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.
11 Copyright notice:

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.

mii_anegticks to MII_ANEGTICKS_GIGE and use it. Previously it used

autonegotiation process at 1000bps.
o Reset autonegotation timer if media option is not IFM_AUTO or we
got a valid link.
o Announce link loss right after it happends.
o Autonegiation is retried every mii_anegticks seconds.
o Report link state changes right after setting autonegotiation.
Blade 1500/SX1500 boards have inherited the firmware bug of the
AX1105 mainboards to not include an interrupt map entry for the
parallel port controller (for the AX1105 the heuristic code for
E450s probably erroneously kicks in and guesses an interrupt).

Framework by moving from mac_mbuf_create_netlayer() to more specific
entry points for specific network services:
- mac_netinet_firewall_reply() to be used when replying to in-bound TCP
segments in pf and ipfw (etc).
- Rename mac_netinet_icmp_reply() to mac_netinet_icmp_replyinplace() and
add mac_netinet_icmp_reply(), reflecting that in some cases we overwrite
a label in place, but in others we apply the label to a new mbuf.

in the TrustedBSD MAC Framework:
- Add mac_atalk.c and add explicit entry point mac_netatalk_aarp_send()
for AARP packet labeling, rather than using a generic link layer
entry point.
- Add mac_inet6.c and add explicit entry point mac_netinet6_nd6_send()
for ND6 packet labeling, rather than using a generic link layer entry
point.
- Add expliict entry point mac_netinet_arp_send() for ARP packet
labeling, and mac_netinet_igmp_send() for IGMP packet labeling,
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
needed outside of mac_net.c.

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.)

and MOPT_ASYNC.
Currently, mount_nfs converts these "-o" options from strings
to MNT_ flags via getmntopts(),
and passes the flags from userspace to the kernel.
This change will allow us in future to pass these mount options
as strings directly to the kernel via nmount() when doing NFS mounts.

(1) This makes the behavior consistent with mount(2).
(2) This makes update mounts on the root file system work properly.
(3) The explicit checks for MNT_ROOTFS in src/sbin/fsck_ffs/main.c
and src/usr.sbin/mountd/mountd.c which were put in to
eliminate errors during update mounts on the root file system
can be removed.
The only place were MNT_ROOTFS can be validly set
is inside the kernel, i.e. with vfs_mountroot_try().
