4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync The default callback function for system generated packet.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync It will free the packet.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Ip4Instance The IP4 child that issued the transmission. It most
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync like is NULL.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Packet The packet that transmitted.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param IoStatus The result of the transmission, succeeded or failed.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param LinkFlag Not used when transmission. check IP4_FRAME_CALLBACK
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync for reference.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Context The context provided by us
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Transmit an IP4 packet. The packet comes either from the IP4
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync child's consumer (IpInstance != NULL) or the IP4 driver itself
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync (IpInstance == NULL). It will route the packet, fragment it,
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync then transmit all the fragments through some interface.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] IpSb The IP4 service instance to transmit the packet
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] IpInstance The IP4 child that issues the transmission. It is
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync NULL if the packet is from the system.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] Packet The user data to send, excluding the IP header.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] Head The caller supplied header. The caller should set
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync the following header fields: Tos, TotalLen, Id, tl,
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Fragment, Protocol, Src and Dst. All the fields are
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync in host byte order. This function will fill in the
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Ver, HeadLen, Fragment, and checksum. The Fragment
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync only need to include the DF flag. Ip4Output will
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync compute the MF and offset for you.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] Option The original option to append to the IP headers
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] OptLen The length of the option
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] GateWay The next hop address to transmit packet to.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync 255.255.255.255 means broadcast.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] Callback The callback function to issue when transmission

4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_SUCCESS The packet is successfully transmitted.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval Others Failed to transmit the packet.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Cancel the Packet and all its fragments.

4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param IoStatus The status returns to the sender.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Prepend an IP4 head to the Packet. It will copy the options and
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync build the IP4 header fields. Used for IP4 fragmentation.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Packet The packet to prepend IP4 header to
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Head The caller supplied header. The caller should set
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync the following header fields: Tos, TotalLen, Id,
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Fragment, Ttl, Protocol, Src and Dst. All the fields
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync are in host byte order. This function will fill in
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync the Ver, HeadLen, and checksum.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Option The orginal IP4 option to copy from
