- Add a count of exiting threads, p_exitthreads, to struct proc.
- Increment p_exithreads when we set the deadthread in thread_exit().
- When we thread_stash() a deadthread use an atomic to drop the count.
- Spin until the p_exithreads count reaches 0 in thread_wait().
- Lock the last exiting thread momentarily to be certain that it has
exited cpu_throw().
- Restructure thread_wait(). It does not need a loop as there will only
ever be one thread.

MCLBYTES for the segment size but it used too many Tx descriptors in
TSO case.
While I'm here adjust maximum size of the sum of all segment lengths
in a given DMA mapping to 65535, the maximum size, in bytes, of a IP
packet.
o s/printf/device_printf/g
o Nuke OpenBSDism.
o Nuke NetBSD/OpenBSD specific DMA sync operations.(we don't have a way
to sync a single descriptor within a DMA map.)
o Remove recursive mutex.
o bus_dma(9) clean up.
o 40bit DMA address support.
o Add protection for Rx map load failure.
o Fix a long standing bug for watchdog timeout. [1]
o Add additional protections, missing Tx completion interrupt, losing
start Tx command, for watchdog timeout.
o Switch to taskqueue(9) API to handle interrupts.
o Use our own timer for watchdog instead of if_watchdog/if_timer
interface.
o Advertise VLAN header length/capability correctly to upper layer.
o Remove excessive kernel stack consumption in nfe_encap().
o Handle highly fragmented mbuf chains correctly.
o Enable etherenet address reprogramming with ifconfig(8).
o Add ALTQ/TSO, MSI/MSIX support.
o Increased Rx ring to 256 descriptors from 128.
o Align Tx/Rx descriptor ring on sizeof(struct nfe_desc64) boundary.
o Remove alignment restrictions on Tx/Rx buffers.
o Rewritten jumbo frame support code.
o Add support for hardware assistend VLAN tag insertion/stripping.
o Add support for Tx/Rx flow control based on patches from Peer Chen. [2]
o Add a routine that detects whether ethernet address swap routines is
required. [3]
o Add a workaround that take MAC/PHY out of power down mode.
o Add suspend/resume support.
o style(9) and code clean up.
Special thanks to Shigeaki Tagashira, the original porter of nfe(4),
who submitted lots of patches, performed uncountable number of
regression tests and maintained nfe(4) for a long time. Without his
enthusiastic help and support I could never have completed this
overhauling task.
The only weak point of nfe(4) compared to nve(4) is instability of
manual half-duplex media selection on certain hardwares(auto sensing
media type should work for all cases, though). This was a long
standing bug of nfe(4) and I still have no idea why it doesn't work
on some hardwares.

some cases, move to priv_check() if it was an operation on a thread and
no other flags were present.
Eliminate caller-side jail exception checking (also now-unused); jail
privilege exception code now goes solely in kern_jail.c.
We can't yet eliminate suser() due to some cases in the KAME code where
a privilege check is performed and then used in many different deferred
paths. Do, however, move those prototypes to priv.h.

id used by sysinstall when enabling anonymous FTP.
Change the default group used by sysinstall for setting up anonymous FTP
from operator to ftp; there is no reason to use operator and there are
potential security issues when doing so.

a warning, return 1 instead of 0 to indicate that we didn't print
anything, so that top-level callers don't print a spurious newline.
This is mainly to fix output formatting when stderr is redirected. It
also helps in some cases when stderr is interleaved with stdout,
depending on the details of the interleaving (this program has the
usual null explicit support for syncing stderr with stdout).
Return 1 instead of -1 after printing the "malloc failed" warning, since
the return value is boolean.
- Use a seperate taskqueue+thread for reset tasks since iwi_ops will
block.
- Return from iwi_ops if the interface has been downed
