- This adds a VM SRIOV interface, ixv, it is however
transparent to the user, it links with the ixgbe.ko,
but when ixgbe is loaded in a virtualized guest with
SRIOV configured this will be detected.
- Sync shared code to latest
- Many bug fixes and improvements, thanks to everyone
who has been using the driver and reporting issues.
the dev.fxp.%d.noflow tunable as the same effect can now be achieved with
ifconfig(8) by setting the flowcontrol media option as desired (besides
the tunable never having a chance to actually enable flow control support
so far).
In joint forces with: yongari
- Fix a bug where TCO_BOOT_STS was supposed to be cleared after
TCO_SECOND_TO_STS and not before.

functions, they are unused. Remove 'user' from npxgetuserregs()
etc. names.
For {npx,fpu}{get,set}regs(), always use pcb->pcb_user_save for FPU
context storage. This eliminates the need for ugly copying with
overwrite of the newly added and reserved fields in ucontext on i386
to satisfy alignment requirements for fpusave() and fpurstor().
pc98 version was copied from i386.

support multi-queue but the hardware limitation made it hard to
implement supporting multi-queue. Allocating more than necessary
vectors is resource waste and it can be added back when we
implement multi-queue support.
number of retry to be performed whenever controller found RX
descriptor was empty. RX empty interrupt is generated only when the
retry counter is over. Experimentation shows retrying RX descriptor
loading increased number of dropped frames under flow-control
enabled environments so disable it and have controller generate RX
empty interrupt as fast as it can.
While I'm here fix RXCSR_DESC_RT_CNT macro.
updates were being queued by pmap_kremove, but the queue wasn't being
flushed; as a result, the updates didn't happen until *after* the call
to pmap_invalidate_range, and old entries could stick around in the TLB.
Adding a PT_UPDATES_FLUSH() call immediately before pmap_invalidate_range
ensures that after the invalidation the TLB will be repopulated with the
correct new entries.

type into account (!), but clang's integrated assembler rightfully
complains about it.

the TLB which don't correspond to ptes with PG_V set; prior to this commit
I'm sometimes getting the wrong data when pages are loaded into the buffer
cache (they're being loaded, but the missing TLB invalidation is causing
the wrong data to be visible).
_HYPERVISOR_multicall, and create a new HYPERVISOR_multicall function which
invokes _HYPERVISOR_multicall and checks that the individual hypercalls all
succeeded.

unloaded repeatly. Attaching the USB pf is moved to usbus device's
attach.

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.
