What it is

In the Linux kernel, the following vulnerability has been resolved:

ixgbe: fix incorrect map used in eee linkmode

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.
