96 | * NAME: tp_consistency() | |
97 | * | |
98 | * CALLED FROM: | |
99 | * tp_ctloutput(), tp_input() | |
100 | * | |
101 | * FUNCTION and ARGUMENTS: | |
102 | * Checks the consistency of options and tpdusize with class, | |
103 | * using the parameters passed in via (param). | |
104 | * (cmd) may be TP_STRICT or TP_FORCE or both. | |
105 | * Force means it will set all the values in (tpcb) to those in | |
106 | * the input arguements iff no errors were encountered. | |
107 | * Strict means that no inconsistency will be tolerated. If it's | |
108 | * not used, checksum and tpdusize inconsistencies will be tolerated. | |
109 | * The reason for this is that in some cases, when we're negotiating down | |
110 | * from class 4, these options should be changed but should not | |
111 | * cause negotiation to fail. | |
112 | * | |
