* HPNS:
*
- * Our current MQ 5.3 EGD requires compatability-mode sockets
- * This code forces the mode to compatibility if required
- * and then restores the mode.
+ * This code forces the use of compatibility mode if required on HPE NonStop
+ * when coreutils PRNGD is used and then restores the previous mode
+ * after establishing the socket. This is not required on x86 where hardware
+ * randomization should be used instead of EGD available as of OpenSSL 3.0.
+ * Use --with-rand-seed=rdcpu when configuring x86 with 3.0 and above.
*
* Needs review:
*
* The better long-term solution is to either run two EGD's each in one of
* the two modes or revise the EGD code to listen on two different sockets
- * (each in one of the two modes).
+ * (each in one of the two modes) or use the hardware randomizer.
