kernel lock in the rx and tx path anymore.
While there seems to be a small decrease in forwarding performance with our
default network stack settings, Performance whiel receiving manymore packets
than we can handle is better. And this change opens the road for future
improvements in the network stack.

the possible number of slots a packet can use on the tx ring.
to make it easier to reserve and account for space on the ring,
half the number of dma descriptors on those chips so the number of
slots can stay the same.

in inteldrm(4).
The Intel integrated graphics device has a major design flaw where it needs
legacy VGA io access to disable VGA mode completely. This only works if
legacy VGA io routing is setup such that it actually reaches the IGD. This
typically isn't the case if the primary VGA device is a discrete graphics
device. To make sure we don't whack that device we have to temporarily
route legacy VGA io access to the IGD.
Fixes the "black screen" issue reported by Timo Myrra and others.

7Y250M0, refuse to do DMA unless the transfer mode has been set. This causes
reads (and presumably writes) to time out.
Unlike the wdc code, this only sets the UltraDMA transfer mode. If we ever
want to support ancient PATA drivers through the atascsi layer, we probably
need to set the PIO and/or MWDMA transfer modes as well.

2. Replace a continue statement in an inner loop with goto loop_end
This fixes a simple logical bug found with Coccinelle.

positions when deciding how much work to do, and to adjust rl_tx_free with
atomic operations; split the flag that indicates whether we're using
timer based interrupts or not out into a separate field so it can be
changed from interrupt context without needing a lock; take the kernel
lock when calling re_init and re_start from interrupt context; add an
interrupt barrier in re_stop; and finally mark the interrupt handler
as mpsafe.

becomes much more reliably if we pay attention to the IBF and OBF flags.
This removes the need for excessive delays and retries, making operations
complete in microseconds instead of seconds.
This diff also removes flushing the read buffer after a read operations. This
doesn't seem to be necessary, but we might need to put that back if the
length of a reply changes for some keys.

This patch adds a new driver for use of virtio-console devices as
ttys. It's still in an early state and not compiled by default, yet.
Currently it is only wired into amd64. i386 is still missing.

error condition in an inner loop. Found with Coccinelle.

Mask the event port during xen_intr_establish, but don't set the
masked flag in the intsrc. By providing mask and unmask routines
we allow the device to decide when to perform these actions. The
port will still be unmasked during xen_intr_enable. This allows
netfront to fulfil the intr_barrier pattern requirements fairly
easily and at the same time should be sufficient for diskfront
that doesn't need to fiddle with interrupt masking.
