ceiling as a fraction of the kernel map's size rather than an absolute

changes to the kernel map's size.
datagram-only protocols, such as UDP. This version removes use of
sblock(), which is not required due to an inability to interlace data
improperly with datagrams, as well as avoiding some of the larger loops
and state management that don't apply on datagram sockets.
This is experimental code, so hook it up only for UDPv4 for testing; if
there are problems we may need to revise it or turn it off by default,
but it offers *significant* performance improvements for threaded UDP
applications such as BIND9, nsd, and memcached using UDP.

ATM Tx/Rx checksum offload is supported but TSO and jumbo frame is
not yet supported. Because these newer controllers use different
descriptor formats, a flag RL_FLAG_DESCV2 flag was introduced to
handle that case in Tx/Rx handler. Also newer controllers seems to
require to not touch 'enable Tx/Rx bit' in RL_CPLUS_CMD register
so don't blindly try to set that bits.
Note, it seems that there is still power-saving related issue where
driver fails to attach PHY. Rebooting seems to fix that issue but
number of required reboots varys.
Many thanks to users that helped during developement. I really
appreciate their patient and test/feedbacks.
a dedicated flag that represents controller capabilities/events.
This will simplify many part of code that requires different
workaround for each controller revisions and will enhance
readability.
While I'm here move PHY wakeup code up before mii_phy_probe() which
seems to help to wake PHY in some cases.
RL_TXCFG register to identify a device in device probe. Reflect the
fact by modifing device description with general ethernet
controller family.
Note, rl_basetype in struct rl_type is not used and the more
detailed information is provided with rl_hwrev structure.

Previously we reused the space in the request buffer after the request
header to hold config pages during a transaction. This does not work when
reading large pages however. Also, we were already malloc'ing a buffer to
do a copyin/copyout w/o holding locks that was then copied into/out of the
request buffer. Instead, go ahead and use bus dma to alloc a buffer for
each config page request (and RAID actions that have an associated
ActionSGE). This results in fewer data copies and allows for larger sized
requests. For now the maximum size of a request is arbitrarily limited to
16 MB.

bridging implementations and makes bridges more predictable after reboots for

In the MPSAFE TTY branch, I noticed PTY's to be leaked, because
dhclient's privileged process was run inside the session of, say, the
login shell. Make sure we call setsid() here.

rather than write locking: while we need to maintain a valid reference
to the inpcb and fix its state, no protocol layer state is modified
during an IPv4 UDP receive -- there are only changes at the socket
layer, which is separately protected by socket locking.
While parallel concurrent receive on a single UDP socket is currently
relatively unusual, introducing read locking in the transmit path,
allowing concurrent receive and transmit, will significantly improve
performance for loads such as BIND, memcached, etc.
