kernel: i40e: add validation for ring_len param

A flaw was identified in the Intel “i40e” Ethernet driver in the Linux Kernel where the ringlen parameter supplied by a VF virtual function is passed unchecked to the hardware memory context. If a malicious Virtual function provides a too-large or misaligned ringlen, it may allow the device to...
