After discussing it internally, we found a way to support unaligned XSK with Striding RQ, and the hardware is compatible with this way. I have performed some testing, and it looks working. Your patch only adds support for the new handle format to our driver, and I've made another patch that actually enables the new feature (makes mlx5e accept frame sizes different from PAGE_SIZE).
