This series contains fixes to ixgbe.

Alex fixes up the adaptive ITR scheme for ixgbe which could result in a
value that was either 0 or something less than 10 which was causing
issues with hardware features, like RSC, that do not function well with
ITR values that low.

Ilya Maximets fixes the ixgbe driver to limit the number of transmit
descriptors to clean by the number of transmit descriptors used in the
transmit ring, so that the driver does not try to "double" clean the
same descriptors. 

The following are changes since commit f4b752a6b2708bfdf7fbe8a241082c8104f4ce05:
  mlx4: fix spelling mistake "veify" -> "verify"
and are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-queue 10GbE

Alexander Duyck (1):
  ixgbe: Prevent u8 wrapping of ITR value to something less than 10us

Ilya Maximets (1):
  ixgbe: fix double clean of Tx descriptors with xdp

Pulled, thanks Jeff.
