[ Upstream commit 2a83891130512dafb321418a8e7c9c09268d8c59 ]
IPV6 addresses are purged when setting the number of rx/tx
rings using ethtool -G. The function aq_set_ringparam
calls dev_close, which removes the addresses. As a solution,
call an internal function (aq_ndev_close).
Fixes: c1af5427954b ("net: aquantia: Ethtool based ring size configuration")
