both pcnet32 and vmxnet can drive the device.
$ lspci -k ... 02:01.0 Ethernet controller: Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE] (rev 10) Subsystem: Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE] Flags: bus master, medium devsel, latency 64, IRQ 19 I/O ports at 2000 [size=128] [virtual] Expansion ROM at dc400000 [disabled] [size=64K] Kernel driver in use: vmxnet Kernel modules: vmxnet, pcnet32
both kernel modules are loaded,
$ lsmod | grep net pcnet32 32644 0 vmxnet 17696 0 mii 5212 1 pcnet32
as you see, kernel driver in use is vmxnet. is there any policy/algorithm in kernel how to choose from the candidates?
