of the struct plex, which tore apart the mutex linked lists when the
plex table was expanded. Now we maintain a pool of mutexes (currently
32) to be shared by all plexes. This is still a lot better than the
splhigh() method used in other architectures.
Add and clarify comments.

Correct some inaccurate and badly formatted comments.
config_subdisk: If our drive is down, ensure that the subdisk is
crashed. Previously it was possible for the subdisk
to be up when the drive was down.
Change the way the plex lock mutexes work. Previously they were part
of the struct plex, which tore apart the mutex linked lists when the
plex table was expanded. Now we maintain a pool of mutexes (currently

on if_fxp cards. When flow control is enabled, if the operating system
doesn't acknowledge the packet buffer filling, the card will begin to
generate ethernet quench packets, but appears to get into a feedback
loop of some sort, hosing local switches. This is a temporary workaround
for 5.1: the ability to configure flow control should probably be
exposed by some or another management interface on ethernet link layer
devices.

all of the Optio series have the same problems. It might be a better
approach eventually to add wildcard support to USB quirks.

- Fix compilation without GEM_DEBUG.
- Do not #define GEM_DEBUG by default; it adds overhead (due to bzero()ing
RX space) and is not needed any more, since the driver is quite stable
now.
- Fix watchdog timeouts when failing to load TX packets.
- Do not forcibly limit the number of descriptors used for a packet to
GEM_NTXSEGS, by passing this number to bus_dma_tag_create(). There is
no requirement for a limit any lower than the total number of
available descriptors, and the present limit caused network problems
due to mbuf chains requiring more descriptors.
GEM_NTXSEGS is still used to estimate the interrupt window size, for
which we just need an estimate.
