Installing VM NIC with Intel diver e1000

I have installed Ubuntu Linux image in a VMware virtual box. Then I added three NIC interfaces. They all have Intel e1000 as the driver when I validated with ethtool command.

Then I installed another Custom Linux image in a VMware virtual box. Then I added three NIC interfaces as earlier. They all have pcnet from AMD as the driver when I validated with ethtool command.

lspci | grep -i net

/etc/udev/rules file

/sbin/modprobe -c | grep pcnet32
alias pci:v00001022d00002000sv*sd*bc*sc*i* pcnet32
alias pci:v00001022d00002001sv*sd*bc*sc*i* pcnet32
alias pci:v00001023d00002000sv*sd*bc02sc00i* pcnet32

When I see modprobe entries in Custom Linux I also see e1000 entries.

It would be great to know if there is a way to configure NIC using e1000 in custom Linux. I see some reference on “compatible” entries and mod alias entries. As I am coming from web application development, I am not sure how to make use of these references and steps so that I get NIC that supports DPDK Intel(e1000) in custom Linux.

As per my understanding, once the device added in the system, OS will check in mod alias based on compatible entry and load right driver. I am not sure whether I need to check some settings in Custom linux compilation

Would appreciate your help with this.
