Is there a reason why you can't upgrade dhcpcd to something newer?
Anyway, for this specific issue these patches may help:
https://roy.marples.name/git/dhcpcd.git/commit/dhcp.c?h=dhcpcd-6.11.1&id=3ce1402fdc06ba79429831d7ff8c150bec9aee9c
https://roy.marples.name/git/dhcpcd.git/commit/dhcp.c?h=dhcpcd-6.11.1&id=77f0b46ed38e2dca5f663de2e3cb230d33ebaffb

I don't know if they apply cleanly on 6.11.0 or not.
Good luck!

Roy
