[lwip-devel] [bug #54574] Comment to LWIP_DHCP_CHECK_LINK_UP might need improvement

[Simon Goldschmidt]

Follow-up Comment #1, bug #54574 (project lwip):

Hmm, I don't think this option is needed at all: while dhcp works without the
NETIF_FLAG_LINK_UP flag (because udp_sendto_if() is used), ip_route() requires
netifs to have a link.

So this seems like an old outdated config option: netifs not supporting link
state change must set the link as up in their init function.
