Message:

• Renamed hideous get_*_payload_from_ethernet_payload API functions to match the get_payload_from_* naming convention
• trace_get_payload_from_vlan now returns NULL if passed something other than a vlan header or there is no header present after the vlan header, instead of returning the original header that was passed in
• trace_get_payload_from_ip* functions now check if the ip header passed in is NULL and return NULL appropriately

File:

• lib/libtrace.h.in (modified) (3 diffs)
