Solve Linux compile kernel nic driver problem

As a result of the project, the need to compile the kernel, modify the TUN source support sharing mode, compile the kernel encountered the network card driver lost problem, nonsense, said directly to solve the problem, I understand the bottom of the things very shallow, so the way to solve the problem is very clumsy.

OS version:centos 5.9 kernel:2.6.18-402 Update kernel version: 2.6.20

Because yum inside the kernel header file and card package does not have too much source code. C files. So can only download similar version from www.kernel.org, some people must say that you are not next to the latest kernel version, a: such as the kernel version span is relatively large, I worry that there will be a variety of problems, a lot of old compiler options new version of the kernel does not support.

First download the original system development package and header file:

Shell $> Yum Install kernel-devel kernel-headers
Unzip the 2.6.20 Kernel compression Pack and start compiling the kernel
Shell $> MV linux-2.6.20.tar.bz2/usr/src/
Shell $> cd/usr/src/
Shell $> Tar jxvf linux-2.6.20.tar.bz2
Shell $> CD linux-2.6.20

# Modify the source code to change their needs, I modified the Tun related source files.

Shell $> make Mrproper

# still an error, look at the log or Unknown symbol Pci_channel_offline
# and then I thought, did I compile in the old kernel and see if it went wrong? Results in the old kernel there is no error, I was looking at the old kernel of the pci.h file, found the Pci_channel_offline method:

static inline int pci_channel_offline (struct Pci_dev *pdev)

Return (pdev->error_state!= pci_channel_io_normal);
}
