55dffe79b3 tg3: Disable 5717 serdes and B0 support
The B0 revision of the 5717 will not get enough testing by the time
2.6.33 ships.  Since the kernel is already at RC3, serdes support
will require too many patches to fix.  For these reasons, this patch
disables 5717 serdes support and will refuse to attach to all 5717
devices that are later than an A0 revision.

d1ec96af77 tg3: Add reliable serdes detection for 5717 A0
The serdes status bit does not work as intended for the 5717 A0.
This patch implements an alternative detection scheme that will only be
valid for A0 revisions.

86cfe4ff02 tg3: Fix std rx prod ring handling
There are some tg3 devices that require the driver to post new rx
buffers in smaller increments.  Commit
4361935afe, "tg3: Consider
rx_std_prod_idx a hw mailbox" changed how the driver tracks the rx
producer ring updates, but it does not make any special considerations
for the above-mentioned devices.  For those devices, it is possible for
the driver to hit the special case path, which updates the hardware
mailbox register but skips updating the shadow software mailbox member.
If the special case path represents the final mailbox update for this
ISR iteration, the hardware and software mailbox values will be out of
sync.  Ultimately, this will cause the driver to use a stale mailbox
value on the next iteration, which will appear to the hardware as a
large rx buffer update.  Bad things ensue.

The fix is to update the software shadow mailbox member when the special
case path is taken.

13fa95b039 tg3: Fix std prod ring nicaddr for 5787 and 57765
Commit 87668d352a, titled "tg3: Don't
touch RCB nic addresses", tried to avoid assigning the nic address of
the standard producer ring.  Unfortunately, the default nic address is
not correct for the 5787, the 5755M, or the 57765.  This patch
reenables the old behavior and opts out of the assignment only
for the 5717.

f3766c26a5 sfc: Fix conditions for MDIO self-test
The MDIO self-test should not be run on boards without an MDIO PHY,
such as SFN5122F-R3 and later revisions.  It should also not try to
address a specific MMD in an MDIO clause 22 PHY.  Check the
mode_support field to decide which mode to use, if any.

55029c1d65 sfc: Fix polling for slow MCDI operations
When the interface is down and we are using polled mode for MCDI
operations, we busy-wait for completion for approximately 1 jiffy
using udelay() and then back off to schedule().  But the completion
will not wake the task, since we are using polled mode!  We must use
schedule_timeout_uninterruptible() instead.

fddaa1aff8 e1000e: MDIO slow mode should always be done for 82577
A previous 82577 workaround that set the MDIO access speed to slow mode for
every PHY register read/write when the cable is unplugged should instead
set the access mode to always be slow before any PHY register access.
Since the mode bit gets cleared when the PHY is reset, set the mode after
every PHY reset.

9db2f1bec3 sky2: Fix oops in sky2_xmit_frame() after TX timeout
During TX timeout procedure dev could be awoken too early, e.g. by
sky2_complete_tx() called from sky2_down(). Then sky2_xmit_frame()
can run while buffers are freed causing an oops. This patch fixes it
by adding netif_device_present() test in sky2_tx_complete().

39825f4dc9 iwlwifi: silence buffer overflow warning
Smatch (and presumably other static checkers) complain that MAX_TID_COUNT is
past the end of the array.  In the resulting discussion, Zhu Yi pointed out
that this value is not used in real life and the assignment was only there to
silence a gcc warning.

If there were a bug in the surrounding code and the value were used, the
WARN_ON(!qc) would print a warning before the crash.

c91c3efca5 iwlwifi: disable tx on beacon update notification
On beacon change update notification from mac we are not disabling
the tx in adhoc mode. Mac sends BSS_CHANGED_BEACON_ENABLED when
station leaves IBSS. Driver should indicate uCode to not to send
anything on receiving this notification.

Functionality to indicate uCode is duplicated across
two notifications so created a common function called iwl_set_no_assoc.

b7a9216c5a e1000e: fix and commonize code for setting the receive address registers
Fix e1000e_rar_set() to flush consecutive register writes to avoid write
combining which some parts cannot handle.  Update e1000e_init_rx_addrs()
to call the fixed e1000e_rar_set() instead of duplicating code.

Also change e1000e_rar_set() to _not_ set the Address Valid bit if the MAC
address is all zeros.

ca777f9c09 e1000e: e1000e_enable_tx_pkt_filtering() returns wrong value
e1000e_enable_tx_pkt_filtering() will return a non-zero value if the
driver fails to enable the manageability interface on the host for
any reason; instead it should retun zero to indicate filtering has been
disabled.  Also provide a single exit point for the function.

Adaptive IFS which involves writing to the Adaptive IFS Throttle register
was being done for all devices supported by the driver even though it is
not supported (i.e. the register doesn't even exist) on some devices.  The
feature is supported on 8257x/82583 and ICH/PCH based devices, but not
on ESB2.

to avoid issues with EEH (same fix that recently was submitted for ixgbe).

The Davicom DM9100 and DM9102 chips are used on the motherboards of
some SPARC systems (supported by the tulip driver) and also in PCI
expansion cards (supported by the dmfe driver).  There is no
difference in the PCI device ids for the two different configurations,
so these drivers both claim the device ids.  However, it is possible
to distinguish the two configurations by the presence of Open Firmware
properties for them, so we do that.

530e557ab2 mv643xx_eth: don't include cache padding in rx desc buffer size
If NET_SKB_PAD is not a multiple of the cache line size, mv643xx_eth
allocates a couple of extra bytes at the start of each receive buffer
to make the data payload end up on a cache line boundary.

These extra bytes are skb_reserve()'d before DMA mapping, so they
should not be included in the DMA map byte count (as the mapping is
done starting at skb->data), nor should they be included in the
receive descriptor buffer size field, or the hardware can end up
DMAing beyond the end of the buffer, which can happen if someone
sends us a larger-than-MTU sized packet.

This problem was introduced in commit 7fd96ce47f ("mv643xx_eth:
rework receive skb cache alignment", May 6 2009), but hasn't appeared
to be problematic so far, probably as the main users of mv643xx_eth
all have NET_SKB_PAD == L1_CACHE_BYTES.

Commit 8bf3d79bc401ca417ccf9fc076d3295d1a71dbf5 enabled EEPROM
checksum checks to avoid bogus bug reports but failed to address
updating the code to consider devices with custom EEPROM sizes.
Devices with custom sized EEPROMs have the upper limit size stuffed
in the EEPROM. Use this as the upper limit instead of the static
default size. In case of a checksum error also provide back the
max size and whether or not this was the default size or a custom
one. If the EEPROM is busted we add a failsafe check to ensure
we don't loop forever or try to read bogus areas of hardware.
