[dpdk-dev] [PATCH 25/39] net/ixgbe/base: set default autoneg speed at reset

[Xiao Wang]

This patch avoids the situation where we initialize adapter and not
yet set up phy.autoneg_advertised speeds. In that case we could end
up in having no autoneg speeds enabled and get no link until we
reset link and set autoneg speeds correctly.
