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

[Bill Auerbach]

Follow-up Comment #18, bug #27352 (project lwip):

Yeah, sorry - it's Monday.  It's done not only in the callbacks though.  As
often as it's used and seeing that a 4-byte memcpy has huge overhead I would
benchmark this change before deciding on that choice.  I hope it's not being
chosen because of IPv6.  IPv6 is far from complete and not widely used or
required in small embedded devices.
