From: Jacob Keller <jacob.e.keller@intel.com>
This patch removes the use of hw_dbg in ixgbevf when the ixgbe_get_regs function
is called from ethtool. This goes along side a patch to ethtool which enables
proper support for ixgbevf pretty-printing of registers.

Since we are already checking for read failure in check_link we don't need
to do it here. Instead just make sure the watchdog task gets scheduled, if
we are up, and it can be done there. This will better follow igbvf method
of handling a mailbox event and message timeout.

New function was added to wait for Rx queues to be disabled before
disabling NAPI. This function also allows us to modify
ixgbevf_rx_desc_queue_enable() to better match ixgbe. I also cleaned up
some msleep calls to usleep_range while I was in this code anyway.

After this patch the API negotiation will occur in the reset path. So now
the PF will be informed of the API version earlier. This will also require
the mailbox lock to be initialize sooner as well.

To: davem; +Cc: Jacob Keller, netdev, gospo, sassmann, Jeff Kirsher
From: Jacob Keller <jacob.e.keller@intel.com>
This patch renames the LL_EXTENDED_STATS and some of the functions required to
implement busy polling in the ixgbe driver, in order to remove the marketing
"low latency" blurb which hides what the code actually does.
This furthers work which was requested by Linus Torvalds when the initial busy
poll code was included in the kernel. The code in the ixgbe driver itself was
never properly renamed to reflect the change to busy polling as the title.

These functions look fine to me.

In case this fails, is the interface in a consistent state where is it
safe to reconfigure the interface again or to unbind the driver?
If it fails, and the interface was up, shouldn't it call dev_close() so
that it's obviously down and the user can then try to bring it up again?
Ben.

Good question. I was delayed in replying as I was giving Laura a chance to reply to this thread.
We call our close routine igb_close(), if the device is up. This does not call dev_close() specifically, however it’s a good suggestion for the error case. I'll update the patch.
Thanks,

Pulled, thanks Jeff.
Please address Ben Hutching's concerns about the state of the device
after a number of channels configuration failure with follow-on
changes, if necessary.
Thanks.
