when we start using RSS
- move ether_ifdetach to before the port lock gets deinitialized to avoid
hang in the case where there are BPF peers (cxgb_ioctl is called indirectly
when BPF peers are present)
- don't call t3_mac_reset if multiport is set, this was causing tx errors
by misconfiguring the MAC on the 4-port
- change V_TXPKT_INTF to use txpkt_intf as the interfaces are not contiguous
- free the mbuf immediately in the case where the payload is small enough to be copied

driver attaches to each cpu device and creates a sysctl node in that
device's sysctl context (dev.cpu.N.temperature). When invoked, the
handler binds to the appropriate CPU to ensure a correct reading.

Without this the PHY wouldn't work as expected. This should fix
dual-boot Windows XP machine where RealTek Windows drivers put the
PHY in power down mode during shutdown. The magic PHY register
accesses come from RealTek driver. No datasheets mention the magic
PHY registers.
In general, the PHY wakeup code should go into PHY driver. However it
seems that it only apply to RTL8169S single chip and it would be
another hack if we have rgephy(4) check what parent driver/chip model
is attached.

differ in their details with calls to a new function, ehci_hcreset(),
that performs the reset.
The original sequences either had no delay or a 1ms delay between
telling the controller to stop and asserting the controller reset
bit. One instance of the original reset sequence waited for the
controller to indicate that its reset was complete before continuing,
but the other two immediately let the subsequent code execute. The
latter is a problem on some hardware, because a read of the HCCPARAMS
register returns an incorrect value while the reset is in progress,
which triggers an infinite loop in ehci_pci_givecontroller(), which
hangs the system on shutdown.
The reset sequence in ehci_hcreset() starts with the most complete
instance from the original code, which contains a loop to wait for
the controller to indicate that its reset is complete. This appears
to be the correct thing to do according to "Enhanced Host Controller
Interface Specification for Universal Serial Bus" revision 1.0,
section 2.3.1. Add another loop to wait for the controller to
indicate that it has stopped before setting the HCRESET bit. This
is required by the section 2.3.1 in the specification, which says
that setting HCRESET before the controller has halted "will result
in undefined behaviour".

requiring DC_TX_ALIGN or DC_TX_COALESCE, which was previously done
in dc_start_locked(), into dc_encap().
o In dc_encap():
- If m_defrag() fails just drop the packet like other NIC drivers
do. This should only happen when there's a mbuf shortage, in which
case it was possible to end up with an IFQ full of packets which
couldn't be processed as they couldn't be defragmented as they
were taking up all the mbufs themselves. This includes adjusting
dc_start_locked() to not trying to prepend the mbuf (chain) if
dc_encap() has freed it.
- Likewise, if bus_dmamap_load_mbuf() fails as dc_dma_map_txbuf()
failed, free the mbuf possibly allocated by the above call to
m_defrag() and drop the packet.
o In dc_txeof():
- Don't clear IFF_DRV_OACTIVE unless there are at least 6 free TX
descriptors. Further down the road dc_encap() will bail if there
are only 5 or fewer free TX descriptors, causing dc_start_locked()
to abort and prepend the dequeued mbuf again so it makes no sense
to pretend we could process mbufs again when in fact we won't.
While at it replace this magic 5 with a macro DC_TX_LIST_RSVD.
- Just always assign idx to sc->dc_cdata.dc_tx_cons; it doesn't
make much sense to exclude the idx == sc->dc_cdata.dc_tx_cons
case.
o In dc_dma_map_txbuf() there's no need to set sc->dc_cdata.dc_tx_err
to error if the latter is != 0, bus_dmamap_load_mbuf() already
returns the same error value in that case anyway.
o For less overhead, convert to use bus_dmamap_load_mbuf_sg() for
loading RX buffers.
o Remove some banal and/or outdated comments.

the fast or safe/slow method is in use. Fast remains at 1000, slow is
now at 850 (always preferred to TSC). Since the HPET has proven slower
than ACPI-fast on some systems, drop its quality to 900. In the future,
it is hoped that HPET performance will improve as it is the main
timer Intel supports. HPET may move back to 2000 in -current once RELENG_7
is branched to ensure that it gets tested.

- Remove NET_NEEDS_GIANT() and associate SYSINITSs used by it to force
debug.mpsafenet=0 if non-MPSAFE protocols are compiled into the kernel.
- Remove logic to automatically flag interrupt handlers as non-MPSAFE if
debug.mpsafenet is set for an INTR_TYPE_NET handler.
- Remove logic to automatically flag netisr handlers as non-MPSAFE if
debug.mpsafenet is set.
- Remove references in a few subsystems, including NFS and Cronyx drivers,
which keyed off debug_mpsafenet to determine various aspects of their own
locking behavior.
- Convert NET_LOCK_GIANT(), NET_UNLOCK_GIANT(), and NET_ASSERT_GIANT into
no-op's, as their entire behavior was determined by the value in
debug_mpsafenet.
- Alias NET_CALLOUT_MPSAFE to CALLOUT_MPSAFE.

This is taken from PR 110681, although what URATAN Shigenobu describes
there is different than the pathology that I have been seeing. I'm
seeing this only in X, while he sees it on his console, yet I think
the two problems are related. I've also reworked the patch slightly
to conform to the coding standards of adjacent code.
It is unclear to me if this merely masks the maddening bug that I have
seen, or if this is a real fix. I typically see the problem when I'm
typing fast in emacs and using lots of motion keys (meta and control).
In either case, my workstation at work again is finally useful with
