Hmm...., It is strange to me that wm(4) use two TX and RX interrupts on
uniprocessor system. The TX and RX interrupt is limited by ncpu.
At my reproduction environment NetBSD/i386(-current updated in today)
on VMware ESXi with e1000e(82574), the wm(4) uses only one TX and RX
interrupt.

Could you show full dmesg?


Thanks,
