fxp0 generating lots of interrupts

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello,

I just replaced my old network adaptor with another one and noticed
that vmstat reports lots of interrupts:

vmstat -i | grep fxp
irq11: fxp0                      1532367        394

Is this "normal"?

Relevant parts of dmesg:
 dmesg | grep fxp

I'll update to a more recent current because of security issues, but I
wanted to ask anyway.
