Maximum-Receive-Unit (MRU)
从字面意思来看,
Description
This Configuration Option may be sent to inform the peer that the
implementation can receive larger packets, or to request that the
peer send smaller packets.
The default value is 1500 octets. If smaller packets are
requested, an implementation MUST still be able to receive the
full 1500 octet information field in case link synchronization is
lost.
Implementation Note:
This option is used to indicate an implementation capability.
The peer is not required to maximize the use of the capacity.
For example, when a MRU is indicated which is 2048 octets, the
peer is not required to send any packet with 2048 octets. The
peer need not Configure-Nak to indicate that it will only send
smaller packets, since the implementation will always require
support for at least 1500 octets.
A summary of the Maximum-Receive-Unit Configuration Option format is
shown below. The fields are transmitted from left to right.

Maximum-Receive-Unit
The Maximum-Receive-Unit field is two octets, and specifies the
maximum number of octets in the Information and Padding fields.
It does not include the framing, Protocol field, FCS, nor any
transparency bits or bytes.

MRU/MTU:
MTU是以太网数据链路层概念,MRU是PPP链路数据链路层的概念.都是最大传输单元的意思。---tommy zhao

>操作命令

当你在“运行”对话框中成功地运行一个命令,或是在“查找”对话框中成功地查找到一个文件后,你所键入的字符串就会保存在它的下拉列表中。Windows 认为这样可便于你下次再用到它,这些东西就是"MRU" 了!MRU的全称为Most Recently Used,直译理解为最近最多用过的。
但如果下拉列表中的东西太多了,或是你不想别人知道你曾经运行过或查找过什么,怎样才能删掉这些"MRU"清理"MRU"呢?先在“运行”对话框中运行“regedit ”,依次找到HKEY_CURRENT_USER\Softerware\Microsoft\Windows\CurrentVersion\Explorer。在此文件夹下你会发现一个"RunMRU"文件夹,“运行”对话框的"MRU" 即在其中。单击"RunMRU" 文件夹,再在右边的窗口里找到你要删的"MRU" 项,删掉即可。而“查找”对话框中的"MRU" 则在相同路径下的"Doc Find Spec MRU" 文件夹中。
