[lwip-devel] [bug #27352] Change ip_addr from struct to typedef (u32_t)

[Simon Goldschmidt]

Follow-up Comment #51, bug #27352 (project lwip):

As it is now, anyone can have a quick test of not packing ip_addr_t (just
remove the packing directives, there's no need to convert from the struct to a
typedef).

I hope to find the time to review the code in order to copy all addresses to
the stack instead of passing on (unaligned) pointers. However, since that is
quite unsafe (since there is no warning!), I think I'll add an option for that
for now, so that those who want to take the "risk" can try to improve
speed/code size by not packing ip_addr_t.
