[edk2] [Patch] MdePkg/UefiDevicePathLib: Fix the wrong MAC address length
Posted by Jiaxin Wu 8 years, 11 months ago 
Network interface type should be checked before the conversion between
text device path node and MAC device path. Otherwise, the MAC text string
can't be converted to the representation of a device node, which leads to
the series failure of network HII configuration(e.g. IP, VLAN, HTTP Boot
configuration in Network Device List).
