comparison bug :-D).
- Don't save tags for nonce values in the time-wait cache
since these are used only during cookie collisions and do
not matter if they are unique or not.

changes:
01 - Enhanced LRO:
LRO feature is extended to support multi-buffer mode. Previously,
Ethernet frames received in contiguous buffers were offloaded.
Now, frames received in multiple non-contiguous buffers can be
offloaded, as well. The driver now supports LRO for jumbo frames.
02 - Locks Optimization:
The driver code was re-organized to limit the use of locks.
Moreover, lock contention was reduced by replacing wait locks
with try locks.
03 - Code Optimization:
The driver code was re-factored to eliminate some memcpy
operations. Fast path loops were optimized.
04 - Tag Creations:
Physical Buffer Tags are now optimized based upon frame size.
For better performance, Physical Memory Maps are now re-used.
05 - Configuration:
Features such as TSO, LRO, and Interrupt Mode can be configured
either at load or at run time. Rx buffer mode (mode 1 or mode 2)
can be configured at load time through kenv.
06 - Driver Statistics:
Run time statistics are enhanced to provide better visibility
into the driver performance.
07 - Bug Fixes:
The driver contains fixes for the problems discovered and
reported since last submission.
08 - MSI support:
Added Message Signaled Interrupt feature which currently uses 1
message.
09 Removed feature:
Rx 3 buffer mode feature has been removed. Driver now supports 1,
2 and 5 buffer modes of which 2 and 5 buffer modes can be used
for header separation.
10 Compiler warning:
Fixed compiler warning when compiled for 32 bit system.

RTL8211B(L) is RealTek's new gigabit PHY. The PHY has several
features including crossover correction, polarity correction as
well as supporting triple speed(10/100/1000bps). Data transfer
between MAC and PHY is via RGMII for 1000baseT, MII for
10baseT/100baseTX.
Unfortunately, RealTek used the same model number for RTL8211B(L)
PHY so there is no way to discriminate between RTL8211B(L) and its
predecessors. ATM RTL8211B uses revision number 2 so checking the
revision number seems to be only way to identify it.

- Add mac_inet6.c and add explicit entry point mac_netinet6_nd6_send()

point.
- Add expliict entry point mac_netinet_arp_send() for ARP packet

rather than using a generic link layer entry point.
- Remove previous genering link layer entry point,
mac_mbuf_create_linklayer() as it is no longer used.
- Add implementations of new entry points to various policies, largely
by replicating the existing link layer entry point for them; remove
old link layer entry point implementation.
- Make MAC_IFNET_LOCK(), MAC_IFNET_UNLOCK(), and mac_ifnet_mtx global
to the MAC Framework rather than static to mac_net.c as it is now

userland preemption directly from hardclock() via sched_clock() when a
thread uses up a full quantum instead of using a periodic timeout to cause
a userland preemption every so often. This fixes a potential deadlock
when IPI_PREEMPTION isn't enabled where softclock blocks on a lock held
by a thread pinned or bound to another CPU. The current thread on that
CPU will never be preempted while softclock is blocked.
Note that ULE already drives its round-robin userland preemption from
sched_clock() as well and always enables IPI_PREEMPT.

a private softc list is needed neither for tracking clones in general
nor for destroying all clones before the module unload -- if_clone
takes care of all that. (Note that some other interface drivers do
need a softc list to be able to scan it for their private purposes.)

Currently, mount_nfs converts these "-o" options from strings

This change will allow us in future to pass these mount options
