Dear all,

I pushed an enhancement feature to the Gitlab.
https://gitlab.isc.org/isc-projects/dhcp/-/issues/202

This feature is use to resolve:
When DHCP server sends a single instance in Option 17/43/125 from the dhclient-exit-hooks,
dhclient can parse it well.
But if DHCP server sends multiple instances, dhclient only can parse the first one.

The current resolution is simple:
Use a do-while to parse each "struct option_cache-->option" in the oclist.

Is anyone willing to discuss this feature?  Thanks 😊

Best Regards,
Dongyang
