Xin Long df2729c323 sctp: check for dst and pathmtu update in sctp_packet_config ... This patch is to move sctp_transport_dst_check into sctp_packet_config from sctp_packet_transmit and add pathmtu check in sctp_packet_config. With this fix, sctp can update dst or pathmtu before appending chunks, which can void dropping packets in sctp_packet_transmit when dst is obsolete or dst's mtu is changed. This patch is also to improve some other codes in sctp_packet_config. It updates packet max_size with gso_max_size, checks for dst and pathmtu, and appends ecne chunk only when packet is empty and asoc is not NULL. It makes sctp flush work better, as we only need to set up them once for one flush schedule. It's also safe, since asoc is NULL only when the packet is created by sctp_ootb_pkt_new in which it just gets the new dst, no need to do more things for it other than set packet with transport's pathmtu.
