/**
 * HT IDS: HT Link Port Override params.
 *
 * Provide an absolute override of HT Link Port settings.  No checking is done that
 * the settings obey limits or capabilities, this responsibility rests with the user.
 *
 * Rules for values of structure items:
 * - Socket
 *   - HT_LIST_TERMINAL == end of port override list, rest of item is not accessed
 *   - HT_LIST_MATCH_ANY == Match Any Socket
 *   - 0 .. 7 == The matching socket
 * - Link
 *   - HT_LIST_MATCH_ANY == Match Any package link (that is not the internal links)
 *   - HT_LIST_MATCH_INTERNAL_LINK == Match the internal links
 *   - 0 .. 7 == The matching package link.  0 .. 3 are the ganged links or sublink 0's, 4 .. 7 are the sublink1's.
 * - Frequency
 *   - HT_LIST_TERMINAL == Do not override the frequency, AUTO setting
 *   - HT_FREQUENCY_200M .. HT_FREQUENCY_3600M = The frequency value to use
 * - Widthin
 *   - HT_LIST_TERMINAL == Do not override the width, AUTO setting
 *   - 2, 4, 8, 16, 32 == The width value to use
 * - Widthout
 *   - HT_LIST_TERMINAL == Do not override the width, AUTO setting
 *   - 2, 4, 8, 16, 32 == The width value to use
