de01564f85 Don't bother clearing maps for static DMA allocations to NULL. Instead,
leave them as purely opaque values that are only set by bus_dmamem_alloc().

43b6b3d843 Fix one race and one fence post error. When the TX buffer was
completely full, we'd not complete any of the mbufs due to the fence
post error (this creates a large leak). When this is fixed, we still
leak, but at a much smaller rate due to a race between ateintr and
atestart_locked as well as an asymmetry where atestart_locked is
called from elsewhere.  Ensure that we free in-flight packets that
have completed there as well. Also remove needless check for NULL on
mb, checked earlier in the loop and simplify a redundant if.

37a43650ed Functions m_getm2() and m_get2() have different order of arguments,
and that can drive someone crazy. While m_get2() is young and not
documented yet, change its order of arguments to match m_getm2().

Sorry for churn, but better now than later.

ac757f20dd Converted the remainder of the NIC drivers to use the mii_attach()
introduced in r213878 instead of mii_phy_probe(). Unlike r213893 these
are only straight forward conversions though.

213eac1f2c Add new tunable 'net.link.ifqmaxlen' to set default send interface
queue length. The default value for this parameter is 50, which is
quite low for many of today's uses and the only way to modify this
parameter right now is to edit if_var.h file. Also add read-only
sysctl with the same name, so that it's possible to retrieve the
current value.

be5740a255 Use if_maddr_rlock()/if_maddr_runlock() rather than IF_ADDR_LOCK()/
IF_ADDR_UNLOCK() across network device drivers when accessing the
per-interface multicast address list, if_multiaddrs.  This will
allow us to change the locking strategy without affecting our driver
programming interface or binary interface.

For two wireless drivers, remove unnecessary locking, since they
don't actually access the multicast address list.
