====================
40GbE Intel Wired LAN Driver Updates 2017-10-09

This series contains updates to i40e and i40evf only.

Jake fixes missed flag conversion from u64 to u32.  Fixes a deafult ITR
value issue where the driver defaults to an ITR value of half the
expected value (in terms of minimum microseconds between interrupts).  So
fix this by changing the default values to be calculated using the
ITR_REG_TO_USEC() macro which indicates that we are converting from the
register units into microseconds. Updates the drivers to bump the tail in
increments of 8 and double the number of descriptors we will bundle into
one tail bump when receiving.  With the recent kernel support for
enabling XPS and QoS at the same time, we no longer need to worry about
the number of traffic classes when enabling XPS.

Lihong converts the use of hash_for_each() to hash_for_each_safe() to
safely remove a hash entry.  Adds a check for the return value for
find_first_bit() in the case that it returns the size passed to search.

Alan fixes a bug in which filters are erroneously removed if they are
removed and then added again.  So make sure that when adding a filter, if
we find it already existed in our list, make sure it is not marked to be
removed.

Jayaprakash adds the retrying of PHY reads when the I2C is busy for a
maximum period of 500ms.

Rami fixes code comment typo.

Stefano Brivio simplifies the code by removing the use of a local
return code variable and simply return the results of the read function.
