/**
|
|
Transmit an IP4 packet. The packet comes either from the IP4
|
|
child's consumer (IpInstance != NULL) or the IP4 driver itself
|

(IpInstance == NULL). It will route the packet, fragment it,
|
|
then transmit all the fragments through some interface.

|
|
@param IpSb The IP4 service instance to transmit the packet
|
|
@param IpInstance The IP4 child that issues the transmission. It is
|
|
NULL if the packet is from the system.
|
|
@param Packet The user data to send, excluding the IP header.
|
|
@param Head The caller supplied header. The caller should set
|
|
the following header fields: Tos, TotalLen, Id, tl,
|
|
Fragment, Protocol, Src and Dst. All the fields are
|
|
in host byte order. This function will fill in the
|
|
Ver, HeadLen, Fragment, and checksum. The Fragment
|
|
only need to include the DF flag. Ip4Output will
|
|
compute the MF and offset for you.
|
|
@param Option The original option to append to the IP headers
|
|
@param OptLen The length of the option
|
|
@param GateWay The next hop address to transmit packet to.
|
|
255.255.255.255 means broadcast.
|
|
@param Callback The callback function to issue when transmission
|
|
completed.
|
|
@param Context The opaque context for the callback
|
|
|
|
@retval EFI_NO_MAPPING There is no interface to the destination.
|
|
@retval EFI_NOT_FOUND There is no route to the destination
|
|
@retval EFI_SUCCESS The packet is successfully transmitted.

|
@retval Others Failed to transmit the packet.
