Misuse of retransmisson of DHCPDISCOVER in Dhcp4 drive, the root cause is that DHCP doesn't retransmit discover message when timeout.
[Solution]:
Correct the mechanism for discover message.
[Impaction]:
Dhcp4Dxe.

Problem with PXE boot to Windows Server 2008 install. The reason is that UdpRead and UdpWrite interfaces cannot work well with the same UDP instance.
[Solution]
Use separate instances for UDP Read and UDP write in UefiPxeBC module.
[Impaction]:
UefiPxeBcDxe and Udp4Dxe module.

Fixed one bug in PciBus. PciBus doesn't clear the bridges bus number for all the root bridges before scanning any of them.
[Description]:
The static IP configuration no long works in the EDK 1.04 network package. The cause is that changing the type of EFI_IP4_IPCONFIG_DATA.RouteTable from a variable length array to a pointer is not clean. If the whole structure is read from variable, the pointer is invalid.
[Solution]
Fix the pointer before using it
[Impaction]:
Ip4ConfigDxe module.

Memory may leak because the handles in IScsiUpdateDeviceList is not freed if the "iSCSIDeviceList" already exists
[Impaction]
add Free() func to free memory properly.

solve the big file transfer issue using ISCSI
[Impaction]
change the control flow on IScsiExecuteScsiCommand function
[Reference Info]
The original design incorrectly uses a timer (its span is usually 2 seconds) to ensure the timely execution of CMD PDU send by initiator. For example: When initiator delivers a CMD PDU(WRITE command) in which the ExpDataXferLength filed is larger than DataSegmentLength field, according to ISCSI protocol spec, the target will respond it with a R2T PDU which is followed by a sequential DATA-OUT PDUs. In this situation, the original code may loop to deal with the arrival packet until initiator receives a RESPONSE PDU or the timer is expired. This way may cause the bigger file is more likely to fail.

solve the x64 exception issue when unloading iSCSI driver
[Impaction]
add some handler for failure branch and prohibit the additional ISCSI INITIATOR NAME PROTOCOL from being installed.
[Reference Info]
this bug is reported by DELL. it causes an exception in x64 on unloading iscsi driver.

fix the wrote data corrupt bug about iscsi
[Impaction]
modify the IScsiGenerateDataOutPduSequence() function in MdeModulePkg.
[Reference Info]
when writing some data from local disk into remote iscsi disk, the data may be corrupt.The root cause is caused by the data out PDU's offset is not created correctly.
