been undergoing test for some weeks. This improves the RX
mbuf handling to avoid system hang due to depletion. Thanks
to all those who have been testing the code, and to Beezar
Liu for the design changes.
Next the igb driver is updated for similar RX changes, but
also to add new features support for our upcoming i350 family
of adapters.

- this also includes virtualization support on these devices
Correct some vlan issues we were seeing in test, jumbo frames on vlans
did not work correctly, this was all due to confused logic around HW
filters, the new code should now work for all uses.
Important fix: when mbuf resources are depeleted, it was possible to
completely empty the RX ring, and then the RX engine would stall
forever. This is fixed by a flag being set whenever the refresh code
fails due to an mbuf shortage, also the local timer now makes sure
that all queues get an interrupt when it runs, the interrupt code
will then always call rxeof, and in that routine the first thing done
is now to check the refresh flag and call refresh_mbufs. This has been
verified to fix this type 'hang'. Similar code will follow in the other
drivers.
Finally, sync up shared code for the I350 support.
Thanks to everyone that has been reporting issues, and helping in the
debug/test process!!

- failure code in em_xmit got mangled along the way
and was not properly handling errors.
- local timer code had a leftover UNLOCK call that
should be removed.

the size can be smaller than the constant when you are
doing HW TAGGING, and you still need to process this
packet in a normal way. I'm not sure where the notion
to just return came from, but its wrong.

Second, correct the discard/refresh_mbufs code to behave
more like igb, there have been panics due to discards and
this should fix them.

disable ASPM L0S and L1 LINK states on 82573, 82574,
and 82583. The theory is that this is behind certain
hangs being experienced by some customers.
Also included a small optimization in the rxeof routine
that was in my internal code.
Change the PBA size for pchlan, it was incorrect.

- Fixes from John Baldwin: vlan shadow tables made per/interface,
make vlan hw setup only happen when capability enabled, and
finally, make a tuneable interrupt rate. Thanks John!
- Tweaked watchdog handling to avoid any false positives, now
detection is in the TX clean path, with only the final check
and init happening in the local timer.
- limit queues to 8 for all devices, with 82576 or 82580 on
larger machines it can get greater than this, and it seems
mostly a resource waste to do so. Even 8 might be high but
it can be manually reduced.
- use 2k, 4k and now 9k clusters based on the MTU size.
- rework the igb_refresh_mbuf() code, its important to
make sure the descriptor is rewritten even when reusing
mbufs since writeback clobbers things.

- Chasin down bogus watchdogs has led to an improved
design to this handling, the hang decision takes
place in the tx cleanup, with only a simple report
check in local_timer. Our tests have shown no false
watchdogs with this code.
- VLAN fixes from jhb, the shadow vfta should be per
interface, but as global it was not. Thanks John.
- Bug fixes in the support for new PCH2 hardware.
- Thanks for all the help and feedback on the driver,
changes to lem with be coming shortly as well.

- New client chipset support added
- em driver - fixes to 82574, limit queues to 1 but use MSIX
- em driver - large changes in TX checksum offload and tso
code, thanks to yongari.
- some small changes for watchdog issues.
- igb driver - local timer watchdog code was missing locking
this and a couple other watchdog related fixes.
- bug in rx discard found by Andrew Boyer, check for null pointer

- Add a single sysctl procedure to all three drivers to read an arbitrary
register (the register is passed as arg2). Use it to replace existing
routines in igb(4) that used a separate routine for each register, and
to add support for missing stats in em(4) and lem(4).
- Move the 'rx_overruns' and 'watchdog_timeouts' stats out of the MAC stats
section as they are driver stats, not MAC counters.
- Simplify the code that creates per-queue stats in igb(4) to use a single
loop and remove duplicated code.
- Properly read all 64 bits of the 'good octets received/transmitted' in
em(4) and lem(4).
- Actually read the interrupt count registers in em(4), and drop the
'host to card' sysctl stats from em(4) as they are not implemented in
any of the hardware this driver supports.
- Restore several stats to em(4) that were lost in the earlier stats
conversion including per-queue stats.
- Export several MAC stats in em(4) that were exported in igb(4) but not
in em(4).
- Export stats in lem(4) using individual sysctls as in em(4) and igb(4).

configuration function. For failed memory allocations, em(4)/lem(4)
called panic(9) which is not acceptable on production box.
igb(4)/ixgb(4)/ix(4) allocated the required memory in stack which
consumed 768 bytes of stack memory which looks too big.
To address these issues, allocate multicast array memory in device
attach time and make multicast configuration success under any
conditions. This change also removes the excessive use of memory in
stack.

Just showing some buffer allocation error is more appropriate
action for drivers. This should fix occasional panic reported on
em(4) when driver encountered resource shortage.

What this provides is support for the 'virtual function'
interface that a FreeBSD VM may be assigned from a host
like KVM on Linux, or newer versions of Xen with such
support.
When the guest is set up with the capability, a special
limited function 82576 PCI device is present in its virtual
PCI space, so with this driver installed in the guest that
device will be detected and function nearly like the bare
metal, as it were.
The interface is only allowed a single queue in this configuration
however initial performance tests have looked very good.
Enjoy!!
