[lwip-devel] [patch #10194] Make DHCP module more adjustable

[Simon Goldschmidt]

Follow-up Comment #4, patch #10194 (project lwip):

1) Now I get the purpose of that hook. Instead of making it too generic,
shouldn't we rather make it explicit and let the hook provide what's required
to request the old address? Because the way your example code looks, you're
making the application depend on lwIP internals and there's a very high risk
that your hook won't work with the next version of lwIP when internals have
changed.

You even could add a function 'dhcp_start_from_reboot(netif, old_address)'
that could be called instead of 'dhcp_start(netif)' after boot.
