This avoids creating windows where a device file is accessible but the
device-specific field is not set.
Now that vmmdev_mtx is a sleepable lock, avoid dropping it while
creating devices files. This makes it easier to handle races and
simplifies some code; for example, the VSC_LINKED flag is no longer
needed.

Rather than performing privilege checks after a specific VM's device
file is opened, do it once at the time the device file is opened. This
means that one can continue to access a VM via its device fd after
attaching to a jail which does not have vmm enabled, but this seems like
a reasonable semantic to have anyway.

The sole caller of this function already holds a pointer to the VM's

pass the softc pointer directly. This function is only called from an

The driver sets the Maximum Transmission Unit (MTU) at the Virtual Station
Interface (VSI) level, which leads to a discrepancy in the GLPRT_ROC counter's
ability to accurately tally oversized packets, as this counter operates at the
physical port level. To rectify this issue, it is necessary to take an
additional register (GL_RXERR1) into account to obtain the correct count of
oversized packets.

This file contains the vmm device file implementation. Most of this
code is not machine-dependent and so shouldn't be duplicated this way.
Move most of it into a generic dev/vmm/vmm_dev.c. This will make it
easier to introduce a cdev-based interface for VM creation, which in
turn makes it possible to implement support for running bhyve as an
unprivileged user.
Machine-dependent ioctls continue to be handled in machine-dependent
code. To make the split a bit easier to handle, introduce a pair of
tables which define MI and MD ioctls. Each table entry can set flags
which determine which locks need to be held in order to execute the
handler. vmmdev_ioctl() now looks up the ioctl in one of the tables,
acquires locks and either handles the ioctl directly or calls
vmmdev_machdep_ioctl() to handle it.
No functional change intended. There is a lot of churn in this change
but the underlying logic in the ioctl handlers is the same. For now,
vmm_dev.h is still mostly separate, even though some parts could be
merged in principle. This would involve changing include paths for
userspace, though.
