- Linux ioctl support, with the other Linux changes MegaCli
will run if you mount linprocfs & linsysfs then set
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.

full, kick the binary blob to force it to complete any pending tx
completions.
- In the watchdog routine, only reset the chip if the blob doesn't complete
any pending tx completions rather than requiring it to complete all of
the pending tx completions.

lnc(4) on PC98 and i386. The ISA front-end supports the same non-PNP
network cards as lnc(4) did and additionally a couple of PNP ones.
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.
- Remove the descriptions of le(4), which where converted from lnc(4),
from sys/i386/conf/NOTES and sys/pc98/conf/NOTES as there's a common
one in sys/conf/NOTES.
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.

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.

If the embedded controller exists before the sysresource devices, for
example, it will be attached first. Instead, let the normal device
order function work as we first desired. [1]
There still remained a problem where we couldn't allocate resources in
acpi0 that were passed up by the sysresource pseudo-devices. These
devices had to probe/attach first to give their resources to acpi, then
acpi would allocate them before probing/attaching other devices. To
work around this, we attach them from acpi_sysres_alloc(). A better
approach would be to implement multi-pass probe/attach in newbus but
that's a much bigger task.

- Fix bfe_encap so that it will pass the address of the mbuf back up to its
caller if/when it modifies it, as it does when doing a m_defrag on a mbuf chain.
- Make sure to unload the dmamap for ALL fragments of a packet, not just the first
- Use BUS_DMA_NOWAIT for all bus_dmamap_load calls so that the allocation of the
map is not delayed - this driver is not set up to handle such delays.
- Reduce the number of RX and TX buffers bfe uses so that it does not use more
bounce buffers than busdma is willing to allow it to use
With these changes, the driver now works properly for a user with a 2GB system,
and it also works on my system when the acceptable address range is lowered to 128MB.
Previously, both of these setups would act up after a few minutes of activity.

I tested this with 2 amr controllers in one box. It seems to work
okay with them.
o Properly use rman(9) to manage resources. This eliminates the
need to puc-specific hacks to rman. It also allows devinfo(8)
to be used to find out the specific assignment of resources to
serial/parallel ports.
o Compress the PCI device "database" by optimizing for the common
case and to use a procedural interface to handle the exceptions.
The procedural interface also generalizes the need to setup the
hardware (program chipsets, program clock frequencies).
o Eliminate the need for PUC_FASTINTR. Serdev devices are fast by
default and non-serdev devices are handled by the bus.
o Use the serdev I/F to collect interrupt status and to handle
interrupts across ports in priority order.
o Sync the PCI device configuration to include devices found in
NetBSD and not yet merged to FreeBSD.
o Add support for Quatech 2, 4 and 8 port UARTs.
o Add support for a couple dozen Timedia serial cards as found
in Linux.
