Tirthendu Sarkar faa91b839b xsk: move xdp_buff's data length check to xsk_rcv_check ... If the data in xdp_buff exceeds the xsk frame length, the packet needs to be dropped. This check is currently being done in __xsk_rcv(). Move the described logic to xsk_rcv_check() so that such a xdp_buff will only be dropped if the application does not support multi-buffer (absence of XDP_USE_SG bind flag). This is applicable for all cases: copy mode, zero copy mode as well as skb mode.
