I'm teaching myself about ethernet cards, and found a TLDP page. I have CentOS 5.3.
In this section: http://tldp.org/HOWTO/Ethernet-HOWTO-2.html#ss2.4 in the 'Driver as module' subsection, regarding PCI cards, it states that there should be a directory "/lib/modules/`uname -r`/net"
[mykolas@sr1220 ~]$ uname -r 2.6.18-128.1.16.el5 [mykolas@sr1220 2.6.18-128.1.16.el5]$ pwd /lib/modules/2.6.18-128.1.16.el5 [mykolas@sr1220 2.6.18-128.1.16.el5]$ ls build modules.alias modules.ieee1394map modules.ofmap modules.symbols updates extra modules.ccwmap modules.inputmap modules.pcimap modules.usbmap weak-updates kernel modules.dep modules.isapnpmap modules.seriomap source
There's no 'net' directory. I am guessing that the NIC drivers are modules (and not compiled into the kernel) - am I wrong? Or, where are the modules?
