panic: tcp_addoptions: TCP options too long w/ with TCP_SIGNATURE support

[Mark Atkinson]

I have a 8-CURRENT kernel compiled with the following options, from about
march 5th. 

options        IPSEC
options        TCP_SIGNATURE           #include support for RFC 2385
device         crypto
device         cryptodev

device          pf
device          pflog

device         vlan

I also have a external server supporting MD5 tcp signatures.  If I give the
following command:

/usr/src/tools/regression/netinet/tcpconnect/tcpconnect client 172.16.1.145
7 1 tcpmd5
