From: Louis Peens <louis.pe...@netronome.com>
[ Upstream commit f614e536704d37326b0975da9cc33dd61d28c378 ]
Fix an issue where the driver wrongly detected ipv6 neighbour updates
from the NFP as corrupt. Add a reserved field on the kernel side so
it is similar to the ipv4 version of the struct and has space for the
extra bytes from the card.
Fixes: 9ea9bfa12240 ("nfp: flower: support ipv6 tunnel keep-alive messages from
fw")
