Larysa Zaremba 75d9228982 libeth, idpf: use truesize as XDP RxQ info frag_size ... The only user of frag_size field in XDP RxQ info is bpf_xdp_frags_increase_tail(). It clearly expects whole buffer size instead of DMA write size. Different assumptions in idpf driver configuration lead to negative tailroom. To make it worse, buffer sizes are not actually uniform in idpf when splitq is enabled, as there are several buffer queues, so rxq->rx_buf_size is meaningless in this case. Use truesize of the first bufq in AF_XDP ZC, as there is only one. Disable growing tail for regular splitq.
