[ Upstream commit b7e5c3e3bfa9dc8af75ff6d8633ad7070e1985e4 ]
incorrectly used ixgbe_lp_map in loops intended to populate the supported and advertised EEE linkmode bitmaps based on ixgbe_ls_map. This results in incorrect bit setting and potential out-of-bounds access, since ixgbe_lp_map and ixgbe_ls_map have different sizes and purposes.
ixgbe_lp_map[i] -> ixgbe_ls_map[i]
Use ixgbe_ls_map for supported and advertised linkmodes, and keep ixgbe_lp_map usage only for link partner (lp_advertised) mapping.
