CVE-2026-98585

eth: fbnic: Avoid rounding zero ring sizes

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

eth: fbnic: Avoid rounding zero ring sizes

roundup_pow_of_two() is undefined for zero. ethtool permits a zero ring
size to reach the driver, where the minimum-size check should reject it.

Leave zero unchanged while rounding nonzero ring sizes. The minimum-size
check then rejects zero deterministically without changing the established
behavior for other values.
