Björn Töpel 8ce29c679a i40e: tweak page counting for XDP_REDIRECT ... This commit tweaks the page counting for XDP_REDIRECT to function properly. XDP_REDIRECT support will be added in a future commit. The current page counting scheme assumes that the reference count cannot decrease until the received frame is sent to the upper layers of the networking stack. This assumption does not hold for the XDP_REDIRECT action, since a page (pointed out by xdp_buff) can have its reference count decreased via the xdp_do_redirect call. To work around that, we now start off by a large page count and then don't allow a refcount less than two.
