不懂???
This driver is a good example of a driver that exposes a virtual adapter based on a binding to a real physical adapter. It is not a good representative of another class of IM drivers whose underlying physical adapter is not a conventional NIC device, but have to follow IM driver model mainly" because the indications from the driver to the upper layers are not happening in the context of a DPC."
这是ddk中passthru讲的一些passthru 的不足. 我想问的是:前面我懂,但""中的单词意思懂但就是有点不领其意 不知哪位能解释一下. 谁能详细解释一下dpc在写驱动中经常用途? 初学不久忘见谅 |

passthru对于老的网卡,以及老的网卡driver的处理情况
过于简单,但是也不是不能工作,请看ptreceive函数, 搞懂了这个函数,你就明白了这句话的含义。 这个问题在imsample里面不存在。请比较这两个sample 的ptrecevie的区别。 |
