-The following issues exist with the EFI Socket Library:\r
-\r
-* Don't run socket applications or the socket driver for a long time - The IPv4Config\r
- and DHCP protocols are not properly running the renew and lease expiration timers.\r
- When the DHCP lease expires it is possible for a duplicate IP address to exist on\r
- the network. HSD 206136\r
-\r
-* Network adapters must be initialized prior to running the socket application - Static\r
- and dynamic IP address need to be properly assigned to the network adapters on the\r
- system. Note that sockets does not assign the IP addresses since it does not\r
- understand how the system is connected to the network!\r
-\r
-* The default device must contain the Efi\etc directory populated with files containing\r
- the proper network configuration - A template set of files is in StdLib\Efi\etc. Note\r
- that the resolv.conf file contains the set of DNS servers.\r
-\r
-* Since DHCP is not running when the sockets application is running, the last negotiated\r
- packet is no longer available. As a result, any of the options that DHCP did negotiate\r
- are no longer available for sockets such as the list of DNS servers.\r
-\r
-* DHCP does not request the domain name and domain name server (DNS) addresses. This\r
- requires that sockets use configuration files in Efi\etc!\r
-\r
-* TCPv4 transfer rate is slow (< 10 Mbits/sec) - This is an unidentified issue.\r
-\r
-* Tcp4Dxe transmits more urgent data than is sent through sockets when normal data is\r
- queued for transmission before the urgent data. HSD 206365\r
-\r
-* Raw socket applications are not able to pass the IP header as part of their\r
- payload by using the IP option IP_HDRINCL. This is because the UEFI IPv4 driver\r
- (Ip4Dxe) does not support RawData. HSD 206136\r
-\r
-* Only version 4 of the UEFI network stack is supported\r
