build_mlx_header() was using sqp->ud_header.grh_present before it was
initialized by mthca_read_ah(). Furthermore, header->grh_present is
set by ib_ud_header_init, so there's no need to set it again in
mthca_read_ah().

The current handling of multicast groups in IPoIB ends up never
freeing send-only multicast groups. It turns out the logic was much
more complicated than it needed to be; we can fix this bug and
completely kill ipoib_mcast_dev_down() at the same time.

At least some versions of the via-velocity hardware only support
checksumming IPv4 frames in hardware. However, the driver is currently
setting the NETIF_F_HW_CSUM flag, which indicates support for more than
just IPv4. This results in errors when trying to use IPv6 over
via-velocity hardware.

I believe I see the race Michael refers to (tlb_choose_channel
may set head, which tlb_init_slave clears), although I was not able to
reproduce it. I have updated his patch for the current netdev-2.6.git
tree and added a version update. His original comment follows:
Our systems have been crashing during testing of PCI HotPlug
support in the various networking components. We've faulted in
the bonding driver due to a bug in bond_alb.c:tlb_clear_slave()
In that routine, the last modification to the TLB hash table is
made without protection of the lock, allowing a race that can lead
tlb_choose_channel() to select an invalid table element.

This patch allows the Atmel driver to work correctly with wpa_supplicant
and other programs that require some conformance with WEXT-18. It
should not affect current behavior of the driver. The patch does four
things:
1) Implements SIOCSIWENCODEEXT, SIOCGIWENCODEEXT, SIOCSIWAUTH, and
SIOCGIWAUTH calls for unencrypted and WEP operation
2) Accepts zero-filled addresses for SIOCSIWAP, which are legal and
should turn off any previous forced WAP address
3) Sends association and de-association events to userspace at most of
the appropriate times
4) Fixes erroneous order of CIPHER_SUITE_WEP_* arguments in one location
which are actually unused anyway

We have identified two related bugs in the e100 driver.
Both bugs are related to manipulation of the MDI control register.
The first problem is that the Ready bit is being ignored when writing to
the Control register; we noticed this because the Linux bonding driver
would occasionally come to the spurious conclusion that the link was down
when querying Link State. It turned out that by failing to wait for a
previous command to complete it was selecting what was essentially a random
register in the MDI register set. When we added code that waits for the
Ready bit (as shown in the patch file below) all such problems ceased.
The second problem is that, although access to the MDI registers involves
multiple steps which must not be intermixed, nothing was defending against
two or more threads attempting simultaneous access. The most obvious
situation where such interference could occur involves the watchdog versus
ioctl paths, but there are probably others, so we recommend the locking
shown in our patch file.

While trying to get SUSE's SLES9 working on system with more than 4GB we've
noticed that SCSI layer happilly passes addresses over 4GB to the buslogic
driver, which is quite a big problem as buslogic can generate only 32bit
busmastering cycles.
Fortunately in the current kernels this problem does not exist anymore as
SCSI layer now assumes 4GB capable device by default, but it is still good
idea to pass correct device structure to the SCSI layer. If nothing else,
/sys/block/sda/device now points to
/sys/devices/pci0000:00/0000:00:10.0/host0/... instead of
/sys/devices/platform/host0/... like it did in the past.
Change does nothing for ISA based BusLogic adapters, they'll still end
under platform (and they are probably broken for long time as I do not see
anything forcing ISA 16MB limit for them).

There's a problem with the REQ_BLOCK_PC handling as well (bad ->data_len
handling) where it could actually complete a request ahead of time. I
suggest we just back this out for now, I will resubmit it later when I'm
fully confident in it.

we always set ->SCp.ptr to physical address of buffer; for DMA that's
just what we need, but we end up using it as virtual address in PIO
case of esp_do_data(), with obvious breakage as soon as memory mapping
becomes non-trivial. The fix is obvious.
