Log:
 If the capture is frame sliced at or beyond the TCP 20-byte fixed length portion of the TCP header and tcp_analyze_seq is enabled, TCP analysis is not conducted:  As much of the options field as possible should be dissected and TCP analysis should be performed.
 Patch was tested with snaplens of: 
 49 and 52:  (TCP fixed header incomplete) TCP analysis NOT performed.
 54:  (Fixed header complete but entire options wfield was sliced off) TCP analysis ran and was OK.
 64:  (Fixed header complete but a portion of the options field was missing) Options were dissected to the extent possible.  TCP analysis ran and was OK.
 66:  (Fixed header and options complete) TCP analysis ran and was OK.
 70:  (Fixed header and options complete plus  4 bytes) TCP analysis ran and was OK.
