[ Upstream commit8eaa1d1108] Striding RQ uses MTT page mapping, where each page corresponds to an XSK frame. MTT pages have alignment requirements, and XSK frames don't have any alignment guarantees in the unaligned mode. Frames with improper alignment must be discarded, otherwise the packet data will be written at a wrong address.
