net: add ETH_P_802_3_MIN
Add a new constant ETH_P_802_3_MIN, the minimum ethernet type for
an 802.3 frame. Frames with a lower value in the ethernet type field
are Ethernet II.
Also update all the users of this value that David Miller and
I could find to use the new constant.
Also correct a bug in util.c. The comparison with ETH_P_802_3_MIN
should be >= not >.
As suggested by Jesse Gross.
Compile tested only.
