sysctl compat.linux.osrelease=2.6.12 or similar. This works
on i386. It should work on amd64 but not well tested yet.
StoreLib may or may not work. Remember to kldload mfi_linux.
- Add in AEN (Async Event Notification) support so we can
get messages from the firmware when something happens.
Not all messages are in defined in event detail. Use
event_log to try to figure out what happened.
- Try to implement something like SIGIO for StoreLib. Since
mrmonitor doesn't work right I can't fully test it. StoreLib
works best with the rh9 base. In theory mrmonitor isn't
needed due to native driver support of AEN :-)
Now we can configure and monitor the RAID better.

Note that whilst these members are not used by the ip_output()
path, we are passing an instance of struct ip_moptions here
which is declared on the stack (which could be considered a
bad thing).
ip_output() does not consume struct ip_moptions, but in case it
does in future, declare an in_multi vector on the stack too to
behave more like ip_findmoptions() does.

Like lnc(4), the C-bus front-end of le(4) only supports C-NET(98)S
and is untested due to lack of such hardware, but given that's it's
based on the respective lnc(4) and not too different from the ISA
front-end it should be highly likely to work.

The bug also exists in NetBSD, OpenBSD and various other independed

- We cannot decide which hash function to use for HMAC based on the key
length, because any HMAC function can use any key length.
To fix it split CRYPTO_SHA2_HMAC into three algorithm:
CRYPTO_SHA2_256_HMAC, CRYPTO_SHA2_384_HMAC and CRYPTO_SHA2_512_HMAC.
Those names are consistent with OpenBSD's naming.
- Remove authsize field from auth_hash structure.
- Allow consumer to define size of hash he wants to receive.
This allows to use HMAC not only for IPsec, where 96 bits MAC is requested.
The size of requested MAC is defined at newsession time in the cri_mlen
field - when 0, entire MAC will be returned.
- Add swcr_authprepare() function which prepares authentication key.
- Allow to provide key for every authentication operation, not only at
newsession time by honoring CRD_F_KEY_EXPLICIT flag.
- Make giving key at newsession time optional - don't try to operate on it
if its NULL.
- Extend COPYBACK()/COPYDATA() macros to handle CRYPTO_BUF_CONTIG buffer
type as well.
- Accept CRYPTO_BUF_IOV buffer type in swcr_authcompute() as we have
cuio_apply() now.
- 16 bits for key length (SW_klen) is more than enough.

crypto_invoke(). This allows to serve multiple crypto requests in
parallel and not bached requests are served lock-less.
Drivers should not depend on the queue lock beeing held around
crypto_invoke() and if they do, that's an error in the driver - it
should do its own synchronization.
- Don't forget to wakeup the crypto thread when new requests is
queued and only if both symmetric and asymmetric queues are empty.
- Symmetric requests use sessions and there is no way driver can
disappear when there is an active session, so we don't need to check
this, but assert this. This is also safe to not use the driver lock
in this case.
- Assymetric requests don't use sessions, so don't check the driver
in crypto_kinvoke().
- Protect assymetric operation with the driver lock, because if there
is no symmetric session, driver can disappear.
- Don't send assymetric request to the driver if it is marked as
blocked.
- Add an XXX comment, because I don't think migration to another driver
is safe when there are pending requests using freed session.
- Remove 'hint' argument from crypto_kinvoke(), as it serves no purpose.
- Don't hold the driver lock around kprocess method call, instead use
cc_koperations to track number of in-progress requests.
- Cleanup register/unregister code a bit.
- Other small simplifications and cleanups.

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.

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.

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.
