Modified Files:
        src/sys/dev/pci: if_wm.c

Log Message:
actually writing always the checksum offload context descriptor
makes the hw do extra processing, avoid doing that if possible -
on my computer with I219 this results in about 2% speedup in Tx performance

change adoped from FreeBSD

XXX should be also done for multiqueue case, but I don't have hw to test it
