m_pkthdr.ether_vlan. The presence of the M_VLANTAG flag on the mbuf
signifies the presence and validity of its content.
Drivers that support hardware VLAN tag stripping fill in the received
VLAN tag (containing both vlan and priority information) into the
ether_vtag mbuf packet header field:
m->m_pkthdr.ether_vtag = vlan_id; /* ntohs()? */
m->m_flags |= M_VLANTAG;
to mark the packet m with the specified VLAN tag.
On output the driver should check the mbuf for the M_VLANTAG flag to
see if a VLAN tag is present and valid:
if (m->m_flags & M_VLANTAG) {
... = m->m_pkthdr.ether_vtag; /* htons()? */
... pass tag to hardware ...
}
VLAN tags are stored in host byte order. Byte swapping may be necessary.
(Note: This driver conversion was mechanic and did not add or remove any
byte swapping in the drivers.)
Remove zone_mtag_vlan UMA zone and MTAG_VLAN definition. No more tag
memory allocation have to be done.

- Added support for multicast filtering, now that the firmware
supports it. Note that this is not yet tested, as multicast
seems to panic -current (even w/o mxge loaded)
- Added workaround to cope with different irq data struct size on
pre-multicast firmware which can found running on nics.
- Added Intel E5000 PCIe chipsets to list providing aligned completions.
- Replaced various magic constants with #defines, now that they are
defined in the firmware headers.

- Fixed transmit routine to ensure it doesn't read past the end
of an mbuf when parsing headers.
- Corrected handling of odd length segments. Setting MXGEFW_FLAGS_ALIGN_ODD
is required only when offloading the checksum of that frame.

in syscons. This replaces a simple access semaphore that was assumed to be
protected by Giant but often was not. If two threads that were otherwise
SMP-safe called printf at the same time, there was a high likelyhood that
the semaphore would get corrupted and result in a permanently frozen video
console. This is similar to what is already done in the serial console
drivers.
Instead, we want busses to explicitly specify an add_child routine if they
want to support identify routines, but by default disallow having outside
drivers add devices.
- Give smbus(4) an explicit bus_add_child() method.

- Change smbus_callback() to pass a void * rather than caddr_t.
- Change smbus_bread() to pass a pointer to the count and have it be an
in/out parameter. The input is the size of the buffer (same as before),
but on return it will contain the actual amount of data read back from
the bus. Note that this value may be larger than the input value. It
is up to the caller to treat this as an error if desired.
- Change the SMB_BREAD ioctl to write out the updated struct smbcmd which
will contain the actual number of bytes read in the 'count' field. To
preserve the previous ABI, the old ioctl value is mapped to SMB_OLD_BREAD
which doesn't copy the updated smbcmd back out to userland. I doubt anyone
actually used the old BREAD anyway as it was rediculous to do a bulk-read
but not tell the using program how much data was actually read.
- Make the smbus driver and devclass public in the smbus module and
push all the DRIVER_MODULE()'s for attaching the smbus driver to
various foosmb drivers out into the foosmb modules. This makes all
the foosmb logic centralized and allows new foosmb modules to be
self-contained w/o having to hack smbus.c everytime a new smbus driver
is added.
- Add a new SMB_EINVAL error bit and use it in place of EINVAL to return
an error for bad arguments (such as invalid counts for bread and bwrite).
- Map SMB bus error bits to EIO in smbus_error().
- Make the smbus driver call bus_generic_probe() and require child drivers
such as smb(4) to create device_t's via identify routines. Previously,
smbus just created one anonymous device during attach, and if you had
multiple drivers that could attach it was just random chance as to which
driver got to probe for the sole device_t first.
- Add a mutex to the smbus(4) softc and use it in place of dummy splhigh()
to protect the 'owner' field and perform necessary synchronization for
smbus_request_bus() and smbus_release_bus().
- Change the bread() and bwrite() methods of alpm(4), amdpm(4), and
viapm(4) to only perform a single transaction and not try to use a
loop of multiple transactions for a large request. The framing and
commands to use for a large transaction depend on the upper-layer
protocol (such as SSIF for IPMI over SMBus) from what I can tell, and the
smb(4) driver never allowed bulk read/writes of more than 32-bytes
anyway. The other smb drivers only performed single transactions.
- Fix buffer overflows in the bread() methods of ichsmb(4), alpm(4),
amdpm(4), amdsmb(4), intpm(4), and nfsmb(4).
- Use SMB_xxx errors in viapm(4).
- Destroy ichsmb(4)'s mutex after bus_generic_detach() to avoid problems
from child devices making smb upcalls that would use the mutex during
their detach methods.

to it. Try to co-operate with the IPMI/ASF firmware accessing the PHY.
One we get link we don't mess with the PHY. If we do then over time
the NIC will go off line. It would be nice if we could tell if IPMI
was enabled on the chip but I can't figure out a reliable way to do
that. The scheme I tried worked on a Dell PE850 but not on an HP machine.
So we assume any NIC that has ASF capability needs to deal with it.
The code was inspired by the support in Linux from kernel.org and Broadcom.
Broadcom did give me some info. but it is rather limited and is mostly
just what is in the Linux driver. Thanks to the numerous people that
helped debug the many prior versions and that I didn't break other
bge(4) HW.

Ever since rev 1.68 re(4) checks the validity of link in re_start.
But rlphy(4) got a garbled data due to a different bit layout used on
8139C+ and it couldn't report correct link state. To fix it, ignore
BMCR_LOOP and BMCR_ISO bits which have different meanings on 8139C+.
I think this also make dhclient(8) work on 8139C+.

We establish a SYSINIT hook to call this handler. The current usage for it
is to add scsi target resources *after* all enables are done. There seems
to be some dependencies between different halves of a dual-port with respect
to target mode.
Put in more meaningful event messages for some events- in particular
QUEUE FULL events so we can see what the queue depth was when the
IOC sent us this message.

AEN. This makes the boot messages cleaner. I now know how this

I added the time stamp/locale/class so people can parse messages better.
Create a sysctl so that we can set the locale/class level.
