最後變更 在這個檔案從25276是 23462,由 vboxsync 提交於 15 年 前

NAT: Big changeset:

  1. mbuf_zone has been inroduced.
  2. IPRT timers replaces Slirp's one making poll/WSAWaitForMultipleEvents blocking.
  3. UrgRecv(Thread,Req) introduced for transfering ICMP errors/ARP with highter priority.
  • 屬性 svn:eol-style 設為 native
