====================
40GbE Intel Wired LAN Driver Updates 2018-03-26

This series contains updates to i40e only.

Jake provides several patches which remove the need for cmpxchg64(),
starting with moving I40E_FLAG_[UDP]_FILTER_SYNC from pf->flags to pf->state
since they are modified during run time possibly when the RTNL lock is not
held so they should be a state bits and not flags.  Moved additional
"flags" which should be state fields, into pf->state.  Ensure we hold
the RTNL lock for the entire sequence of preparing for reset and when
resuming, which will protect the flags related to interrupt scheme under
RTNL lock so that their modification is properly threaded.  Finally,
cleanup the use of cmpxchg64() since it is no longer needed.  Cleaned up
the holes in the feature flags created my moving some flags to the state
field.

Björn Töpel adds XDP_REDIRECT support as well as tweaking the page
counting for XDP_REDIRECT so that it will function properly.
