use this ioctl to obtain the list of HCI nodes. User-space application
is expected to preallocate 'ng_btsocket_hci_raw_node_list_names' structure
and set limit in 'num_nodes' field. The 'nodes' field should be allocated
as well and it should have space for at least 'num_nodes' elements.
The SIOC_HCI_RAW_NODE_LIST_NAMES should be issued on bound raw HCI socket.
It does not really really matter what HCI name the socket is bound to, as
long as it is not empty.

It is no longer needed, because "mount -t reiserfs" calls nmount(2)
directly to mount a ReiserFS file system without the use of
this external mount program.

still should return BUS_PROBE_LOW_PRIORITY instead of BUS_PROBE_DEFAULT
in order to give pcn(4) a chance to attach in case it probes after le(4).
- Rearrange the code related to RX interrupt handling so that ownership of
RX descriptors is immediately returned to the NIC after we have copied
the data of the hardware, allowing the NIC to already reuse the descriptor
while we are processing the data in ifp->if_input(). This results in a
small but measurable increase in RX throughput.
As a side-effect, this moves the workaround for the LANCE revision C bug
to am7900.c (still off by default as I doubt we will actually encounter
such an old chip in a machine running FreeBSD) and the workaround for the
bug in the VMware PCnet-PCI emulation to am79000.c, which is now also
only compiled on i386 (resulting in a small increase in RX throughput on
the other platforms).
- Change the RX interrupt handlers so that the descriptor error bits are
only check once in case there was no error instead of twice (inspired
by the NetBSD pcn(4), which additionally predicts the error branch as
false).
- Fix the debugging output of the RX and TX interrupt handlers; while
looping through the descriptors print info about the currently processed
one instead of always the previously last used one; remove pointless
printing of info about the RX descriptor bits after their values were
reset.
- Create the DMA tags used to allocate the memory for the init block,
descriptors and packet buffers with the alignment the respective NIC
actually requires rather than using PAGE_SIZE unconditionally. This might
as well fix the alignment of the memory as it seems we do not inherit
the alignment constraint from the parent DMA tag.
- For the PCI variants double the number of RX descriptors and buffers
from 8 to 16 as this minimizes the number of RX overflows im seeing with
one NIC-mainboard combination. Nevertheless move reporting of overflows
under debugging as they seem unavoidable with some crappy hardware.
- Set the software style of the PCI variants to ILACC rather than PCnet-PCI
as the former is was am79000.c actually implements. Should not make a
difference for this driver though.
- Fix the driver name part in the MODULE_DEPEND of the PCI front-end for
ether.
- Use different device descriptions for PCnet-Home and PCnet-PCI.
- Fix some 0/NULL confusion in lance_get().
- Use bus_addr_t for sc_addr and bus_size_t for sc_memsize as these are
more appropriate than u_long for these.
- Remove the unused LE_DRIVER_NAME macro.
- Add a comment describing why we are taking the LE_HTOLE* etc approach
instead of using byteorder(9) functions directly.
- Improve some comments and fix some wording.

* Document SF_SNAPSHOT and note that it is maintained by the

gateways which are unreachable except through the default router. For
example, assuming there is a default route configured, and inserting
a route
"route add 64.102.54.0/24 60.80.1.1"
is currently allowed even when 60.80.1.1 is only reachable through
the default route. However, an error is thrown when this route is
utilized, say,
"ping 64.102.54.1" will return an error
This type of route insertion should be disallowed becasue:
1) Let's say that somehow our code allowed this packet to flow to
the default router, and the default router knows the next hop is
60.80.1.1, then the question is why bother inserting this route in
the 1st place, just simply use the default route.
2) Since we're not talking about source routing here, the default
router could very well choose a different path than using 60.80.1.1
for the next hop, again it defeats the purpose of adding this route.

Current code does not report link loss correctly - when link goes down,
mii_phy_tick() will notice that with up to mii_anegticks delay.
If link goes up during this delay then link flapping will be unnoticed
by driver.
2) mii_phy_add_media(): initialize sc->mii_anegticks for 10/100 media
3) Use MII_ANEGTICKS/MII_ANEGTICKS_GIGE defines instead of hardcoded values.
