gigabit ethernet and JMC260 fast ethernet controllers. ATM jme(4)
supports all hardware features except RSS and multiple Tx/Rx queue.
In these days most ethernet controller vendors take a ply of
concealing hardware detailes from open source developers. As
contrasted with these vendors JMicron provided all necessary
information needed to write a stable driver during driver writing
and answered many questions I had. They even helped fixing driver
bugs with protocol analyzer. Many thanks to JMicron for their
support of FreeBSD.

Anyway, in the edge case the flushing happens and the while is no more
executed, nfs_flush() (and nfs4_flush()) can return with a wrong
err value of ENOLCK.
Bring it back to 0, as we expect to have for that case.

Most of I4B has been disconnected from the build
since July 2007 in HEAD/RELENG_7.
This is what was removed:
- configuration in /etc/isdn
- examples

- kernel configuration
- sys/i4b (drivers, layers, include files)
- user space tools
- i4b support from ppp
- further documentation

context, where the iwn mutex is being held, and
iwn_start assumes that we do not have that mutex held.
Resolve this issue with what we do for other NICs by
splitting the iwn_start procedure into two parts,
iwn_start() do the locking, and iwn_start_locked()
assumes that the mutex is being held. This resolves
panic when WITNESS is enabled.

months in HEAD/RELENG_7. Specifics:
- netatm include files
- netatm command line management tools

- ATM parts in rescue and sysinstall
- sample configuration files and documents
- kernel support as a module or in NOTES
- netgraph wrapper nodes for netatm
- ctags data for netatm.
- netatm-specific device drivers.

release barrier.

Moreover, neither Linux nor Solaris impose this requirement. This

- Use proper synhronization primitives to protect the internal fdesc node cache
used in fdescfs.
- Properly initialize and uninitalize hash.
- Remove unused functions.
Since fdescfs might recurse on itself, adding proper locking to it needed some
tricky workarounds in some parts to make it work. For instance, a descriptor in
fdescfs could refer to an open descriptor to itself, thus forcing the thread to
recurse on vnode locks. Because of this, other race conditions also had to be
fixed.
