This looks good -- but I'm a bit confused by this segment of code:
+ #if NVLAN > 0
+ ifp->if_data.ifi_hdrlen = sizeof(struct ether_vlan_header);
+ #else
+ if (sc->not_82557) {
+ ifp->if_data.ifi_hdrlen = sizeof(struct ether_vlan_header);
+ }
+ #endif
Can you explain the logic here? (This seems to interfere with the
loadability of this module.)
