Description

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.
