modifications merged. I had initially expected that people would
put any local changes into /boot/loader.conf, but it turns out that
editing /boot/device.hints is something many people do.

shared libraries.
This fixes a problem which resulted in 6.x->7.x upgrades having the
/usr/lib/libpthread.so -> libthr.so symlink missing; what happened was
that the old libpthread.so symlink pointed to /lib/libpthread.so.2 --
which matched the "/lib/*\.so\.[0-9]+" regex -- but the new symlink
didn't, so FreeBSD Update got confused and deleted the symlink as part
of its "remove old shared libraries" step.
To recreate the symlink (which I understand is necessary for ports like
KDE to build) on a 7.x system which FreeBSD Update upgraded from 6.x:
# ln -s libthr.so /usr/lib/libpthread.so

Removed dead code that assumed that M_TRYWAIT can return NULL; it's not true
since the advent of MBUMA.

There are ongoing disputes as to whether we want to switch to directly using
UMA flags M_WAITOK/M_NOWAIT for mbuf(9) allocation.
bpf_canfreebuf() in order to avoid potentially calling a non-inlinable
but trivial function in zero-copy buffer mode for every packet
received when we couldn't free the buffer anyway.

of pptpgre and ksocket nodes for all calls between two peers. This patch
modifies node's API by adding new "session_%04x" hook names support, while
keeping backward compatibility.
Together with appropriate user-level support (by latest mpd5) it gives
huge performance benefits for case of multiple active calls between
two peers because of avoiding data duplication and extra socket processing.
On my benchmarks I have got more then 10 times speedup for the 200
simultaneous PPTP calls between two peers.
In conclusion, it allows now to build effective "clients <=> PAC <=> PNS"
setups.
o sort mbuf flags together and extend values to 32 bits
o write M_COPYFLAGS in terms of M_PROTOFLAGS
o move M_COPYFLAGS and M_PROTOFLAGS up to be together with flag defs

- Take advantage of m_collapse(9).
- Sync with other NIC drivers and prepend a TX mbuf if the first attempt
to load it fails with an error other than EFBIG and stop trying instead
of freeing it and keeping on trying to enqueue more mbufs. Also ensure
the driver queue isn't empty before trying to enqueue mbufs in order to
reduce locking operations.
- In xl_ifmedia_upd() add a missing XL_UNLOCK(). [1]
- Const'ify the xl_devs array.

- Correct the maxsize parameter when creating the mbufs busdma tag to
reflect the actual requirement of dc(4).
- Move the KASSERT in dc_newbuf() to the right spot.
- Also convert the TX side to take advantage of bus_dmamap_load_mbuf_sg(9).
- Move the comment regarding dc_start_locked() to the right spot.
