Subject: [PATCH net 0/2] iavf: fix double-broken HW hash report
Currently, passing HW hash from descriptors to skb is broken two times.
The first bug effectively disables hash from being filled at all, unless
%NETIF_F_RXHASH is *disabled* via Ethtool. The second incorrectly says
that IPv6 UDP packets are L3, which also triggers CPU hashing when
needed (the networking core treats only L4 HW hash as "true").
The very same problems were fixed in i40e and ice, but not in iavf,
although each of the original commits bugged at least two drivers.
It's never too late (I hope), so fix iavf this time.
Alexander Lobakin (2):
iavf: fix inverted Rx hash condition leading to disabled hash
iavf: fix non-tunneled IPv6 UDP packet type and hashing

To Tony: this is very trivial and tested for a while already, I hope it
could hit one of the first couple RCs :p
