Upcoming firmware introduces command interface revision 3, which
changes the way port capabilities are queried and set. Update the
driver to handle both the new and old command interfaces by adding a
new MLX4_FLAG_OLD_PORT_CMDS that it is set after querying the firmware
interface revision and then using the correct interface based on the
setting of the flag.

New ConnectX firmware introduces FW command interface revision 2,
which requires that for each QP, a chunk of send queue entries (the
"headroom") is kept marked as invalid, so that the HCA doesn't get
confused if it prefetches entries that haven't been posted yet. Add
code to the driver to do this, and also update the user ABI so that
userspace can request that the prefetcher be turned off for userspace
QPs (we just leave the prefetcher on for all kernel QPs).
Unfortunately, marking send queue entries this way is confuses older
firmware, so we change the driver to allow only FW command interface
revisions 2. This means that users will have to update their firmware
to work with the new driver, but the firmware is changing quickly and
the old firmware has lots of other bugs anyway, so this shouldn't be too
big a deal.
Based on a patch from Jack Morgenstein <jackm@dev.mellanox.co.il>.

HCA firmware with incompatible changes to the FW commmand interface is
coming soon. Add a check of the interface revision during
initialization and bail out if the firmware advertises a revision that
the driver doesn't know about. This will avoid strange failures later
if the driver goes on using the wrong interface revision.

The statistics block DMA on 5708 can be messed up occasionally on the
average of about once per hour. If the user is reading the counters
within one second after the corruption, the counters will be all
messed up. One second later, the counters will be ok again until the
next corruption occurs.
The workaround is to disable the periodic statistics DMA. Instead,
we manually trigger the DMA once a second in bnx2_timer(). This
manual trigger of the DMA avoids the problem.
As a consequence, we can only allow 0 or 1 second settings for
ethtool -C statistics block.

There's a bug in the driver that only initializes half of the context
memory on the 5708. Surprisingly, this works most of the time except
for some occasional netdev watchdogs when sending a lot of 64-byte
packets. The fix is to add the missing code to initialize the 2nd
halves of all context memory.

We need to pass the same dev_id to free_irq() and request_irq(). When

We may call mlx4_dispatch_event() before mlx4_register_device() is
called for a device, because for example a catastrophic error happens
immediately after we enable interrupts. Therefore priv->ctx_list and
priv->ctx_lock need to be initialized earlier.
This bug was actually exposed by the MSI-X bug that returned IRQ numbers
to drivers in reverse order, so that the first FW command
interrupt looked to mlx4 like a catastrophic error.

The reserved6 field should be 64 bits, not just 16 bits. Without
this, the structure does not match the hardware layout on 32-bit
architectures: the db_rec_addr field ends up at offset 52 instead of
offset 56. The bug slipped by because the alignment of __be64 members
ends up putting it in the right place on x86-64.

The bug is caused by code that always set
(TG3_FLAG_USE_MI_INTERRUPT | TG3_FLAG_USE_LINKCHG_REG) on all Dell's
onboard devices. With these 2 flags set, the link status is polled
by tg3_timer() and will only work when the PHY is set up to interrupt
the MAC on link changes. This breaks 5906 because the 5906 PHY does
not support TG3_FLAG_USE_MI_INTERRUPT the same as other PHYs.
For correctness, only Dell's onboard 5701 needs these 2 flags to be
set. This change will fix the 5906 problem and will change other
Dell devices except 5700 and 5701 to use the more efficient
interrupt-driven link changes.
Update version to 3.77.

The current smc91x I/O routines ifdef the solution engine subtypes
individually, which is rather bogus, as they can simply use
CONFIG_SOLUTION_ENGINE instead. This fixes it for some of the other
solution engines that weren't included in the ifdef list (SH7206
specifically).
There are also inb/outb definitions which are totally bogus (missing

try to use a 16-bit access to fake 8-bit access). Kill that nonsense off

This restores the previously removed netif_poll_enable call in e1000_open.
It's needed on all but the first call to e1000_open for a NIC as
e1000_close always calls netif_poll_disable.
netif_poll_enable can only be called safely if no polls have been
scheduled. This should be the case as long as we don't enter our IRQ
handler.
In order to guarantee this we explicitly disable IRQs as early as possible
when we're probing the NIC.
