The ID is\nextracted using the helper function cppi5_desc_get_tags_ids() which fills\nin the 16-bit Source Tag into the 'port_id' variable. However, it is only\nthe lower 8-bits of the 16-bit Source Tag that represent the MAC Port ID,\nwhile the upper 8-bits are Hardware-Reserved and carry an arbitrary value.\nWith the existing logic, sporadic kernel crash is observed due to the\nsubsequent driver code accessing out-of-bound memory because of an invalid\nport_id.\n\nHence, fix the port_id extraction logic to use only the lower 8-bits of the\nSource Tag as the MAC Port ID."
