Is there an easy way to identify which wm I have?  Does the following 
device need this commit in order to use offload?  Or will this one work 
with an earlier rev of the driver?

# dmesg | grep wm
wm0 at pci2 dev 0 function 0: Intel i82574L (rev. 0x00)
wm0: interrupting at ioapic1 pin 24
wm0: PCI-Express bus
wm0: 256 word (8 address bits) SPI EEPROM
wm0: Ethernet address bc:ae:c5:30:d9:8a
ukphy0 at wm0 phy 1: OUI 0x000ac2, model 0x000b, rev. 1
