[lwip-devel] [bug #49139] IGMP "All Systems" vs MLD "All Nodes" inconsistency

[Dirk Ziegelmeier]

Follow-up Comment #2, bug #49139 (project lwip):

Regarding the second part (merging the callbacks):

Problem is IGMP code only uses ip4_addr_t internally and MLD6 code uses
ip6_addr_t. But a common callback needs ip_addr_t. Consequence: Creation of
ip_addr_t on stack just for the callback, and the first thing the called
function does is "if IP_IS_V6(ip)" checking. So this change does not implement
an improvement.
