Fix the CTL OOA queue dumping code so that it does not hold a mutex
while doing a copyout. That can cause a panic, because copyout
can trigger VM faults, and we can't handle VM faults while holding
a mutex.
The solution here is to malloc a separate buffer to hold the OOA
queue entries, so that we don't risk a VM fault while filling up
the buffer and we don't have to drop the lock. The other solution
would be to wire the user's memory while filling their buffer with
copyout, but that would have been a little more complex.

When the kernel is running in a virtual machine, it cannot rely upon the
processor family to determine if the workaround for AMD Family 10h Erratum

Therefore, when the kernel is running in a virtual machine, instead of

For NFS mounts using rsize,wsize=65536 over TSO enabled
network interfaces limited to 32 transmit segments, there
are two known issues.
The more serious one is that for an I/O of slightly less than 64K,
the net device driver prepends an ethernet header, resulting in a
TSO segment slightly larger than 64K. Since m_defrag() copies this
into 33 mbuf clusters, the transmit fails with EFBIG.
A tester indicated observing a similar failure using iSCSI.
The second less critical problem is that the network
device driver must copy the mbuf chain via m_defrag()
(m_collapse() is not sufficient), resulting in measurable overhead.
This patch reduces the default size of if_hw_tsomax
slightly, so that the first issue is avoided.
Fixing the second issue will require a way for the
network device driver to inform tcp_output() that it
